المستخلص: 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.

المستخلص: This study was conducted in Biology Department - College of Science - University of Al - Qadisiya that included pot experiment from the period of 1/4 to 1/8/2013, to assess the effect of water stress, foliar fertilizer (Foltron) and organic fertilizer (Azomin) on growth of Adhatoda vasica (L.) Nees and Its Content of Some Active Ingredients. Laboratory experiments were also done from the period of 1/8 to 1/3/2014, to determine the activity of leaves and roots extracts that resulted from plants of pots treatments to inhibit growth of some bacteria genera causing Dental Caries i.e. Staphylococcus aureus, Streptococcus mutans and Streptococcus pneumonia.A pot experiment included seventy two transplants (age of one month and 8 cm height) that were transplanted in plastic pots (one transplant per pot) in 1/4/2013. Pots were filled with sandy soil and peatmose 2 : 1 v/v. Plants Irrigated with two levels 50 and 25% of field capacity. Foliar fertilizer was used at three concentrations of 0, 3 and 6 ml/L that sprayed twice on plant shoot till complete wetness during 15/4 and 1/6/2014. Organic fertilizer was also used with irrigation water at three concentrations of 0, 4 and 8 ml/L twice on 1/5 and 15/6/2014. The design of the experiment was Randomized Complete Blocks Design (RCBD) in a factorial arrangement (2×3×3) with four replications per each treatment. Revised Least Significant Difference (RLSD) was used to compare treatment means at probability 0.05 level when treatment effect was significant.Results of pots experiment were as follows : 1 - Increasing water stress level caused a significant decrease in the most characteristics of vegetative and root growth except for stem internode and root lengths, while increasing in concentration of foliar and organic fertilizer gave the opposite effect of water stress.2 - Water stress caused a significant decrease in leaves content of total chlorophyll and nutrient elements N, P, K, Mg and protein percentage, while foliar and organic fertilizer caused a significant increase on the above characteristics.3 - Water stress caused a significant increase in proline percentage and Vit.C. and Vasicine and Vasicinone alkaloids, while foliar and organic fertilizer caused a significant decrease in proline percentage and Vit.C. and a significant increase in Vasicine and Vasicinone alkaloids.4 - The treatment of plants that were subjected to the water stress via foliar or root fertilizing or both of them caused a significant increase for most of vegetative and root growth characteristics, total chlorophyll, nutrient elements, protein percentage and Vasicine and Vasicinone alkaloids.5 - The treatment of plants that were underwent to the water stress via foliar and root fertilizing caused a significant decrease in proline percentage, Vit.C. and stem internode and root lengths.6 - The interaction of the three studied factors gave a significant positive effect to rise alkaloids of plant.Laboratory experiments included picking fresh leaves and root of plants that dried aerial in a shade, and then extracted it via methanol alcoholic of 70%, it was detected for some chemical components of extract by using reagents. Bacterial genera were isolated from the surfaces of the teeth and cultured on the growth media, and it was diagnosed by the Vitek Compact 2 System Diagnosis. The activity test involved the impact of the alcohol extract for leaves and roots to the inhibition of bacterial growth by the agar well diffusion method on Muller - Hinton.The design of the experiment was Complete Randomized Design (CRD) in a factorial arrangement (18×3) with three replications per each treatment. Revised Least Significant Difference (RLSD) was used to compare treatment means at probability 0.01 level when treatment effect was significant.Results of laboratory experiment were as follow : 1 - Increasing extracts concentration caused a significant increase in growth inhibition of the studied bacterial genera.2 - plants extraction that of the combination of A2B3C3 included (25% water stress, 6 ml/L foliar fertilizer and 8 ml/L organic fertilizer) gave the highest activated inhibition for bacterial genera compared with plant other extraction for all tested bacterial genera.3 - The plants extracted that treated by combination A2B3C3 in concentration 150 mg/ml gave higher activated inhibition for Streptococcus pneumonia reached 25.307 ml compared with Amoxicillin that reached 36.167 ml, while the inhibited extracted root reached for the same treatment 16.060 ml (Table 37 and 38).4 - Plants leaf extract was the highest effective inhibition of bacterial compared to the roots extract.

Experiment included study three factors is the quality of irrigation water (river water or well water) - Main plot, wheat bread varieties (IPAA - 99, Rashid and Tamuze - 2) - Sub - plot and magnetic treatment to irrigation water four intensities is (0, 750, 1500 and 3000) Gauss - Sub - sub - plot. The Revised Least Significant Difference (RLSD) at 0.05 probability was used to compare treatment means, whenever treatments affects were evident.Results showed : 1 - Wheat plants irrigated with river water were superior in all parameters in forms of plant height, leaves number, leaf area, tillers number; productive and non - productive, root length, lateral root length of the plant, leaves content from total chlorophyll, dry weights for plant vegetative, phosphorus% in grains, grains weight of spike, spike number of plant and m2, weight of 1000 grain, plant yield of grains, m2 yield of grains, hectare yield of grains per hectare compare to plants irrigated with well water, which recorded the highest chemical content of grains from nitrogen, potassium, magnesium, protein and carbohydrates percentages. The percentage of flowering, spikes length, spikes grains number were superior in the beginning with the well water, were superior at the end with river water.2 - Magnetic treatment with irrigation water by 1500 gauss revealed that noticeable superior was obtained in most of plants vegetative and floral characteristics, while the chemical characteristics had increased with magnetic water treatment by 3000 gauss and yield characteristics treated with 750 gauss. The effect of magnetic water treatment on leaves content from total chlorophyll and magnesium percentage in grains was negative.3 - The majority of vegetative, chemical and productivity parameters was increased with Rashid plants cultivar compared to same parameters for Tamuze - 2 plants cultivar which superior than IPAA - 99 plants cultivar except number of leaves, tillers number and spike grains number which superior with IPAA - 99 plants cultivar.4 - The triple interaction between experiment all factors revealed a significant effect on magnetized river water at 1500 gauss in Rashid and Tamuz - 2 plants cultivars giving highest vegetative growth indicators average which increased on plant yield with low magnetic water treatment (750 gauss) to Rashid plants cultivars and medium strongly (1500 gauss) for Tamuz - 2 plants cultivars, while the characteristics of grains chemical content were superior with same plants cultivars but magnetized treatment well water at 3000 gauss.
