Abstract: Two field experiments, several greenhouse and laboratory experiments were conducted during the course of study to evaluate the allelopathic potential of two sunflower (Helianthus annuus L.) cultivars on companion weeds and weeds grown in mungbean (Vigna radiata L. R. Wilczek) field alone and in combination with reduced rate herbicide, and to determine the chemical and genetical bases of allelopathic traits in the test cultivars. The aim of the first experiment was to test whether the variation in weed growth between the sunflower cultivars (Shumoose and Sin Altheeb), which was observed in the field, was due to differences in their allelopathic potential. Results showed the ability of both cultivars to reduce weed population and biomass with the superiority of Shumoose cultivar in suppression of weed density at 60 and 120 days after sowing compared to Sin Altheeb. Weed biomass was significantly reduced up to 90 and 71% by Shumoose and Sin Altheeb cultivars, respectively. Stair case experiment indicated that root exudates of Shumoose cultivar showed more suppression to weeds than Sin Altheeb giving additional evidence for the superiority of Shumoose cultivar in its allelopathic weed suppression. Chemical analysis by High performance liquid chromatography indicated the presence of 9 compounds in root exudates of Sin Altheeb and 8 compounds in Shumoose, and all are Phenolic in nature. However, total of the isolated phenolics was doubled in Shumoose than in Sin Altheeb. Most of the isolated chemicals are reported to have inhibiting ability for germination and growth of plants, including weeds. Second field experiment was undertaken to explore the response of weeds and mungbean crop to soil incorporated with sunflower residues in combination with lower rate of a pre - plant herbicide (trifluralin). Sunflower residues of the two cultivars Shumoose and Sin Altheeb at 3.2 and 6.4 t ha - 1 were used either alone or in combination with trifluralin at 1.2 L ha - 1 (50% of label rate). Weedy check (control), trifluralin at full label rate (2.4 L ha - 1), and weed free treatments were also included for comparison. Plots treated with 50% of label rate of herbicide and amended with sunflower residues of cultivar Sin Altheeb recorded least weed density and dry biomass and this suppression was much greater than the residue treatments alone and more than cultivar Shumoose. Application of herbicide at 50% rate in plots amended with Sin Altheeb residue resulted yield 64 % more than with the label rate of herbicide treatment. Chromatographic analysis of sunflower amended field soil revealed the presence of several potent allelopathic compounds in the residues of both cultivars with greater quantity (355.5 µg/ml) in Sin Altheeb than in Shumoose (250.9 µg/ml). Dynamics of release, decomposition and degradation of allelochemicals into the soil showed that different compounds exhibited differential behavior for these processes. Overall quantity of allelochemicals started to increase after 2 weeks of decomposition and peaked at 4 week of decomposition (180.1 ppm) then declined sharply in their quantities thereafter. Periods indicating higher quantities of total phenolics as shown by chromatographic analysis was coincided with the periods in which higher suppressive activity against weeds grown under field conditions. Bioassay of sunflower residues decomposed in soil at different times on Echinochloa colonum L, one of the weeds dominated the mungbean field, revealed that residues of both cultivars suppressed growth of E. colonum weed. The phytotoxicity started after 2 weeks and persisted for 8 weeks. However, Sin Altheeb residues showed greater inhibition than Shumoose cultivar at the last three decomposition periods. Shumoose residues recorded appreciable reduction to the growth of test weed compared to Sin Altheeb. The effect of residues of both cultivars on chlorophyll content and ions uptake in Amaranthus retroflexus L. weed revealed that residues of both species reduced chlorophyll content of leaves and the reduction increased with the increased residue rate. Sin Altheeb cultivar residues were more inhibitory than Shumoose at the lower residue rate. In the same weed, ions uptake was significantly averted by the residues of both cultivars. P and K was significantly increased over control, while Ca, Mg an Fe were found to be decreased over control due to application of sunflower residues in soil at 8 g per kg soil. N was the only test element that did not significantly influence by the residue treatments. No significant differences were found in the test ion uptake between the test sunflower cultivars. Results of using RAPD technique on the sunflower genomic DNA revealed that all the 19 primers used in this study scored different amplification monomorphic and polymorphic bands in the tested genotypes with 12 primers generated polymorphic bands. These bands present in one cultivar and absent in another. They could be responsible for allelopathic trait or secondary compounds associated with this phenomenon. Further work is recommended to analyze the sequence of this band to find out whether it is related to allelopathic trait or not.

