Pb^2＋胁迫对桐花树碳代谢相关生理因子的影响
Effects of Pb^2＋ Stress on Some Physiological Characters of the Carbohydrate Metabolism of Aegiceras corniculatum
摘要
Abstract
Some related physiological characters of the carbohydrate metabolism of Aegiceras corniculatum under Pb2＋ stress were researched.The results showed that Aegiceras corniculatum had a strong resistant to Pb2＋ stress and the carbohydrate metabolism was affected by both the duration and the concentration of Pb2＋ stress.It showed that the activities of Hill reaction and the content of chlorophyll in the seedlings were increased when the Pb2＋ concentration in the cultivation soils rose to 500 mg/kg.However,the factors mentioned above showed a significant decrease with a higher Pb2＋ concentration as well as a longer duration of the stress.Experiments showed that chlorophyll a was more sensitive than chlorophyll b to Pb2＋ stress,and the Hill reaction activity of the plants showed more sensitivity than that of chlorophyll content for the Pb2＋ stress.Under the range of 500 ~ 2000 mg·kg-1 Pb2＋ stress,amylase activity increased with the Pb2＋ concentration.The amylase activity of the samples treated with Pb2＋ for 15 days was higher than that of the samples treated for 3 days.However,the amylase activity was significantly decreased when the Pb2＋ concentration reached to 3000 mg·kg-1.关键词
