Abstract

The analysis of plants with abnormal type of growth from the collection of succulent plants of Academician O.V. Fomin Botanical Garden of Taras Shevchenko Kyiv National University are made. It was found 22 species of fasciated plants, belong to 14 genus and 3 families. Most species belong to the Cactaceae family. We tested the hypothesis fasciation occurrence as a result of defeat viruses, microscopic fungi, the hypothesis of the mechanical damages to plants. We can assume that viruses, microscopic fungi, mechanical damage to plants do not cause abnormal growth forms on Cactaceae family.
