Peculiarities of substrate selection for in vivo adaptation of plants-regenerates of rose essential oil

Abstract

In research we studied substrates selection for successful adaptation of rose essential oil (variety Lan’) after microclonal propagation. The results showed that the most advisable is to use a mixture of peat and perlite in a ratio of 2:1. The survival rate of plants on the peat mixture with river sand was 70 % after 14 days of adaptation period. In the corresponding period this index was 62 % on a coconut substrate without impurities and 60 % on a coconut substrate with perlite. Using of a single-component substrate for the adaptation of rose essential oil are inadvisable, because the adaptation efficiency doesn’t exceed 50 %.
