The use of epibrassinolide in the cultivation of potatoes |
|
Studied the effectiveness of the use of the drug epin-extra (24 - epibrassinolide) for growing potato varieties Zhukovsky. Established a positive effect of growth regulator on the productivity of potato plants. When using the drug as a preplant treatment of micro tubers of potatoes at a concentration of 1 ml / 250 ml, followed by spraying the plants in the budding phase - the beginning of flowering (concentration of 1 ml / 5 l of water) led to an increase in the number of stems and plant height. The use of a solution of epibrassinolide during the growing season on potato varieties Zhukovsky stimulated tuberization, increased the multiplication factor by 30-80%. Due to the increase in the aboveground and underground plant biomass, the use of the drug epin-extra increased the yield of potato varieties Zhukovsky by 5–9 t / ha compared to the control.
