【摘要】 本文对吉林省夏播小麦的子粒灌浆速度和发芽率进行了研究,结果指出:①子粒灌浆速度遵循y=ae^b/x函数,灌浆过程持续进行。②夏播小麦表现明显的休眠现象,休眠程度随温度的降低、光照长度的缩短而加深。③夏播小麦开花16d后的种子发芽率达95％以上。更多还原

【Abstract】 The results showed that the kernal filling rate followed closely functiony=ae (b/x). Summer-sowing wheat have obvious dormant penomenon, the lower of temperature and the shorter of day. the deeper of dormancy. The seed germination percentage reached 95% after flower 16 day.更多还原
