Abstract


The effect of CdCl2 on the respiration, ATPase activities in PM, the changes of bioluminescence, NO synthesization, the protecting effects of CaCl2 and NO against CdCl2 in leaves and and in roots were studied using annual seedlings of Kyoho （Vitis vinifera L.×V. labrusca L.cv. kyoho） grape as materials. Results were as follows:1 CdCl2 treatment significantly induced accumulation of MDA and the increase of the membrane penetrability in leaves and roots, it also induced the activities of the activities of CAT, POD and SOD.2 0.5 mmol·L-1CdCl2 significantly inhibited the root activity, induced the total respiratory intensity and cyanide respiration rate, higher CdCl2 became inhabitation. 0.01 and 0.05 mmol/L CdCl2 induced Ca2+-ATPase activity, H+-ATPase activity was inhibited in plasma membrane （PM）. ATP contents of seedling firstly increased then decreased.3 UWL, fluorescence intensity of seedling leaf firstly increased then decreased. Phosphorescence intensity gradually rose as CdCl2 concentration increasing,4 0.5 mmol/L CdCl2 induced NO （nitric oxide） generation. The NO detected in Kyoho leaf appears to be NR-dependent, the two synthetic pathways of NO demonstrated may inhibit each other under conditions of Cd stress.5 The application of 0.5 mmol·L-1 CaCl2 significantly inhibited the increases of MDA and H2O2 content and electrolytic leakage of PM caused by CdCl2 treatment, and decreased the inhibition of CAT activity, respiratory rate and the activity of H+-ATPase and Ca2+-ATPase in PM under CdCl2 treatment.6 The application of 0.05 mM sodium nitroprusside （SNP, NO donor） markedly stimulated the activity of CAT, inhibited the increases of MDA content and the relative conductance under CdCl2 stress, and reduced the inhibition of respiratory intensity, H+-ATPase and Ca2+-ATPase in PM by Cd.
