描述了一种评价水稻（Oryza sativa L.）植物耐淹性的新方法。 一系列品种的反应与已知的田间表现差异相对应。 该方法 1) 允许快速有效地测定浸水耐受性，2) 允许在小型温室区域中筛选许多植物，3) 提供用于种子收集的优质植物的回收，4) 允许操纵许多环境变量以模拟自然浸水环境，以及 5) 使用简单、廉价、易于获得的设备。 用这种方法进行的生理研究得到了与田间研究相似的结果，并表明老植物的耐淹性有所提高；它随着深度的增加、温度的升高以及光照水平的高低而降低。 该系统非常适合在受控条件下快速评估水稻种质以及水稻耐淹机制的生理研究。
A new method is described for evaluation of submergence tolerance of rice (Oryza sativa L.) plants. Responses of a range of cultivars corresponded with known differences in field performance. The method 1) allows fast and effective determination of submergence tolerance, 2) allows screening of many plants in a small glasshouse area, 3) provides for recovery of superior plants for seed collection, 4) allows manipulation of many environmental variables to mimic the natural submergence environment, and 5) uses simple, inexpensive, readily available equipment. Physiological studies performed with this method gave results similar to those obtained from field studies and showed that submergence tolerance increased in older plants; it decreased with increasing depth, increasing temperature and with high or low light levels. The system is ideal for the rapid evaluation of rice germplasm under controlled conditions and physiological studies on the mechanism of rice submergence tolerance.
