Determination most of adapted varieties of cultivated plants on the base of the assessment of biology and dynamics of development of epiphyte and endophyte microbiota

Abstract

The article presents long-term (2003-2016) data on the study of the adapted potential of small fruit plant varieties based on the parameters of endophytic and epiphytic microbiota. The general condition of plants was assessed. Various varieties of red currant, black currant, gooseberry, strawberry were tested for the presence of endophytic microbiota. Samples of washouts from the surface of leaves of healthy plants were taken. It was found that both endophytic and epiphytic microbiota include bacteria belonging to the genus Pseudomonas, fungi (from the genera Alternaria, Fusarium, Penicillium). It was found that the parameters of endophytic microbiota clearly refl ect the state of plants. Longterm studies have shown that the endophytic microbiota is an parameter of the state of the plant organism and is an important criteria for assessing the adaptive ability of plants. In plants with a high level of adaptation, there is an increase in the frequency of testing for a bacterium that suppresses the growth of dangerous fungal pathogens in pure form and as part of a mixed infection, as well as a low percentage of negative tests. Varieties of red currant, black currant, gooseberry, strawberry with a high level of adaptation are identified. These varieties are of practical interest, both for the breeding process and for production.
