Abstract: (5079 Views)
As other crops, oilseed rape (Brassica napus L.) is severely affected under drought conditions. The mechanisms which reduce damages caused by oxidative stress have important roles in resistance of plants to drought stress and antioxidant enzymes have primed importance in this regards. In this factorial experiment 9 oilseed rape genotypes were compared under 3 stress levels (FC, 75%FC, 50%FC) in greenhouse of Agricultural College at Shiraz University. Under drought stress treatments, the activities of Superoxid Dismutase, Peroxidase, Ascorbic Peroxidase, Chlorophyll ،Cartenoid were increased. Drought stress increased the chlorophyll content of genotypes and it seems this increased in drought conditions affects plant leaf area. were increased the intensity of stress effects on The cholorophyll content and antioxidant enzyme activeties of SLM046 and Licord were increased due to increase in drought stress levels and consequently they had higher drought tolerance compared to the other ones. Modena was the most sensitive compared to the other genotypes.
