Abstract

The results of the study features of one-year sweet cherry trees formation on Cerasus mahaleb and VSL-2 rootstocks are given. Varietal rootstock combinations have been identified, which ensure the production of high-quality crowned one-year seedlings, suitable for creating modern industrial plantations. The research was conducted during 2018–2021 in the fruit nursery of the educational laboratory (EL) «Fruit and vegetable garden» of the Prof. V. L. Symyrenko Department of Horticulture NULES of Ukraine. As a result of the conducted research, it was established that the seed rootstock of the Cerasus mahaleb and clone VSL-2 have a high level of survival in the first field of the seedling nursery. It was found that in the studied varieties the rootstock VSL-2 provides a higher level of grafting and overwintering of inoculated eyes compared to the Cerasus mahaleb. Seedlings on VSL-2 rootstock have a larger number of side branches than Cerasus mahaleb. The variety Talisman’ is characterized by a high ability to branch in the nursery regardless of the rootstock. Seedlings, grafted on VSL-2, are distinguished by the total length and number of main roots. No visual and anatomical signs of incompatibility of components were found in the investigated variety-rootstock combinations at the stage of growing seedlings.
