铝胁迫对不同品系油茶生长的影响
Effects of aluminum stress on the growth traits of different varieties of Camellia oleifera
摘要
Abstract
To investigate the effects of aluminum stress on the growth of different varieties of Camellia oleifera,this study selected one-year-old Camellia oleifera,Camellia osmantha,Camellia nanyongensis,and Camellia vietnamensis seedlings as research subjects.Different concentrations of aluminum stress(0,200,400,600,800,1 000,1 200 mg/L)were set,and the height increments,diameter increments,root length increments,and biomass increments of the 4 types of Camellia oleifera seedlings under different aluminum stress concentrations were measured.The results showed that:(1)both Camellia osmantha and Camellia oleifera seedlings exhibited strong tolerance to aluminum stress,while Camellia nanyongensis seedlings showed relatively weak aluminum tolerance;(2)when the aluminum concentration was≤600 mg/L,the increments of plant height,stem biomass,leaf biomass and total biomass increased significantly;when the aluminum concentration was≥1 000 mg/L,the plants showed symptoms such as yellowing and curling of leaves,and retarded growth;(3)when the aluminum concentration was≥1 200 mg/L,the leaves of the plants turned yellow and fell off,or even died,and Camellia nanyongensis showed more obvious symptoms.Overall,low concentrations of aluminum promote plant growth,whereas high concentrations inhibit root elongation and even damage root cells,ultimately leading to plant death.关键词
