摘要： 本文研究了7个不同类型水稻品种发育过程中对16小时长日与10小时短日不同组合处理反应的特性。根据长短日照不同组合对生育期的影响和长日处理不同天数后达到抽穗所需短日天数的不同,观察到晚籼品种对长日反应有3个不同特点的时期,即“长日促进期”,“长日抑制期”和“长日补偿期”。几个早中籼品种没有“长日抑制期”。2个粳

Abstract: The response of different rice varieties to 16-hour long day and 10-hour short day was studied.According to the effect of long and shortdaylength on growth duration,the response to long day in late maturingrice varieties could be divided into three phases,namely“long day ac-celeration phase”(LAP),
