Kiwifruit not bearing fruit? You may have planted a male vine, and grafting can solve it

Some kiwifruit vines never bear fruit. There is no need to wonder why; the reason is simple, because kiwifruit comes in male and female! Just like people, asking a man to give birth is making things hard for him, isn't it? Making a man give birth is currently quite difficult with existing technology; everyone knows that although Jin Xing underwent gender reassignment surgery and became a woman, she still cannot bear children because she has no uterus.

But making a male kiwifruit bear fruit is much simpler than with people, and it is very easy to achieve: grafting! In a previous article by Science Xingnong, an explanation was given about ginkgo being male and female. In terms of physiological structure, kiwifruit is also like ginkgo, with male and female structures: that is, botanically speaking, dioecious.

Everyone is probably fairly clear that, like the rapeseed, soybean, rice, wheat and so on that we see, after flowering, careful observation shows that they are hermaphroditic flowers, while for the pumpkins, cucumbers, watermelons and so on that we see, after flowering the male and female flowers are separate, and this situation belongs to sex differentiation, and the common point of the above two situations is that both male and female are on the same plant.

But the kiwifruit mentioned here is different, because its male and female flowers are not on the same plant. This is also called dioecious.

Next, let us introduce the idea of how to make male kiwifruit plants bear fruit. As already introduced above, it is through grafting, and grafting techniques have also been covered in previous articles, that is, transplanting the branches or vegetative organs of other varieties or species onto a rootstock so that they survive through the nutrients provided by the rootstock plant, such as grafting watermelon onto pumpkin, grafting cucumber onto pumpkin in production, and grafting Christmas cactus onto cactus in horticulture, and so on.

After grafting, the scion only receives the nutrients provided by the rootstock and will not undergo DNA genetic mutation because of this, so after grafting, the growth habits of the scion will not change.

The idea mentioned here of grafting female kiwifruit onto male kiwifruit to make male kiwifruit bear fruit is not complicated in terms of grafting technique and is still very easy to achieve. In addition, because kiwifruit is a dioecious vine fruit tree, and farmers plant fruit trees to obtain economic benefits, when planting, female plants are used as the main planting, with male plants arranged at a ratio of 1:5-8 as a pollination source to ensure yield.
