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 study was conducted on six varieties of cucumber: Napleon, Ampres,
Sendian, Prence, Samara and Baladi. To study the responses of these varieties
to drought stress, on the seed germination and seedling growth under different
Polyethylen glycol
concentrations (0 control, 10 mM, 20 mM and 40 mM PEG).
The results of this research showed a some varieties to its tolerance to drought
stress. The varieties Ampres, Prence and samara showed more resistance to
drought stress. It s indicated with increasing seed germination and growth of
seedlings with the higher concentration of PEG in compared to another
varieties.
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).
