The yield of protoplasts with vigour was the highest under the following conditions： 1.5% cellulase Onzuka RS, 0.5% pectinase Y-23, 0.6 mol· L^-1 mannitol, pH 5.8, digestion time 2 h, and temperature 27℃. After isolation and purification, protoplasts were cultured in solid and liquid combined medium, which included KM8P, 0.6 mol· L^-1 mannitol, 1.0 mg· L^-1 2, 4-D, 0.2 mg· L^-1 NAA and 0.2 mg· L^-1 KT. The division of the protoplasts first emerged in medium after cultured 4 days, and emerged only a few times.展开更多
