Pollination and fruit formation in tomato culture in protected ground

Бесплатный доступ

Relevance The structure of the flowers of tomatoes is very thin adapted to self-pollination, and any violations of the technology of cultivation in protected ground lead to a significant reduction in the ability of plants to pollinate and fruit set. Violation of growing conditions can lead to changes in the structure of the inflorescences and flowers, which negatively affects pollination and fruit formation, reducing the yield.The article presents a review of literature data and the author’s own research on this topic. It has been established that growing conditions in cultivation structures have a greater effect on the amount of pollen produced in tomato flowers and to a lesser extent, on its quality. In the flowers of the first inflorescence, the least amount of pollen is produced. This is due to the fact that the formation of this inflorescence occurs in the seedling period, while it is experiencing more stress. Basal (the first in the inflorescence) flowers produce low-quality pollen, while its amount is maximum...
