Abstract:

The effect of water stress on the Trachelospermum jasminoides was tested by the method of gradient of water in soil. The results showed that flooding suppressed the growth of plants after treated for 51 days, which was embodied in the decreasing of Fv/Fm, Fv'/Fm', ETR, qP and net photosynthetic rate, while the change of Fo was increased. The drought stress and the moderate stress suppressed the growth of plants, which were embodied in the increasing of Fo, the decreasing of Fv/Fm, Fv'/Fm', ETR, qP, net photosynthetic rate. The plants of the drought stress were dead after treated for 24 days and the plants of the moderate stress were dead after treated for 38 days.
