What are parthenocarpic varieties
Now more and more bags with seeds of zucchini and other crops appear in agricultural shops, on which the inscription "parthenocarpic" is written. What does this mean? Until now, many gardeners do not know the meaning of this word or misunderstand it.
Often in brackets next to this incomprehensible inscription they write a self-pollinated variety. But it should be said that parthenocarpic and self-pollinated varieties are not the same thing. Parthenocarpic squash is a crop that produces fruit without pollination. In this case, the zucchini themselves will not have seeds inside.
Self-pollination is a completely different process, in which pistils and stamens from the same flower are capable of pollination without the participation of insects. These zucchini grow with seeds.
Some growers write instead of "self-pollinated variety" next to the word parthenocarpic - "not requiring pollination." This formulation would be more correct. Parthenocarpic zucchini are needed in order to grow them where there are no insects or there are not enough of them for pollination. This often happens in greenhouses, but zucchini is mainly grown outdoors, so parthenocarpic varieties can be used in order not to wait long for ovaries to appear.
