10个羊蹄甲优良家系抗旱性研究
Drought Resistance of 10 Bauhinia purpurea Families
摘要
Abstract
Seedlings of 10 superior clones of Bauhinia purpurea were subject to naturally drought stress.Physiological indexes were measured at 0 d,3 d,6 d and 9 d,such as superoxide dismutase (SOD) activity,relative conductivity and chlorophyll content.The principal component analysis and system clustering analysis were adopted to comprehensively evaluate the drought tolerance capability.The principal component analysis indicated that clone NX07 had the strongest drought-tolerance capability,while LKY01 was poor in drought tolerance.Ten clones were classified into four categories according to their drought resistance capability:the strongest (NX07,NX05,DNS21,and DNS11),strong (DNS1),moderate (DNS34,NX08,NX04 and DNS16),and weak (LKY01) drought tolerance group.关键词
