Abstrakt
An article provides information about buds organogenesis in plants of columnar apple
cultivars in the Forest-Steppe of Ukraine (Kyiv), which allows to establish the features of this
process in complex fruit formations of different ages, and their productivity and longevity. We
recommend studying of apple trees productivity in the process of its formation by analyzing of
rudimentary organs formation and their consistent development into vegetative and generative
organs, which are elements of productivity. Studies of organogenesis different-age fruit
formations of columnar apple cultivars were conducted in the northern part of the Forest-Steppe
of Ukraine during 2016–2020. It was established that separate age sections of columnar apple
trees trunk formed different initial productivity potential. In plants of all studied varieties and age
groups, the laying of generative buds, the implementation of reproductive elements in V–IX and
X–XI stages of organogenesis were more effective in older age areas of the trunk. Complex fruit
formations, regardless of the trunk age where they are placed, form a high potential for
productivity, which is effectively realized. The dependence of the formation and productivity
potential realization on the stages of organogenesis and meteorological factors is established.
