Abstract
Taking salt-tolerant cucumber (Cucumis sativus L.) variety ‘Xintai Mici’ as test object, a water culture experiment was conducted to study the effects of foliar spraying Ca(NO3)2 on leaf reactive oxygen species (ROS), antioxidant enzyme activities, antioxidants, and membrane proton pump activity of cucumber seedlings under the stress of 65 mmol NaCl·L-1. Under this stress, foliar spraying Ca(NO3)2 decreased the O-·2 production rate and MDA content, and increased the APX and DHAR activities, AsA content, AsA/DHA and GSH/GSSG ratios, and membrane H+-ATPase and H+-PPase activities significantly, suggesting that exogenous Ca could mitigate the oxidative damage induced by salt stress, and enhance the salt-tolerance of plants through up-regulating the plant antioxidant ability and ion compartmentation.
