| Sumario: | The use of plant growth regulators is a perspective way to increase seed productivity of vegetable crops in cultivation technologies.
The purpose of the work was to scientifically explain the use of pre-sowing seed treatment with plant growth regulators of different
directions, as an element of technology for growing radish plant of Zorya variety, as well as to identify their influence on seed productivity
and seed quality.
The research was carried out on seeds of radish sown of Zorya variety. Pre-sowing soaking of seeds was made with aqueous solutions of
retardants ethephon (0,25 %) and chlormequatchloride (0,25 %), as well as stimulants reastim (1 g/l) and succinic acid (1 g/l). Control
samples were treated with tap water. The germination energy and general seed germination were determined in the process of research.
It was found that the using of plant growth inhibitors with anti-gibberellin mechanism of action and ethyleneproducer esfon (0,25 %) as
well as chlormequatchloride (0,25 %) (quaternary ammonium compound) increased the seed germination of radish of Zorya variety. The
best effect was found with the use of chlormequatchloride (0,25 %). Retardants increased the germination energy of seed.
It was researched that the use of plant growth stimulators with different mechanisms of action (succinic acid and reastim) increased the
intensity of germination and germination energy of radish seeds in comparison with the control variant. The best effect was found with
the using reastim (1 g/l).
The question of identifying the influence of modern plant growth regulators with a different mechanism of action on the seed productivity
of vegetable crops remains relevant and actual |
