In vitro разможаване на черешовата подложка Gisela 6.

The experiment was carried out in 2017-2018, at the laboratory for in vitro propagation in Fruit Growing Institute- Plovdiv. After decontamination, the explants are cultured on a non-hormonal nutrient medium. Pure and vital plantlets after 25-30 days are transferred in propagation media. Successfully propagated plants are rooted and subsequently adapted to outdoor conditions in two different ways. In the conducted experiments, plants grown in MS medium with 1.0 BАР mg. L- 1 the highest multiplication rate (3.67) was obtained. In rooting rate, the plants cultivated in nutrient media without GPR-s, percentage of rooting was 0%. Highest percent of rooting was achieved in liquid media containing 1.0 and 1.5 IAA mg .L-1liquid nutrient medium gave a slightly lower rooting percentage, but the other plant parameters: number of roots, length, height and number of leaves are better than the plants environment with higher concentration of auxins. The plants were acclimated by two methods: traditional and floating. There is almost no difference in the percentage of plant survival and newly formed leaves. The difference is in their height, which with better indicators are plants adapted in float system.. A low concentration of IBA 0.5 mg. L-1 in [ABSTRACT FROM AUTHOR]
