Abstract:
In vitro grown pomegranate seedlings were found to have a low specific leaf mass (g/dm2) in the
first day (1 day), which was supposed to be associated with high water content in the leaf during
the initial period of adaptation to natural soil conditions. As an object of the study “Qora qayim”,
“Qizil anor”, “Oq dona (Tuyatish)”, and “Achchiq dona” local varieties of pomegranate were
selected which grow in Sirdarya region of the Republic of Uzbekistan. It was also found that the
transpiration intensity was relatively high in the early stages of the adaptation period when
transplanting a plant grown under in vitro condition into a non-sterile soil environment, as well
as a decrease in water content in the leaves, i.e. a high water deficit value was observed, and
accordingly, it is recommended to increase the humidity level in the atmospheric environment
around the plant to 90-95% and then gradually reduce it to 50% in order to ensure optimal
adaptation mechanisms of the plant to soil conditions.
