Abstract

Abstract: The photosynthetic physiological characteristics of Dactylis glomerata L.were measured under water stress.And the results showed:the net photosynthetic rate and transpiration rate of all four Dactylis glomerata L.showed two peaks on the curves of diurnal changes,and all witnessed obvious phenomena in midday depression of the two afore-mentioned rate.With aggravation of water stress,the net photosynthetic rate,transpiration rate,stomatal conductance and chlorophyll decreased dramatically,compared with ZXY04P-239,the net photosynthetic rate,transpiration rate,stomatal conductance and chlorophyll in the leaves of ZXY04P-201 decreased slowly.Chloroplast lamellar structure disordered,and lamella number decreased.Meanwhile,the result also showed that,stomatal restriction was the main factor of the net photosynthetic rate′s decrease in the leaves of 4 Dactylis glomerata L.when stress in slight water stress and the non-stomatal restriction was the main factor of the net photosynthetic rate in the leaves of 4 Dactylis glomerata L.when stressed in medium water stress and serious water stress.
