The goal was assess the effect of water stress, foliar application of proline and their interactions on characteristics morphological, physiological and nutritional status of three genotypes of maize namely : Serour, 5018, and Baghdad - 3.The characteristics included root's volume, root's length, root's diameter, root's dry weight, plant height, leaves number, leaf area, shoot dry weight, root/shoot ratio, absolute and relative growth rates and content of chlorophyll and proline in the leaves. The nutritional status included, the concentration, the contents and the rates of absorption and transport of N, P, K, Ca and Mg.In addition to the molecular study which included the technique of Random Amplified Polymorphic DNA (RAPD) DNA. A Factional experiment within Completely Randomized Design (C.R.D.) was adopted i.e. three genotypes of maize namely : Serour, 5018, and Baghdad - 3, proline (0, 50, 100 and 150) mg. L - 1 and two levels of field capacity (50 and 100) % with three replicates in a total of 72 experimental units.Means were compared using the least significant difference (LSD) at 0.05 probability level. Results could be summarized as follow : 1 - Genotypes significantly differed in the studied traits.The cultivar 5018 gave the highest values of root's volume, root's length, root's diameter, root's dry weight, plant height, and root/shoot ratio for spring and fall cultivations.The same cultivar gave higher values of P%, Ca%, Mg% in roots and the content of N, P, K, Ca and Mg in roots, rates of absorption and transport of N, P and Ca in spring and fall cultivations.Leaves P%, Ca% and Mg %, leaves Mg content and absorption and transport of Mg in fall cultivation. on the other hand, Serour cultivar give higher values of leaves number, leaf area, shoot dry weight, absolute and relative growth rates, content of chlorophyll and N% in root in spring and fall cultivation. P% in leaves in fall cultivation, leaves K% in both cultivation, content of N, P, K and Ca of shoot in both cultivations, shoot's Mg content of shoot in fall cultivation, content of N, P, K and Ca of shoot in both cultivation and Mg content of shoot in fall cultivations. Baghdad - 3 cultivar give higher values of proline content, Mg% in roots in both cultivations, shoot Mg% in fall cultivations, absorption and transport rates of K in fall cultivation, transport rate of Ca in spring and fall cultivations and absorption and transport rates of Mg in fall cultivation. 2 - Apart from Ca% of root in spring and fall cultivation, the proline markedly influenced all the rest traits where 100 mg. L - 1 proline gave the highest values compared to control treatment (i.e. 0 proline) that gave the lowest values. The proline at 50 and 150 mg. L - 1 gave intermediate values for all studied traits. 3 - Apart from some cases, 100% field capacity treatment gave higher values of most studied parameters. The field capacity of 50% gave higher values of N% and K% in roots and leaves, the content of N and K of roots and shoots and rates of absorption and transport rates of K in spring and fall cultivations. on the other hand, there was no effect of field capacity on Ca% of roots and shoots in spring and fall cultivation and Mg% of roots in spring cultivations. 4 - Bi and Tri interactions effect was profound on most studied characteristics. 5 - Through molecular study that including isolation of DNA in leaves of maize , a quantity of DNA ranging between 150 - 290 nano - gram / ?l with 1.8 - 1.9 purity was obtained. The differentiation of (RAPD) DNA was analyzed in order to prepare the finger print of maize genotypes. Six primers were tested (OPA - 09, OPA - 11, OPA - 13, OPC - 12, OPD - 20 and OPN - 16). The primers revealed different multiplication products between genotypes.The least value of genetic distance was 0.4103 between 5018 and Baghdad - 3genotypes, while the highest value of genetic distance was 0.7932 between Serour and 5018 genotypes.Data analysis revealed that these genotypes are divided into two main groups namely : group included 5018 and Baghdad - 3 genotypes, and group included Serour genotype only.

المستخلص: 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. In California wonder cultivar, the variation ranged from 4.35% using OPB - 14 primer to 73.33% using OPB - 5 primer.
