- 摘要:
- 以‘辽引一号’西瓜品种为试材，于三叶一心期用0（CK）、0.01、0.05、0.10、0.50、1.00 mg/L的油菜素内酯（BR）喷雾处理，在温度（10±1）℃，光照100 μmol?m-2?s-1条件下胁迫，分析西瓜幼苗耐冷性的生理生化特性变化，以期筛选出提高西瓜幼苗耐冷性的最佳BR浓度。结果表明：通过油菜素内酯（BR）处理，可以显著降低西瓜幼苗冷害指数，提高SOD、POD和CAT活性，降低丙二醛、超氧阴离子自由基含量，其中0.10 mg/L的BR喷施效果最佳。
- Abstract:
- Watermelon variety ‘Liaoyin No.1’ were treated at the age of three leaves by spraying brassinolide in the concentration of 0(CK),0.01,0.05,0.10,0.50,1.00 mg/L,and then were stressed under temperature (10±1)℃ and light 100 μmol?m-2?s-1.In order to improve chilling resistance of watermelon seedlings,the physiological and biochemical characteristics of watermelon seedlings were measured to screen a optimum concentration of brassinolide(BR).The results showed that the best seedlings growth was observed under the treatment 0.10 mg/L of BR,which could reduce the chilling injury index significantly,increase the activities of superoxide dismutase (SOD),peroxidase (POD) and catalase (CAT) and reduce the content of malondialdehyde (MDA) and superoxide anion radical.
