Determination of transplant survival rate
Following growth enhancement, the plantlets were transplanted into a culture room for domestication. The transplanting substrate was mixture of pine forest soil, perlite, and vermiculite at a ratio of 2:1:1. Each SRP was transferred into a dedicated flask. Each group was treated with 10 plants and repeated three times. The plantlets were cultured in culture room under cool white fluorescent light (16/8h) at 23℃, and watering once a week. The survival rate of the plantlets was calculated after six months.
