| Popis: | Introduction: Chitosan is one of the polysaccharides containing nitrogen which is synthesized naturally by deacetylation reaction of chitin and is confirmed as one of the efficient biostimulants for improvement of secondary metabolites production in medicinal plants. Objective: To evaluate the effect of different concentrations of chitosan biostimulant on vegetative biomass traits and secondary metabolites of Stevia plant. Methods: The experiment was conducted in a randomized complete block design with three replications in greenhouse conditions. The treatments were spraying of chitosan in four levels (0.05, 0.1 and 0.2 percent) and control treatment (spraying with distilled water). Results: In this study, the obtained results of variance analysis showed that spraying of chitosan had significant effect on leaf dry weight, shoot dry weight, leaf length (P |
