The aim this research was check the viability end to determine a suitable substrate for rooting by microcutting technique and blueberry plant growth cultivar Georgiagem. The microcuttings were kept under moist micro-environment conditions at both regulated temperature and light. The microcuttings were kept in to boxes of ethylene polvtereftalate, during 48 days. The substrates Sphagnum sp. peat moss and the mixes of peat + perlite, peat + perlite + coconut fiber and peat + perlite + sawdust allowed higher rooting percentage.
