THE PROSPECT OF ACTINIDIA MICROPRODUCTION. INITIATION STAGE

The fruits of the Actinidia genus contain a large amount of biologically active substances with antioxidant properties and serve as a valuable source of vitamins, catechins, pectins and many other compounds. The basic collection of actinidia available in the berry crop department of the Institute for Fruit Growing is currently represented by three winter-hardy species (A. kolomikta, A. arguta and A. polygama). In order to meet consumer demand for new species and varieties in a timely manner, it is necessary to widely introduce new technologies for the production of planting material along with traditional methods of reproduction. Micropropagation and plant health improvement is the most advanced and widely used methodology of applied biotechnology in different countries. The article analyses in detail all the nuances of the in vitro culture initiation stage of actinidia, including the timing of explant isolation, explant types, sterilization schemes, nutrient growth media of the initiation stage, and other factors.
