- Nowadays, the use of natural polysaccharides in the field of agriculture has increased in order to achieve sufficient yields and quality. Minimal research on effect of biopolymers on growth ornamental plants has been published. Verbena bonariensis L. is a valuable perennial species, recommended for cultivation in gardens and green areas, as well as cut and pot plant. The main objective of the investigation was to analyzed the effects of three polysaccharides on the growth and flowering of V. bonariensis. The plants were sprayed with aqueous solution of chitosan, gellan gum or kappa-carrageenan at a concentration of 0.2%, five times. Control plants were treated with water. The results indicated that polysaccharides significantly enhanced the plant height, number of inflorescences and number of leaves of V. bonariensis plants. Application of chitosan and gellan gum significantly increased the stomatal conductance by 13.8 and 16.3 % and enhanced the number of shoots per plant by 29.4 and 37.5 % compared with that control, respectively. Among the three polysaccharides, gellan gum proved best and gave significantly maximum fresh weight of aboveground part and fresh weight of root by 34.3 and 114 % over the control one.
