Transplanting Season of 17 Species of Primulina

To provide technical support for the industrialized and large-scale production of tissue culture seedlings in the future, the effects of different seasons in southern Guangxi on the survival of transplanting of tissue culture seedlings of Primulina were discussed. In this paper, the effects of seasons on the survival of transplanting were studied using the group cultured seedlings of 17 species of Primulina. The survival differences of different species in the same season and the survival differences of the same species in four different seasons were analyzed. The results showed that most of species had higher survival rate when transplanted in spring, and the highest and lowest was P. tribracteata and P. crassirhizoma, respectively, with the survival rate of 100.0% and 51.3%. The suitable species for transplanting in spring were P. guigangensis, P. sclerophylla, P. yungfuensis, P. purpurea, P. tribracteata, P. glandulosa, P. glandaceistriata, P. liujiangensis, P. pungentisepala, P. macrorhiza. 17 species had lower survival rate in summer. The species with the highest and lowest survival rate was P. macrorhiza (68.7%) and P. lijiangensis (15.3%). Among the 17 species, more than half of them had higher survival rate when transplanted in autumn and winter. The highest survival rate of transplanting in autumn was for P. guihaiensis and P. napoensis, and the lowest survival rate was for P. glandaceistriata. Autumn was the best transplanting season for P. guihaiensis, P. crassirhizoma, P. Napoensis. In winter, the survival rate of P. hiemalis was the highest, and that of P. yungfuensis was the lowest. Winter was the best transplanting season for P. guizhongensis, P. atropurpurea, P. hiemalis, P. lijiangensis. The transplanting season of 17 species was the best in spring and the worst in summer. Different species have different suitable transplanting seasons, so it is necessary to transplant the appropriate species according to the seasons to ensure a higher survival rate.
