GROWTH STIMULATORS IN THE PRODUCTION OF CUCUMBER SEEDLING OF THE GREENHOUSE COMBINE
The presented material considers the possibility of increasing seed germination and improving growth processes in cucumber plants in the production of seedlings. To solve this goal, cucumber seeds were soaked before sowing in the seedling department in the conditions of winter-spring and summer-autumn turns. As an object of research, we used preparations of different chemical composition used as simulators of root formation and growth processes. It was found that the studied preparations significantly increased seed germination and germination energy, however, the best results were obtained from the action of the Quick-Link and Sprintalga preparations. Root stimulants increase the length of the root and its total weight. The root system during the seedling period grows more intensively than the aboveground organs. The most developed root system with many lateral roots and the maximum length of the head root is provided by the Quick-Link and Sprintalga root-forming preparations. Under their influence, the length of the root in the Athlete hybrid increases by 18.9 - 22.5%, and its mass by 47.1 - 52.9%, in the Mamluk hybrid, respectively, by 18.8 - 24.7% and 43.8%.
