A PRELIMINARY STUDY OF DROUGHT RESISTANCE WITH WATER STRESS IN SOME CULTIVARS OF SWEET POTATO

WANG ZHIHUAI HUANG JICHENG LI KUNPEI  
In the present study, we have observed the difference in physiological responses to soil water stress among four sweet potato cultivars, viz., Yusu 1, 813-19, Nongdahong and Xushu-18. Under soil water stress condition, the value of water potential in Yusu 1 relative to that of the check plot plants was the lowest and that of proline accumulation was high, yet the relative permeability of leaf cells increased the least. These results demonstrated that the osmotic regulative capacity and drought resistance of Yusu 1 are better than those of 813-19, Nong-dahong and Xushu-18. The free proline content in leaves was consistent with the above stated results under osmotic stress condition (15% PEG. hypertonic culture solution") . It was concluded that the osmotic regulative capacity and drought resistance of sweet potato cultivars were closely related with the proline accumulated in leaves.Thus the amount of proline accumulation in sweet potato leaves could be used as a sensitive parameter under water stress condition.
