摘 要 ：用800个中国水稻品种试验的结果指出:不同地区原产的品种不但对光照长度的反应特性不同,而且在短日照下的生育期也不同。这种特性称为短日生育性。北方的品种短日生育性较小;南方的品种从小到大都有。品种成熟期的早晚是其光照长度反应特性和短日生育性在一定环境条件下的具体表现,改变环境条件时,早晚熟的顺序随之改变。对光照长度反应弱的品种一般产量变化小,适应力大。试验结果得出各地区品种的光长反应特性和短日生育性。

Abstract:This work was conducted in 1955-1956 at Nanking (32°03 N ),China.800 rice varietiesnative to China were collected and sowed under the day-length of 9.5,11.5,12.5,13.5,and 18hrs.and natural day-length as control.Bamboo frames with black oil-cloth were used to shutoff day-light for short-day treatments.While electric lamps were used to lengthen naturalday-length for long-day treatments.Seeds soaked with water for 36 hours and vernalized at25℃ for 12 days and then,sowed on May 20:It was demonstrated that even ...
