The Effect of Water Stress on the Physiology of Vinca major 'Variegata'

Abstract:

The effects of water stress on the two year old Vinca majorVariegata were tested for proving the irrigation guidance for its application in the garden. The results showed that the water flood and the drought stress suppressed the plant growth. After treated with flooding for 13days, the qP, ETR, Fv'/Fm' and net photosynthetic rate were decreased, but the qN were increased and the plants were dead. The mid drought stress (the water content of soil were between 20 percent and 30 percent) slightly affected the growth of plant, which embodies in the slight decline of chlorophyll, qP, ETR, Fv'/Fm', Fv/Fm and qP, the ascend of net photosynthetic rate. Drought Stress badly affected the growth of plant, which embodies in the decline of chlorophyll, qP, ETR, Fv'/Fm', Fv/Fm, qP and net photosynthetic rate. The best irrigation for plant was the water content of soil between 20 percent and 30 percent, which does not affect the ornamental value of Robinia pseudoacacia and save the irrigation water. So the application of V. majorVariegata should avoid in the place for over 13 days water flood.
