In many kiwifruit growing regions, high temperature, drought and strong light often lead to leaf abscission and fruit drop, reduction of fruit yield.
猕猴桃是一种中等喜光性果树,在许多引种栽培地区因高温干旱强光危害而造成落叶落果,果实品质下降,产量和贮藏性降低,甚至导致植株死亡,严重影响其经济效益。
Compared to the results of low ligh treatment, strong light lowered significantly Fv/fm and ere (Fig.
莴苣叶绿体在强光处理下发生先抑制,主要表现为叶绿素荧光参数Fv/Fm和ΦPSⅡ降低;外源活性氧H2O2、O2·OH和1O2均能引起叶绿体PSⅡ光化学效率Fv/Fm不同程度的下降,其中以1O2影响最明显;H2O2在诱导叶绿体荧光猝灭过程中,引起荧光产量降低,而使qp、qN、ΦPSⅡ、KD上升;在H2O2诱导的叶绿体荧光猝灭过程中,Fe2+能使qN和KD低于对照;由于1O2的产生对PSⅡ反应中心造成了损伤,引起qp和ΦPSⅡ下降。
