Abstract
Medical plant Purslane contain large amounts of material with extraordinary health benefits of Omega-3 fatty acids and monounsaturated fatty unique combination of vitamin C, beneficial effects on the circulatory system and the heart. Therefore, research into application attract moisture substance and organic fertilizer and chemical on yield of purslane (Portulaca oleracea L.) In Ahwaz conditions, a field experiment was conducted experimental field of Ramin Agriculture and Natural Resources University in Ahwaz, south-western of Iran, during 2011 growing season. Treatments were arranged as a split plat experiment in a randomized complete block design with three replications. The main plot involves Zeolites of 2 tons per hectare, Control plots without application of fertilizer, super absorbent material at the rate of 200 kg per hectare and subplots involving fertilizer treatments at six system cow manure system, Sheep manure system, poultry manure, Filter cake, Urea nitrogen fertilizer rate of 180 kg hectare and source of phosphorus, 150 kg of triple superphosphate and Control plots without the use of fertilizers. Zeolites and super absorbent the highest levels of plant dry weight, plant height and number of lateral branch had the highest. Application of chemical fertilizers, plant dry weight, plant height, number of secondary branches, chlorophyll a, b, carotenoids and protein significantly increased and Control manure treatment had the lowest levels of these traits. Treatment of cow manure, sheep and control has the highest percentage of oil and chemical fertilizer treatments had the lowest percentage of oil. The results indicate the possible use of chemical fertilizers and manure plus in boosting performance oleracea was with absorbent material.

Abstract
This study was conducted to evulate the effect of water stress on soluble carbohydrates, root and leaf proline, photosynthetic pigments, petal and seed yield of pot marigold genotypes. It was performed as split plots in randomized complete block design with three replications. Three irrigation regimes (35%, 60% and 85% of available soil water depletion) designed as main plot and nine pot marigold genotypes (Ahvaz, Tehran, Isfahan1, Isfahan2, Candy-man, Gitana, Zen-Gold, Isfahan3, Isfahan4) were evaluated as sub-plot in Ahvaz in 1394-95 growing seasen. The results showed the effect of irrigation regimes and genotype were significant on studied traits, petal and seed yield. Due to drought stress, the content of carbohydrates, root and leaf proline increased but RWC, carotenoid, chlorophyll a, b and a + b, petal and seed yield of genotypes decreased significantly. The results showed high correlation between soluble carbohydrate and leaf proline content with RWC and drought sensitivity index. Resistant genotypes had a highest content of soluble carbohydrates, leaf proline and carotenoid. Based on drought sensitivity index, "Ahvaz", "Isfahan2" and "Isfahan1" genotypes divided in drought resistant group, "Tehran", "Candy-man", "Gitana" in moderately resistant group and " Isfahan4", "Zen-gold" And "Isfahan3" in sensitive group. "Candy-man" and "Ahwaz" genotype produced the highest petal and seed yield, respectively, at all drought levels.

Abstract
In order to investigate the effects of priming methods on the improvement of seed germination indices and seedling growth of Lallemantia (Lallemantia iberica) under different salinity levels, two factorial experiments in a randomized complete block design were carried out in the seed technology laboratory of Agricultural Sciences and Natural Resources University of Khuzestan in 2018-2019. In the first experiment, five levels of seed priming including: Control, hydropriming (for 24 hours), gibberellic acid (100 mg.l-1 for eight hours), and solutes of potassium nitrate and sodium chloride (NaCl) (50 mg.l-1 for 6 hours) as the first factor and four levels of salinity stress, including 0 (control), 100, 200, and 300 mM of NaCl, as the second factor in four replications were examined. Also, a pot experiment was conducted to determine the effects of the studied treatments on some seedling growth indices in three replications. In general, indices of germination percentage, germination rate, radicle length, plumule length, emergence percentage, emergence rate, contents of chlorophyll a, b, carotenoids, and enzymatic activities of catalase and peroxidase were evaluated in this study. Results revealed that salinity stress, priming, and their interaction had significant effects on most of the studied traits. Also, increasing salinity concentrations led to decreases in all traits (except the activity of antioxidant enzymes). Generally, our findings showed that all seed priming treatments moderated the negative impacts of salinity stress and the application of NaCl could be a suitable treatment to increase the tolerance of Lallemantia seeds against high levels of salinity stress.
