Abstract
The present experiment has been conducted to study the effects of different water conditions on the physiological characteristics of cassava leaves.Variety Huanan 205 was used as experimental material with four treatments,viz.,(A) normal water supply(CK),(B) mild drought,(C) moderate drought,and(D) severe drought.Physiological indices of stress resistance were measured during the cassava root formation period(May-July) and expanding period(July-September).The peroxidase(POD) and superoxide dismutase(SOD) activities in cassava leaves showed a rising tendency with the growth of cassava in the water stress treatments.Treatment D showed significantly higher POD and SOD activities compared to treatments A,B and C during root formation and expansion period.A drastic increase in POD activity has been observed in plants treated with treatment D.MDA and proline content and free water/bound water ratios in treatments C and D were significantly higher compared to treatments A and B.