The aim of the study was studying response of two okra varieties (Al - Husenawyia and Al - Pteira) humic acid and zolfast application methods (foliar and addition to irrigation water) and this concentration (recommended and doubled) on growth and productivity as well as leaf mineral and fruit medicinal active constituents.The humic acid and zolfast formulas were added by the use of hand sprayer or with irrigation water with the recommended and doubled concentrations for humic acid and zolfast as foliar spraying were 1 ml.L - 1 and 2 ml.L - 1 if doubled respectively while when used with irrigation water 4.8 ml.L - 1 and 9.6 ml.L - 1 if double for humic acid 7.2 and 14.4 ml.L - 1 for zolfast if doubled.The design of the experiment was Randomized complete blocks in a factorial arrangement (2×2×5) in three replications. The RLSD at 0.05 was used as a method to compare means separation treatment effect was evident. The results showed : 1 - Al - Husenawyia variety was superior in total leaf area, vegetative fresh and dry weights, root fresh and dry weights, P% and content addition to specific leaf weight, relative growth rate, fruit length, number of fruit/plant, fruits yield compared to Al - Pteira. Percentage of protein, carbohydrates, total soluble solids, caprylic, lauric saturated fatty acids and all the unsaturated fatty acids. Mucilage, folic acid and oil refractive index were also higher with Al - Husenawyia compared to Al - Pteira had higher stem diameter, fruit fresh and dry weight, K%, boron content and percentage of saturated fatty acids (Myristic, Palmatic, Stearic, Arachidic and Behinic). Ca% was the same for both cultivars.2 - Foliar application method of humic acid and zolfast showed beneficial effect on and all parameters studies except root fresh and dry weight and percentage of saturated fatty acids increased with irrigation water (except Lauric acid which was increased with foliar application). Methods of application did not affect stem diameter, Ca% in leaves and fruit total soluble solids.3 - Although the double recommended concentrations of humic acid and Zolfast reduced saturated fatty acids significantly their recommended concentration lowered saturated fatty acids (Caprylic, Myristic, Palmatic, Stearic, Arachidic and Behinic) compared to control treatment. Percentage of fiber was lower with the use of zolfast compared to humic acid and control. While K% was lowered when zolfast used in the double recommended concentration. No significant difference were found between the recommended concentrations of humic acid or zolfast in stem diameter, total leaf area, relative growth rate, vegetative dry weight, root dry weight, P%, Ca%, boron content, fruit length, number of fruit/ plant, fruit dry weight, mucilage, carbohydrates%, folic acid, oil%, percentage of saturated fatty acids (Caprylic, Myristic, Palmatic and Arachidic) and unsaturated fatty acids (Oleic and Linoleic) and the percentage of unsaturated fatty acids/saturated.4 - The interaction between cultivars and methods of application revealed that foliar application of both humic acid and zolfast reduced saturated fatty acid (Caprylic, Myristic, Palmatic, Stearic and Arachidic) significantly of both cultivars, compared to their addition to irrigation.5 - The interaction between cultivars and substances of application (humic acid and zolfast concentrations revealed that both cultivars had different response in some traits of studied to applied concentrations of humic and zolfast. Al - Husenawyia variety had higher vegetative fresh weight, root dry weight and fruit of mucilage content with the double recommended humic acid. While Al - Pteira variety had higher TSS% and Lauric acid% when used the double recommended concentration of zolfast.6 - The interaction between methods of application and concentrations of application substances showed superior effect on some studied parameters. Foliar application method was superior on addition to irrigation application with all concentrations except root fresh and dry weight and saturated fatty acids% (except Lauric acid) which were increased when added to the irrigation water