Abstract
Viral diseases cause significant harm to fruit crops, often making it economically unprofitable to operate plantations or causing the death of plants in the nursery and gardens. The main thing in the prevention of viral infections is the planting of industrial plantations with cured planting material. The production of improved planting material consists of several stages. Initial plants choose plants, typical for the variety, characterized by high productivity. After the selection of the original plants, they are tested for viral infection and recovery (if testing revealed diseases) and reproduction. Healing of the initial plants is carried out by the method of apical meristem culture, thermotherapy methods, chemotherapy and their combination. The article presents data on the diagnosis of juice-carrying viruses by the method of herbaceous indicators and RT-PCR, the improvement of varieties and rootstocks of plums and cherries by the method of culture of apical meristem in combination with thermotherapy. The stages of clonal micropropagation technology from sterilization of apex tissues introduced into the culture, regeneration, proliferation (reproduction) and rhizogenesis (rooting in vitro) have been worked out. The influence of monochromatic light on the processes of regeneration of plant tissue is shown in vitro. In culture in vitro introduced plants two varieties and two rootstocks of plum, two varieties and two rootstocks of cherry. For each varieties and rootstocks optimized conditions for sterilization of exploiters introduction to tissue culture. The composition of nutrients in stages introduction in vitro, micropropagation and rooting microcloned plants. Thermotherapy regimen worked out. Established by positive effect of red and blue LED lamps on the proliferation of apex varieties and rootstocks of stone crops. In culture ex vitro obtained virus-free pre-basic uterine plants of clone rootstocks WC-13 and BBA-1.
