چکیده انگلیسی
â¶Drought treatment significantly reduced net photosynthesis rate (A) and transpiration (E), but increased chlorophyll a (chla), carbon isotope (δ13C), endogenous abscisic acid (ABA), malondialdehyde (MDA) and hydrogen peroxide (H2O2) contents, and guaiacol peroxidase (POD) and catalase (CAT) activities. ⶠThere was an apparent alleviation of drought effects by shade, as indicated by the lower relative growth rate, and chlorophyll, MDA and H2O2 contents, and increases in indoleacetic acid (IAA) and reduced glutathione (GSH) contents. ⶠThe exogenous ABA application under shade induced protective effects on drought-stressed seedlings, as visible in MDA, A, stomatal conductance (gs), E, δ13C, ABA and IAA values. ⶠOur results suggest that seedlings of Cotinus coggygria are more sensitive to drought under full-light than under shade.
