Abstract:

 The regulator of anti-stress action Epin-Extra (24-epibrassinolide) was tested in laboratory and field (protected ground) conditions. The aim of this research was to study the influence of growth regulators on the growth, development and productivity of improved initial promising varieties of potato: Native (cultivated varieties Udacha) and foreign (cultivated varieties Red Scarlett) selections obtained by the method of apical meristem in the Volga-Vyatka region. The obtained results suggest a promising use of the product for improving the growth and development of plants in vitro. Adding Epin-Extra into an artificial culture medium at the final stage of micropropagation in vitro increases the height of plants by 29.6-47.7%, the number of internodes in plants by 26.4-25.7% depending on the cultivated variety, increases the root growth for cultivar Udacha 2.1 times and reduces the one for the cultivar Red Scarlett 1.9 times. The use of the Epin-Extra product-in recommended concentration for growing mini-tubers by seedling method in protected soil (greenhouse) in the budding phase-increases the biometric indicators such as plant height (35.7-21.8%), number of stems in the bush (30.9-19.0%) and mass of roots (19.1-8.5%), depending on the variety. As a result, the treatment with Epin-Extra increases productivity by 25.6-15.9%, the multiplication factor by 25.3-18.4%, as well as helps to reduce the prevalence (by 69.5-44.1%) and development (by 50.0-44.3%) of the late blight on the tops of potato plants, depending on the cultivar.