to all concentrations of application substances. The same interaction did not revealed significant difference in stem diameter, Ca% and fruit fresh and dry weight.7 - The three way interaction factors studied in the experiment revealed an increase in growth parameter of both cultivars when humic acid and zolfast were added in their higher concentration (double recommended) by foliar application expect root fresh and dry weight and saturated fatty acids% (except Lauric acid) which were increased when added to the irrigation water. Al - Husenawyia variety was higher in all parameters with the use of higher concentration of humic acid and zolfast when applied with irrigation water or foliar application. The three way interaction revealed no significant difference in stem diameter, vegetative dry weight, Ca%, fruit fresh and dry weight, TSS%, percentage of oil and unsaturated fatty acids (Linoleic and Myristoleic).8 - Results of electrophoresis analysis revealed that the use of the doubled recommended concentration of humic acid and zolfast with irrigation water participated in building higher protein molecules in fruits to both cultivars. While the double recommended concentration of humic acid and zolfast did not show this trait when foliar applied.

Abstract: Three experiments were conducted on two cultivars of sweet pepper Capsicum annuum L.; Flavio F1 and California wonder, to study the effect of seaweed extract and amino acids mixture and their combination on some vegetative and reproductive parameters, and some physical and qualitative characters of fruits. In addition, the chemical composition of leaves and some anatomical characters of stems were also evaluated. Furthermore, the effect of some treatments on genetic variations in both cultivars were studied. The field experiments were carried out at the fields the College of Agriculture/Al - Qadisiya University. The experiment was started at 18 - 1 - 2013 and ended at 3 - 7 - 2013. Seaweed extract, Basfoliar Kelp SL, was used at two concentrations; 3 or 6 ml. L - 1 in addition to control treatment (distilled water only). Also, a mixture of amino acids was used at two concentrations; 400 or 800 mg. L - 1 in addition to control treatment. Spray with the two substances was done in the early morning. The treatments were designed as a factorial experiment with two factors (3X3) in a randomized complete block design with four replications. The vegetative characters measured included; plant height, number of branches, percent of dry weight of shoot and root, and leaf chlorophyll content. Also, nitrogen percent, phosphorus and potassium content in leaves and roots was determined. The flowering and yield characters included; total number of flowers per plant, fruit set percentage, and total fruit yield per plant. In addition, weight, size, diameter and fruit length were measured. Vitamin C, total phenols, TSS, total sugars, alkaloids percent and the capsicin were measured in fruit juice. The anatomical characters of plant stem were included; epidermis, cortex and vascular bundles thickness, diameter of vascular units and pith thickness. The laboratory experiment was carried out during the period from 2 - 9 - 2013 till 16 - 10 - 2013. Spray with the two substances and their combination, at the same concentrations as used in the field experiment, was done on plants at the true leaves stage. The experiment was design as a factorial experiment with two factors in completely randomized design with four replications. The chemical characters measured in leaves included; content of auxin and gibberellin like substances, activity of catalase and peroxidase enzymes, amino acid content in addition to protein and sugar percent. Also, the genetic variation and genetic distance degree due to some treatments compared to control treatment using the RAPD with five primers was studied. The results were as the following : 1. Using seaweed extract and amino acids mixture, especially at the higher concentration, caused a significant increase in all vegetative characters measured for the two cultivars. 