1α-NAA和UV-B辐射对栝楼幼苗光合色素及保护酶活性的影响显示文摘温室条件下研究 UV- B辐射 ( 0 .0 2 9J/( m2·s) )和外施 α-萘乙酸 ( α- NAA) ( 2 mg/L)对栝楼叶片光合色素及保护酶活性的影响。实验结果表明 :外施α- NAA,能提高栝楼幼苗叶片叶绿素及类胡萝卜素的含量 ,提高保护酶 SOD、CAT、POD、ASP的活性 ,细胞膜相对透性和膜脂过氧化产物 MDA含量相对稳定。UV- B辐射单独处理 ,则极显著地降低叶绿素 a的含量 ,叶绿素 b含量也呈明显地下降趋势 ,类胡萝卜素含量稍有下降 ,极显著降低栝楼幼苗叶片 SOD、POD、CAT、ASP活性 ,引起细胞膜相对透性明显增大 ,MDA含量显著增加。α- NAA与 UV- B辐射共同处理栝楼幼苗 ,与 UV- B辐射处理相比 ,叶绿体色素含量都有不同程度增加 ,而细胞膜相对透性、MDA含量则有不同程度降低 ,SOD、POD、ASP活性上升 ,CAT活性显著上升。以上结果暗示 ,UV- B辐射对生长的影响可能是 :( 1 )破坏光合色素而导致光合能力下降 ;( 2 )降低保护酶 SOD、POD、CAT、ASP活性 ,导致膜脂过氧化 ,膜结构遭到破坏 ,膜透性增加。而外施α- NAA,能部分减轻由增强的 UV- B辐射对栝楼幼苗造成的这种伤害 ,其原因可能是 α- NAA提高了保护酶活性 ,维持了活性氧产生与清除之间的平衡 ,即是维持了膜结构的稳定性。可见 ,α- NAA能增加栝楼对 UV- B辐射的抗性。刘芸 钟章成 Marinus J.A.
