تقييم أداء عدة أصناف من فول الصويا (Glycine Max L) تحت تاثير الإجهاد الجفافي في ظروف محافظة دير الزور
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.

This research was conducted during 2014 season at Miaar Shaker
plains in Tartous region, to study the effect of applied drought stress for
24 days in 4 growth stages of peanut crop, i.e., 1. Brunching stage, 2.
Flower initialing stage, 3. Pod form
ation stage, 4. Seed formation stage,
beside of control (full irrigation by 12 days intervals). And effect of
these treatments on some growth attributes and yield to peanut
genotype (Sahel).
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.