2. There were a pronounced increase in nitrogen percentage in plant shoot and root as the concentration of the treatments increased in both cultivars. 3. Increasing the concentration of the two factors caused an increase in phosphorus content in plant shoot of both cultivars. In roots, the use of the higher concentration of seaweed extract increased phosphorus content in Flavio F1 cultivar only. on the other hand, there was no significant effect on the mineral content in California wonder cultivar. Also, there was no significant effect on the phosphorus content in both cultivars due to the use of the two concentrations of amino acids and the combination of the two factors. 4. The use of seaweed extract caused a significant increase in potassium content in the shoots of the two cultivars. Also, the two concentrations of the amino acids caused an increase in the mineral content in shoots of the Flavio F1 cultivar only, while there was no effect in the California wonder cultivar. In roots, there was a significant effect due to the use of seaweed extract on potassium content, while there was no effect due to the use of the amino acids in Flavio F1 cultivar. In California wonder cultivar, no significant increase in potassium content was recarded in roots due to the use of all concentrations. 5. Seaweed extract and amino acids extract concentrations caused significant increase in total flowers number, fruit set, number of fruits per plant, plant yield and the physical characters of fruits, where the higher concentration of the two substances used gave highest values of fruit diameter, weight and size in both cultivars. Fruit length was not affected in Flavio F1 cultivar only. 6. The use of the two substances caused pronounced increase in TSS, sugars, vitamin C and phenols in the fruit of the two cultivars. Also, The use of seaweed extract had no effect on total alkaloids in Flavio F1 cultivar. While the amino acids mixture at the two concentrations increased alkaloids percent in fruit of the two cultivars. Also, there was a clear increase in the active ingredient (capsicin alkaloid) as the concentrations of the two substances used increase. 7. Both substances increased the auxin like substances in leaves of the two cultivars. The gibberelline like substances did not affect due to the use of seaweed extract of either cultivars. Amino acids had no significant effect. 8. The use of seaweed extract and amino acids mixture and their combination caused a significant increase in catalase and peroxidase activity in leaves, except the activity of peroxidase in leaves of California wonder cultivar which not affected by the seaweed extract. 9.Total free amino acids content and protein percent increased as the concentration of the two factors increased. Also, seaweed extract had significant effect on the percent of the total sugar. Amino acids treatments had no effect on sugar percent. 10.Using seaweed extract or amino acids caused an increase in epidermis and cortex thickness and size of vascular bundles of stem of both cultivars. 11.The use of seaweed extract, especially at the higher concentration, had significant effect in increasing the diameter of vascular units, while there was no effect due to the use of the amino acids. 12.There was a negative effect of the seaweed extract on pith thickness due to the use of the seaweed extract. on the other hands, the amino acids treatments caused an increase in stem pith. 13.The combination between seaweed extract and amino acids treatment had significant effect on most of the morphological, physiological and anatomical characters studied for both cultivars. 14.Increasing concentrations of seaweed extract and amino acids mixture or their combination caused an increase in DNA and RNA content in leaves of the two cultivars. The increase was greater at the higher concentration of both substances used. 15. Treatment with some concentrations of seaweed extract and amino acids and their combination produced plants with genetic variation as compared to the control plant using RAPD technology with five primers. The variation ranged from 13.04% using OPB - 9 primer to 33.33% using OPB - 4 and OPB - 11 primers in Flavio F1 cultivar.

