不同油茶幼苗在铝胁迫下的生理生化特性
The Physiological and Biochemical Characteristics of Different Camellia oleifera Seedlings under Aluminum Stress
摘要
Abstract
In order to study the response mechanism of Camellia oleifera to aluminum toxicity and screen aluminum-resistant varieties.Taking one-year-old seedlings of Camellia osmantha,C.oleifera,Nanrong C.Oleifera,and Luchuan C.oleifera as research objects,the physiological and biochemical responses of several C.oleifera seedlings under different concentrations of aluminum(Al)stress were studied.The results showed that the chlorophyll content in the leaves of C.osmantha Yihang,C.oleifera Cenruan 24,Luchuan C.oleifera and Nanrong C.oleifera seedlings decreased with increasing Al concentration and decreased significantly when the Al concentration was greater than 600 mg·kg-1;the malondialdehyde(MDA)content in the roots,stems and leaves of C.osmantha(Yihang),C.oleifera(Cenruan 24),Luchuan C.oleifera and Nanrong C.oleifera seed-lings increased with increasing Al concentration,and compared with the leaves,the MDA content in the roots and stems in-creased significantly;the superoxide dismutase(SOD)activity,peroxidase(POD)activity,catalase(CAT)activity and soluble protein in the roots,stems and leaves of C.osmantha(Yihang),C.oleifera(Cenruan 24),Luchuan C.oleifera and Nanrong C.oleifera seedlings all increased first and then decreased with increasing Al concentration,and decreased significantly when the Al concentration was greater than 600 mg·kg-1.关键词
