Effect of drought stress on germination, chlorophyll and carbohydrates contents in Triticum aestivum

Abstract EN

This study was conducted to determine the effect of water stress on germination , chlorophyll a, b, total chlorophyll and carbohydrates content in Triticum aestivum , five concentrations of PEG were used (100 , 200 , 300 , 400 , and 500 mg/l) in addition to control ( distilled water ).

Results of analysis of variance showed a significant decrease in germination in contrast with control and decrease in chl a , b , total chl and carbohydrates in low levels of drought stress , but in high levels of drought stress (400 and 500 mg/l ) its found a significant increase in chl a , b , total chl and carbohydrates contents in contrast to control.
