Evaluation of germination and survival of French bean (Phaseolus vulgaris) plants for harvesting depending on weather conditions, variety characteristics and a biological product use

The article presents the results of two field and one laboratory experiments that assess the germination and survival of plants for harvesting of various varieties and local forms of common beans. The work also identifies the dependence of these indicators on weather conditions, the genotype of varieties and the effect of plant growth regulators. Field germination of French beans depends on the variety and fluctuates from 19.3 to 90.0% on average over the three years of research. Such varieties as Saxa variety without fiber, 615 variety, Mramornaya variety, Tip-top variety, Shef-Povar variety, Barlotto zernovaya variety, Khabarovskaya variety, as well as individual local forms, has shown a consistent high field germination of at least 70%. A high survival level of plants for harvesting (from 85.4 to 100.0%) has been noted for all varieties and local forms under study. Plant growth regulators have a positive effect on laboratory and field germination and survival of French bean plants for harvesting. It has been shown that the treatment of seeds and vegetative plants with the humino-fulvate complex preparation increases these indicators by 5-7% compared to the control type.
