在我们的现实生活中,有很多生物的果实是没有种子的,这些植物果实的形成没有按部就班地经过传粉、受精过程等自然过程,而是受到外界条件如经过冷、热、光等物理、化学催化或生物药剂的刺激后,由子房直接发育成果实,我们把这种现象叫做单性结实。无子番茄就是没有种子的番茄,无籽西瓜是无核的西瓜,它们都属于单性结实,但二者的形成机理大不相同。
In our real life, there are many biological fruits that are seedless. The fruits of these plants are not formed step by step through the natural processes of pollination and fertilization, but are subjected to external conditions such as physical, chemical, Catalytic or biological agents stimulate the development of fruits directly from the ovary, we call this phenomenon called uniparent. Seedless tomato is a seedless tomato, seedless watermelon is a seedless watermelon, they are all parthenocarpy, but the formation mechanism of the two very different.
