摘    要:对锥栗幼苗进行不同程度水分胁迫研究 .结果表明 :水分胁迫使锥栗叶片相对含水量、超氧物歧化酶和过氧化氢酶活性下降 ,过氧化物酶活性上升 ,质膜相对透性和丙二醛含量增加 .叶面喷施 1 0 -4 mol/L 6- BA可以减缓水分胁迫条件下超氧物歧化酶和过氧化氢酶活性的下降 ,提高过氧化物酶活性 ,降低丙二醛和脱落酸含量 ,从而减轻了水分胁迫下活性氧对膜的伤害作用

关 键 词:锥栗幼苗  水分胁迫  保护酶  丙二醛  6-BA  ABA

Abstract:The effect of water stress in different degree on Castanea henryi seedling were studied in this paper Under water stress, the relative water content, superoxide dismutase(SOD), catalase(CAT) activities in leaves of Castanea henryi seedling were decreased, and the activity of peroxidase(POD), the relative plasmamembrane permeability and the contents of malondildehyde (MDA) were increased SOD,CAT and POD activities in the leaves treated with 6 BA were increased, and the contents of MDA and ABA in leaves were decreased Thus 6 BA reduced the damage of activated oxygen on membrane by water stress
Keywords:Castanea henryi seedling  water stress  protective enzyme  Malondialdehyde  N6  Benzyl adinine  Abscisic acid
