The effect of cultivation conditions on the growing processes of grape plants in vitro

Abstract

One of alternative ways to maintain valuable genetic material is to develop optimal conditions for cultivation in an in vitro system. The goal was to evaluate the condition of plants based on changes in the shoot length indicator in order to explore the maintaining mode of the collection. We took the experimental samples from the “Vegetating collection of plants in vitro of promising varieties and clones of grapes”: 13 local Crimean varieties and 9 varieties of the Institute Magarach selection. Plant containing culture bottles were in the cold storage without internal lighting at 10-12°C for 6 months. The cultivation findings demonstrated that grape varieties differed in viability and intensity of morphogenesis. Moreover, after storage, they had a high regenerating ability of the buds.
