| The florescence of Onc. Gower Ramsey was concentrated mainly between November and December. In order to enter the
market during the Spring Festival in Guiyang, the two years old tissue culture seedlings of Onc. Gower Ramsey were used as experiment materials which treated with different illumination, different supplementary illumination time, water control, low temperature delaying in night, different fertilization and different hormone measures. the results showed that it had significant impacts on new buds germination and growth by different illumination, different fertilization and different hormone measures, under natural temperature condition in greenhouse (5~35℃). It had significant impact on flower bud germination and pedicel growth by treating with different fertilizer measures,NPK ratio and types of hormones. In the prophase of mature seeding flower bud differentiation (5~6 months), to enhance the proportion of potash fertilizer, it can increase the flower bud germination rate compared with contrast (balanced fertilizer treatment) significantly and the
flower bud germination rate of potash fertilizer treatment is 1~2 times greater than contrast, but it had no effects on the full-blossom period of mature seeding. Spraying 20~30 mg/L GA3 in between August and September, the flower bud germination rate is 1.3 time greater than contrast, the full-blossom period of GA3 treatment concentrated in November and December, and the full-blossom period of GA3 treatment delayed 45 days compared with contrast. |
