ABSTRACT Synthesized growth regulators may cause a negative impact on the environment so the use of natural bio-stimulators in horticulture is becoming more popular. Some biopolymers can have a stimulating influence on the growth and development of plants. In addition, polymers can be used to form hydrogel coatings on the surface of plant organs to protect them against the adverse influence of external factors.

Coating of twin-scale cuttings in gellan gum had a positive impact on the number and weight of the bulblets.
