在影响果形的因素中,除因果实发育早期的温度,水份状况,受精程度等原因外,还有一个“花粉直感”的影响,但是果实的着生状态对果形的影响也有关系,根据1973年在统计“花粉直感”试材的果形指数时发现,所有杂交组合的果形指数均小于相邻的对照果,分析可能是与花序留果数有关。当? Among the factors affecting the fruit shape, there is also a “pollen feeling” effect in addition to the temperature, water status and fertilization degree at the early stage of fruit development, but the fruit status of the fruit is also related to the fruit shape. According to the statistics of fruit shape index of “pollen directly” in 1973, it was found that the fruit shape index of all the hybrid combinations was smaller than that of the adjacent control fruit. The analysis may be related to the number of inflorescence fruit. when?
