Abstract
The effect of pea and soybean lectins on the symbiotic properties of nodule bacteria Rhizobium leguminosarum bv. viciae 240б and Bradyrhizobium japonicum 634б during the formation and functioning of symbiosis with pea (Pisum sativum L.) and soybean (Glycine max L. Merr.) plants respectively was investigated. It was shown that incubation of homologous rhizobia with plant-host lectin had increased bacteria nodulation ability at seeds inoculation, nitrogen fixing activity of root nodules and symbiosis efficiency that had resulted in intensification of plants’ photosynthesis, positive changes of legumenous plants growth, formation of vegetative mass and harvest. The use of complex of complex compositions based on the legume lectins and homologous rhizobia for pre-sowing seeds treatment was shown to be perspective in order to increase seed productivity of legumenous plants.

Лектини бобових рослин є біологічно активними речовинами [1, 22], які здатні прямо або опосередковано впливати на ростові процеси рослин і їхню продуктивність [18, 19]
Інтенсивність фотосинтезу визначали за допомогою оптико-акустичного інфрачервоного газоаналізатора за методикою Гуляєва зі співавторами [8], за що висловлюємо вдячність співробітникам відділу екології фотосинтезу Інституту фізіології рослин і генетики НАН України (ІФРГ НАНУ)
