PROTECTIVE-STIMULATING PROPERTIES OF CHITOSAN IN THE VEGETATION AND STORING TOMATOES
Journal Title: Progress on Chemistry and Application of Chitin and its Derivatives - Year 2017, Vol 0, Issue
Abstract
Data for using natural chitosan for plant-induced resistance to diseases and physiological stresses are presented. Provision on the possibility of combining resistance inducer properties not only to diseases, but also to physiological stresses, is postulated. It is shown that treatment of tomatoes and tomato seeds with chitosan leads to both increased resistance and increased reproductive abilities of tomato plants. The biogenic elicitor chitosan, based on a "Agrohit" ("АгроХит") preparation, induces the resistance of tomatoes to Phytophtora infestan and Alternaria solani. The plants grown from seeds processed by chitosan exhibit less damage from pathogens during the vegetation period. The action of the elicitor influenced a change in terpenoid biogenesis (formation of a phytoalexinari chitin). Beside protection functions, this preparation has stimulating activity and can be used to achieve higher yields of tomatoes, which are tolerant to stress conditions. The use of elicitors for plant-induced resistance provides ecological safety and an economically significant improvement of the parameters of plant produce and storage.
