تراكم البرولين بإععتباره مؤشرا جزيئيا للتنوع الحيوي و التأقلم مع الجفاف عند الحبوب

Abstract

The present study was carried out with an aim of knowing the range of to adaptation of 25 genotypes of durum wheat (Triticum durumDesf.) the lack of water has through the accumulation of the proline which is considred like molecular r indicator of adaptation in the medium of growth under different levels of water alimentation like :50%, 37.5%, 25%, 12.5%, 6.25% of field capacity . The results of our study give us a variability between genotypes studied , which indicate more for biological diversity. This diversity is the physiological response of each variety on water stress application .I t will be used in durum wheat breeding.
