| Notes | 45-1381/S Objective】The present experiment was conducted to investigate seed germination and rapid propagation technologies of Camellia nitidissima from Fangchenggang,Guangxi, and establish its tissue culture system, in order to provide a basis for tissue culture and rapid propagation of C. nitidissima. 【Method 】The tissue culture experiment was conducted with C. nitidissima seeds at 3 development degrees as explants and 17 kinds of culture media with different hormone concentrations. Then the effects of these treatments on seed germination rate, multiplication coefficient, plant height and leaf number were investigated, so as to screen optimal medium for multiplication and strengthening seedling culture.【Result】The results showed that, the selected seeds with endosperm diameter of greater than 1.0 cm were inoculated into culture medium of MS＋GA31.0 mg/L, and the germination rate was up to 82.4%. The multiplication coefficient first rose and then declined with increase of 6-BA concentration, when 6-BA was at 3 |
