THE EFFECT OF GROWTH REGULATORS ON THE GERMINATION OF SEEDS, THE GROWTH AND DEVELOPMENT OF TRIBULUS TERRESTRIS L

Abstract

                    Puncture vine (Tribulus terrestris L.) belonging to the Zygophyllaceae is an important medicinal plant. However, the number of this plant in the nature has decreased dramatically because of narrow distribution, overexploitation and low germination of seeds. In this paper, the authors introduce some research of the effect of plant growth regulators (Root king No.1 and Super roots bimix) on the germination of seeds, the growth and development of Tribulus. terrestris

L. The results have shown that Super roots bimix has had better effeet than Root king No.1. Using Super roots bimix at the concentration of 100 ppm has helped to shorten the germination time with 80% germinated seeds in 25.5 hours and increase the growth ability of the seeds to 94.1%. In addition, using Super roots bimix at the concentration of 100 ppm has also had a positive impact on the growth and development of seedlings.
