Abstract:
Taking the seedings of Salin integra cv.‘Hakuro Nishki’ as test material，using the gradient of water stress method，the effect of the different soil water contents on the photosynthesis fluorescent parameters of Salin integra cv.‘Hakuro Nishki’ were studied.The results showed that flooding accelerated the growth of plants after treated for 23 days，which was embodied in the increasing of chlorophyll content，Fv′/Fm′，ETR，qP and net photosynthetic rate，while the change of Fv/Fm and Fo was not obvious.The drought stress and the moderate stress suppressed the growth of plants，which were embodied in the increasing of Fo，the decreasing of chlorophyll content，Fv/Fm，Fv′/Fm′，ETR，qP，photosynthetic rate，and the plants of the drought stress were dead after treated for 13 days,but the plants of the moderate stress were dead after treated for 20 days.
