INFLUENCE OF GROWTH REGULATORS IN VARIOUS METHODS OF GERMINATION OF CANNA HYBRID RHIZOMES

Abstract

The article presents the results of a study on the effectiveness of using growth regulators Heteroauxin and Radifarm in the germination of hybrid canna on the basis of the Pryluky Research Station of the IS NAAS. The relevance of the work was the need to find alternative methods of processing planting material when growing this crop. Therefore, the purpose of the research was to study the effectiveness of using growth regulators in different schemes of germination of hybrid canna rhizomes on productive and decorative indicators. When conducting observations, analyzes and accounting of the impact, their positive effect was noted in different methods of germination: container, box and open ground, which contributed to the additional use of their inherent productivity potential. The drugs used in the experiment generally contributed to an increase in the average height, number of flowers, vegetative and generative shoots, which in turn affected the reproduction coefficient indicators. The studies found that the difference between the treated variants and the control was: in the Yellow King Humbert variety from 21.3 to 34.1 flowers, generative shoots 0.7–1.4 pcs. and vegetative shoots 0.6–1.2 pcs., vegetative propagation coefficient 0.8–1.4; in the Kron variety, the number of flowers per plant was 26.0–41.1 pcs., vegetative shoots 1.4–2.2 pcs. and generative shoots – 0.1– 0.4 pcs., vegetative propagation coefficient 0.6–1.7. Analyzing the data between growth stimulants, it can be noted that the drug Radipharm had the most positive effect on the plants.
