All plants in nature have their differences. According to the separation of sexes, all types of flora are divided into such groups:
Dioecious plants are those who have female flowers on some individuals, and on others male. Their pollination occurs in a crossroads. So the fruits of dioecious trees are tied if pollen of individuals from men’s flowers is transferred to trees with female flowers. This process would be impossible without bees, on which further pollination depends. The disadvantage of such a device as dioecution is that the seeds do not appear in 50% of plants of a certain species. In the nature of such species there are no more than 6%. These include the following plants:
Differences of male and female individuals
It is always difficult to distinguish between male and female individuals of dioecious species, those who are engaged in the cultivation of flowers, trees and other crops should learn to determine the floor. The flowers of male individuals have dotted pollen stamens, and their stigma is poorly developed. Female flowers almost always lack stamens.
If in the garden some tree does not give fruits, then most likely it belongs to dioecious types. To correct the situation, you need to plant a plant of the same species nearby, and then thanks to the bees that help the flowers to pollinate, the tree will begin to be fruit.
Male flowers of dioecious plants usually give a lot of pollen. This is due to the fact that female individuals do not always grow nearby, which means that pollen should be enough for pollination of fargrowing female plants. It is light and can rush of wind spread to longdistance territories.
How is the pollination of dioecious individuals
Figs are a dioecious plant, and on its example we will consider how its pollination occurs. He has small and not very remarkable flowers. Pollination is due to Osam-blastophages. The female of this species is looking for men’s flowers on which male individuals are sitting. Thus, the wasp collects pollen from men’s flowers and further pollinates the female flowers of figs. So fertilization occurs in the OS, and thanks to them, fig flowers are pollinated.
Dioecution is a special adaptation of plants, which is manifested that one species has female and male individuals, but quite often it is difficult to determine their gender. In such cases, breeders try to withdraw new oneday species so that in the future the gardeners do not have a problem with the fruiting of cultures.
