Title: Plant regeneration from in vitro leaves of mature black cherry (Prunus serotina)

Author: Liu, Xiaomei; Pijut, Paula M.;

Publication Series: Scientific Journal (JRNL)

Description: A regeneration system was developed for Prunus serotina from a juvenile (F) and two mature genotypes (#3 and #4). Adventitious shoots regenerated from leaves of in vitro cultures on woody plant medium with thidiazuron (TDZ) and naphthaleneacetic acid (NAA). The best regeneration for genotype F (91.4%) was observed on medium with 9.08 µM TDZ and 1.07 µM NAA. The highest mean number of shoots (8.2) was obtained on medium containing 9.08 µM TDZ and 0.54 µM NAA. Genotype #3 had the highest regeneration (41.7%) with a mean number of shoots (4.8) on 9.08 µM TDZ and 1.07 µM NAA, whereas genotype #4 had a 38.8% regeneration with a mean of 3.3 shoots. Genotype #4 had the highest mean number of shoots (4.8) on 4.54 µM TDZ and 1.07 µM NAA. Silver thiosulphate at 60 or 80 µM increased the percent regeneration of the mature genotypes #3 (75%) and #4 (58%). Adventious shoots were rooted (70-76%) and rooted plantlets survived after acclimatization to the greenhouse. The effect of kanamycin concentration on adventitious shoot regeneration was also evaluated.

Keywords: adventitious shoots, organogenesis, rooting, silver thiosulphate