Abstract: ا جريت هذه التجربة في قسم علوم الحياة / كلية العلوم / جامعة الكوفة في محافظة النجف الاشرف وتضمنت مرحلتين : الاولى زراعة البذور لغرض قياس نسبة الانبات للمدة من 1 / 8 لغاية 8 / 8 / 2011 وانتاج الشتلات للمدة من 15/8/2011 ولغاية 14 / 9 /2011 في حقل خاص لانتا | This experiment was conducted in the Department of Biology, College of Sciences, University of Kufa in Al - Najaf Al - Ashraf province. It included two periods : the first was seed sowing to measure germination percentage from 1 - 8 till 8 - 8 - 2011, and transplants production from 15 - 8 - 2011 till 14 - 9 - 2011 in a private farm for vegetable transplants production. The second was transplanting in an open field belongs to Plant Production Department/Kufa Technical Institute from 15 - 9 - 2011 till 17 - 1 - 2012 to measure plant growth parameters and curd cauliflower production cv.solid snow in harmless environment techniques. The experiment was adopted as factional experiment. The treatments were distributed according to Randomized Complete Block Design (RCBD) with four replicates. The experiment included the study of two factors : the first, was five magnetic intensities for treating waters magnetically (0; 500; 750; 1500 and 2500 Gauss) by means of dipolar magnetrons. The second was three quantities of plant organic manure(rice residues).i.e.(0, 2.5 and 5.0 kg/furrow) with a length of 6.5 m. and their interactions on growth and production the yield of cauliflower, cv.solid snow. Duncan's Multiple Range Test (DMRT) was used to compare means at probability of0.05. Correlation and regression coefficient were also used to evaluate the relationships between studied parameters and time. Vegetative growth parameters that are measured were : plant leaf number ; stem height; stem diameter; plant leaf area; leaf fresh and dry weight; stem dry weight; plant shoot fresh and dry weight. Flowering parameters were : curd fresh and dry weight and curd diameter. The results could be summarized as following : 1. Water chemical analysis showed that irrigation with magnetized treated water had an effect on physical properties, nevertheless, was more or less affected ions components. 2. The use of magnetized treated water in irrigation resulted in an increase in germination percentage of cauliflower seeds cv. Solid snow.The highest germination percentage was obtained from magnetic intensity of 1500 Gauss in both experiments, laboratory and field that reached 71.14 and 65, 62%, respectively on the base of Arc Sin. 3. The use of magnetized treated water in plant irrigation at all the used intensities resulted in an early emerged curd cauliflower by 15 days compared with control treatment plants. 4. 750 gauss magnetized treated water achieved at age of 138 days from transplanting, the highest plant leaf area mean is (4836.2 cm2) with percentage increase of 51.7% compared to control treatment plant leaf area (3188.3 cm2).That effect was reflected on curd weight. 5. 1500 and 2500 Gauss magnetized treated water treatments at earlier ages increased the values of vegetative growth parameters which reflected its effect on flowering growth parameters by shorter time of curd irritation, compared with the effect of 500 - 750 Gauss at earlier ages , which are in spite of its late effects produced at 150 days old from transplanting particularly 750 Gauss the highest mean of curd fresh weight. 6. 750 Gauss magnetized treated water achieved the highest yield reached 22.2 ton/h. which differed from that productivity gained from control treatment plant(9 - 29 ton/h.) with percentage increase of 138.8%. 7. Organic plant manure addition at both quantities(2.5 and 5.0kg/furrow) resulted in an increase in both vegetative and flowering growth parameters compared with untreated plants. 5 kg/furrow treatment produced the highest means compared to control treatment particularly at the age of 138 days in all vegetative growth parameters. 8. The addition of 5 kg/furrow at age of 150 days produced the largest curd fresh weight 918.4 g. and diameter of 17.2 cm which statistically differed to compared plant treatment that produced 506.0 g. and 13.3 cm. for curd fresh weight and diameter at the same age respectively. 9. 5 kg/furrow organic manure addition resulted in a highest productivity of 21.6 ton/h. compared to that of control treatment of 11.9 ton/h. with an increase of 81.5%. 10. Interaction between irrigation water magnetically treated with 750 Gauss and addition of (organic manure with 5 kg/furrow) at the age of150 days resulted in the highest curd fresh weight of 1292.9 g. with curd diameter of 20.3 cm. compared to that plant of control treatment produced curd fresh weight of 292.5 g. and 11.0 cm. diameter. This interaction also produced 30.3 ton/h. for (750 Gauss×5 kg/furrow) compared with the productivity of control treatment plants that gave 6.86 ton/h. with percentage increase of 341.6%
