Rapeseed Morpho-Physio-Biochemical Responses to Drought Stress Induced by PEG-6000

Rapeseed is a valuable oil crop due to its high nutritious value and ample content. The current study provides comparative analysis of 24 cultivars better understand the performance predict adaptative mechanisms drought-tolerant drought-sensitive based on germination morphophysiological traits during early seedling stage using PEG-6000 simulated drought conditions. JYZ 158 FY 520 (tolerant cultivars) YG 2009 NZ 1838 (sensitive were selected further explore role osmolytes enzymatic activity in improving tolerance. This investigation illustrated that stress negatively influenced all studied cultivars; however, degree influence was different for each cultivar, suggesting their potential Moreover, osmoregulatory highly efficient tolerant compared sensitive cultivars. Additionally, showed higher chlorophyll lower malondialdehyde (MDA) contents versus under Higher tolerance coincided with osmolyte work had tolerance, might be significant germplasm resource breeding programs developing rapeseed.
