- 摘要:
- 以露地栽培的边沁班克木(B.benthamiana)、多刺班克木(B.spinulosa)、沼泽班克木(B.robur) 3种班克木的5年生植株为试材，采用隶属函数的方法，于不同季节通过对其生理生化指标的测定、分析，研究了不同水分条件下各植物抗旱性指标的变化特征和综合效应。结果表明：抗旱性强弱顺序为边沁班克木>多刺班克木>沼泽班克木；超氧化物歧化酶（SOD）活性、丙二醛(MDA)含量和可溶性蛋白质含量等指标可以较好地反映班克木的抗旱性。
- Abstract:
- Taking 5-year-old open cultivation seedlings of Banksia benthamiana，B.spinulosa，B.robur as materials，the change characteristics and synthetical effect of each plant drought tolerance index were studied under different water conditions by measuring and analyzing their physiological and biochemical indexes in different seasons，and membership functions method was used.The results showed that the drought tolerance of the 3 species of Banksia from strong to weak was as follow,B.benthamiana，B.spinulosa，B.robur.Indexes of the SOD activity,MDA content and soluble protein content could reflect the drought resistance better.
