Effect of prolonged cultivation on the micropropagation in vitro of mint cultivars and breeding samples

Abstract

The influence of the genotype and the number of subcultures on the development of meristem cultures of five mint cultivars and breeding samples – Krasnodarskaya 2, Diana, K37, No. 2.8.14, A 2 ( Mentha spp.) was studied. At the second stage of micropropagation, the analysis of morphometric parameters of explants during six subcultures of four genotypes showed an increase in the multiplication index at 4-5 th passages, while in the sample A 2 - at 3-4 th passages.
