The paper is devoted to the optimization of one of the factors influencing the success of micropropagation – the choice of the optimal part of vine to take explant, size of the explant and the method of its exposure in a test tube. The studies have confirmed that the place, where micro-cutting was taken, its size and its orientation during planting can affect the speed of growth processes and the survival rate of plants. The experiment was put on the Purple Early grapevine variety. The part of vine for taking micro-cutting, best size of explant and the method of its orientation in the test tube are established.
