Abstract:
Taking no light stress shading as the control,the influence on the chlorophyll relative content,osmoticum,protective enzyme activity,chlorophyll fluorescence parameters and cell structure characteristics of annual ‘Hongyang’ kiwifruit container seedlings were investigated under single-layer membrane shade (70% transmittance),two-layer membrane shade (45% transmittance),and three-layer membrane shade (25% transmittance) in this study.The results showed that single-layer,two-layer membrane shadow made container seedlings grow stronger,including chlorophyll relative content,concentration of glutathione (GSH) as well as the activities of peroxidase(POD),catalase(CAT) and superoxide dismutase(SOD)were significantly increased compared to the control,while the concentrates of MDA significantly decreased;the maximum photochemical efficiency of PSⅡ(Fv/Fm),PSII potential activity(Fv/Fo),electron transport rate(ETR),photochemical quenching (qP) increased,while non-photochemical quenching (qN) decreased compared with the control;each physiological index of container seedlings between the control and the three-layer membrane shade were not significant.Therefore,moderate summer shadow treatment could promote the growth of ‘Hongyang’ kiwifruit container seedlings.
