Abstract EN
A Sudy was conducted in controlled growth chamber, in the department of plant biology in faculty of science, Damascus university (Syria( (2016 - 2017(, to evaluate the response of six wheat genotypes (Cham1, Cham3, Omrabi5, Lahn, Jedara2 and Horani! for drought tolerance, based on some physiological and biochemical traits, which are genetically associated with drought tolerance.
Indeed, high values of relative water content were found in Cham1, Cham3, Jadara2 and Horani as a result of Somata closing and free proline (Prol.) and soluble sugar (Sug), accumulation under drought effect, they exhibited more lability of chlorophyll and integrity of the cytoplasmic membranes (CMS} to sustain cell elongation, where the leaf dry weight and DTI and GMP were significantly higher in the same varieties.
Whereas, the loweS values of relative water content (RWC) were noticed in Omrabi5 and Lahn2 because they hadn’t the ability to close efficiency their Somata.
Thus, almoS of genotypes could be classified as active osmo-regulating varieties, by accumulating compatible solutes (proline and/or soluble sugar) which maintain a good water balance relations within leaf tissues.
Chami is considered as the moS adapted local variety to drought Sress, and as a promising genetic material for some of the physiological and biochemical traits associated with drought tolerance.
The studied physiological and biochemical traits and drought indices DTI and GMP could be good criterion, in earlier growth stage, for selection of drought tolerant wheat genotypes, under controlled growth chamber.
