Application of growth regulators-antistressors in complex with universal bioactive fertilizers in seed production of gourds

Relevance. The effectiveness of seed soaking before sowing in a solution of preparations of the epibrassinolide group for the protection and preservation of seedlings of gourds from temperature stresses, increasing the yield of fruits and seeds was studied.

Methodology. The objects of research were preparations Epin Extra, Epin Plus, EcoFus, Ferovit, Zircon and Siliplant, which allow to overcome the effects of temperature stresses, increase immunity, and have a stimulating effect on seed germination and plant growth of vegetable crops.

Results. In the course of the studies, it was found that preparations of the epibrassinolide group contribute to a significant preservation of seedlings of gourds with prolonged exposure to low temperatures. Soaking watermelon seeds of the Tersky early variety before sowing in a solution of drugs from the epibrassinolide group ensured the safety of seedlings from 24.2 to 35.3%, while in the control variant, the death of plants was 100%. Epin Extra had the greatest anti-stress effect on watermelon. Preparations on melon showed less efficiency in protecting seedlings, 21.1-27.3% of plants survived. The maximum number of seedlings remained when using Epin Plus. It should be noted that soaking seeds in solutions of preparations of the epibrassinolide group, to protect seedlings of gourds from damage by low temperatures, is an effective technological operation that makes it possible to smooth out the impact of the stress factor.
