[Method]Through artificial simulation of drought stress environment,the changes of physiological indexes,such as content of proline,malonaldehyde,and reducing sugar in Yixing lily leaf and bulb were observed,when soil water content changed. [Result]The response to drought stress of the Yixing lily leaf was greater than that of the bulb,and the content of the proline and malonaldehyde was higher than that of the reducing sugar. [Conclusion]The leaves as an appropriate material for evaluation and analysis on drought resistance can better reflect the physiological responses of Yixing lily to drought stress. And the content of the malonaldehyde and that of proline are preferable indexes.展开更多
