Abstrakt
Agricultural cultivation of astragalus is fraught with a number of difficulties caused by
both certain requirements for climatic conditions and individual characteristics of plants of this
genus. In this study, carboxyalkylated derivative of chitosan was first proposed to use for
improvement of astragalus propagation. Effects of N-(2-carboxyethyl)chitosan on in vitro
A. glycyphyllos and A. membranaceus seed germination and seedling growth and development in
comparing with β-alanine and chitosan acetate were detected. Carboxyethylation of chitosan
leads to an increase in hydrophilic properties of the molecule, which enhances a penetration of
nutrients inside the plant owing to improved solvating effect and bioadhesive activity. Seed
germination assay were performed on Murashige-Skoog growth medium with or without tested
compounds. N-2-Carboxyethylated derivative of chitosan was found to demonstrate active
stimulating effect on the plant growth and development, contrary to the effect of acetate chitosan,
but not to cause an activating effect on seed germination, while β-alanine does.
