REGENERATION OF MICRO CUTTINS WITH DIFFERENT SIZE AND ORIENTATION IN TEST TUBE

Abstract

The article is devoted to the optimization of one of the factors influencing the success of micropropagation – the choice of the optimal size of the explant and the method of its expo-sure in a test tube. Many studies have con-firmed that the size of the micro cuttings and its orientation during planting can affect the speed of growth processes and the survival rate of plants. The experiment was set on the Fio-letoviy Ranniy grape variety. The best size of the micro cuttings and the method of its orien-tation in the test tube are established.
