The study has been conducted in region of Sweeda on the nursery of Era during the two seasons of 2008 and 2009 aiming at the morphological and physiological assessment of the seedlings of Amygdalus orientalis under different degrees of water stress in different altitudes on the Arab mountain, specifying the tolerance of those seedlings to that stress and defining the most tolerant seed sources to water stress in order to use them as grafting stocks.

The study was conducted in order to know the ability of Korschinskii Almonds and Orientalis Almonds to resistance of the drought stress using several levels of water irrigation (100, 75, 50 and 25%) from the field capacity, with several indicators (number of leaves, the thickness of the leaves, root growth). The results obtained showed not affected by the stock in the Korschinskii Almonds drought stress (255, 242, 220, 198 leaves), while the number of leaves that accompany the burning edges under the influence of drought stress in Orientalis Almonds (250, 130, 60, 12 leaves) at levels of irrigation water (100, 75, 50, 25%) of field capacity respectively.
The experiment was carried out during spring season 2016 to study the effect of foliar spraying treatment with Tecamin Flower 2.5 ml/L in comparison with distilled water, on growth of three hybrids of tomatoes at two different levels of irrigation (100 and 50 % of field capacity). Three sprays were conducted started from flowering with two weeks’ interval. The results showed that ‘Finenss’ hybrid had significant differences in plant height, branches per plant and leaves number per plant. ‘Hadeer’ hybrid had superiority in dry matter ratio and content of chlorophyll in leaves. Reducing the level of irrigation resulted in a significant decrease in plant height, total branches number, versus an increase in the leaves number per plant, total leaves area and the percentage of dry matter. The results showed that the treatment with Tecamin flower led to a significant increase in all indicators studied. The interaction treatments shoed that Hadeer hybrid irrigated in level 50 % and spraying of nutrient solution (Tecamin flower) had a significant increase in dry matter ratio and chlorophyll content in leaves. While the hybrid Finenss which irrigated in level 100 % with nutrient solution (Tecamin flower) had a significant increase in leaves number per plant and total leaves area.
In vitro rooting was significantly increased by adding indolebutyric acid (IBA) to medium and rooting was improved by adding ١,٠ g/L activated charcoal or ٠,١ g/L polyvinylpyrrolidone (PVP). Indoleacetic acid (IAA) (٠,٠ to ٤,٠ mg/L) was not effect ive for rooting except when used with ٠,١ g/L PVP. A ٩٥٪ survival was achieved when plants were acclimatized ex vitro. Such procedures could help significantly in clonally propagating bitter almond and conserving its germplasm.
This research on pepper crop conducted to impact water stress using three transactions water are: full irrigation (100% from water requirement), 0.75% of full irrigation, and 60% of full irrigation, has been designed experiment in a way random sectors full, use a variety of municipal plant peppers, and used drip irrigation method.
An experiment was conducted in Kharabo station which belongs to the faculty of agriculture, Damascus university during the growing season 2009 ! 2010, to evaluate the response of seventeen sorghum genotypes under water stress conditions during the flowering stage according to the randomized complete block design (RCBD), with three replicates.
