座果的机理前述座果过程的三个阶段中,对大多数有籽果实来说,最重要的是授粉受精过程,花粉和胚囊的健壮发育是授粉受精的准备,而胚和胚乳的发育是受精后的必然发展。观察开花前后子房的发育可见开花前子房迅速生长,到开花时中止了生长,授粉受精后就又迅速生长起来,未授粉受精的子房则停止生长而脱落。这是因为在开花前子房内含有刺激生长和抑制生长的物质。这两类物质的平衡状态及子房对这种平衡状态的敏感性,决定了子房的生长或停止。授粉受精后由于刺激生长的激素增多,抑制物 The mechanism of the fruit in the three stages of the above fruit process, the most important for most of the fruit is the process of pollination and fertilization, the robust development of pollen and embryo sac preparation for pollination and fertilization, and embryo and endosperm development After fertilization is the inevitable development. Before and after the observation of the development of ovary before flowering can be seen before the rapid growth of ovary before flowering, to stop the flowering at the time of growth, after pollination fertilization and rapid growth, non-pollination fertilization of the ovaries stop growing and fall off. This is because the ovary contains material that stimulates growth and inhibits growth before flowering. The balance of these two types of material and the ovary’s sensitivity to this state of balance determine the growth or cessation of the ovary. Pollen fertilization due to increased hormone stimulation, inhibition
