摘要
本研究选取健壮无病空心莲子草(Alternanthera Philoxeroides(Mart.)Griseb.)植株作为研究对象,对其进行0 cm、10cm、20 cm和30 cm水淹胁迫观测,分析形态指标变化趋势和其对水淹胁迫梯度与胁迫时间的响应规律。
In the paper, the healthy and the free of disease plants of the Alternanthera philoxeroides ( Mart. ) Griseb are selected as the research object, and the different submergence stress gradient treatments of the 0 cm, 10 cm,20 cm and 30 cm experiment are observed. The change trend of morphological feature index, the response regularity in different submergence stress gradient and the tress time of the Alternanthera philoxeroides are analyzed.
