| Abstract | Solving of the regular fructification problem in the way of creating self-fruitful varieties, gives an opportunities to achieve sweet cherry fruits, fruit set of which low or in some case independent of pollination. To settle the self-fruitful of studying sweet cherry varieties used individual isolation made of agrofibre. Also it was made research of Gibberellins influence (50mg/l) on capability to fruit set in self-fruitless and partially self-fruitful varieties. As the result of research duke Ivanivna shown high capability to fruit set via the apomixis – 60,42 %. It is 10 % higher than via free pollination. About 26,28-37,5 % of apomictic fruit set could be achieved by using Gibberellin. As an addition it increases content of P-active substance and anthocyanins in fruits, what increases their therapeutic and prophylactic features. It gives an opportunities to create one-variety sweet cherry planting depending whether it self-fruitful or self-fruitless, and weather it fits to the growing land or not. | ||
