油菜是总状无限花序,始花以后便进入产量形成期,单株的花朵数、胚珠数,取决于开花前植株的花芽多少和发育状况,而角果数、粒数、粒重和含油量,却受花期的植株生理机能及外界环境因子的影响。为了探明早熟油菜的产量形成过程,采取相应的措施,争取高产稳产,我们于1975～197T年,连续三年进行了油菜籽灌浆速度的观察。用“23号”油菜作试验材料,在即将进入盛花时,取主序中下部当天开放的花朵挂牌标记,共约
Rape is an infinitely inflorescence inflorescence, after the beginning of flowering, it will enter into the period of yield formation. The number of flowers per plant and the number of ovules depend on the flower buds and development status of the plants before flowering. The number of pods, grain number, grain weight and oil content , But by the flowering plant physiological function and external environmental factors. In order to find out the process of yield formation of precocious rape and take corresponding measures to strive for high and stable yield, we observed the rapeseed filling rate for three consecutive years from 1975 to 197T. With “No. 23” rape as test material, about to enter the full bloom, take the main order of the lower part of the day open the flower tag, a total of about
