摘要
依据水稻异交率的数学模型,对柱头外露、柱头活力、日花率分布等进行了定量的研究,克服了传统田间试验条件下试验处理与异交特性不易达到唯一差异的严重缺陷。文中还对异交特性的相关问题进行了讨论。
Stigma exposure rate (SER), stigma vigor and the distribution of daily flowering rate were quantitatively studied, using the mathematical models for out-crossing rate (OCR) in hybrid rice seed production, thus overcoming the shortcoming in traditional field experiments that the experiment treatments and the out-crossing characteristics are unlikely to realize 'only one difference.' Some problems concerning out-crossing characteristics are discussed.
