Techniques of Florescence lnducting and Hybrid Seed Raising of some Shy- Flowering Sugarcane Varieties in Subtropical Region

The present paper dealt with the florescence inducting and the hybrid seed raising of some shy- flowering sugarcane varieties i.e. Tongan Chewing Cane, Maan Chewing Cane,Mintang 7O-611 and Minxuan 703.The artificial environment of Photoperiodic treatment with blue and far-red lights was set up from December to next January in Zhangzhou. The techniques listed follow were used go induct the florescence,(1)to breed the seedlings to overwinter in greenhouse in the Autumn,(2)to begin inducting the florescence early spring next year,(3)to use the pho-toperiodic treatment of blue and far-red light,(4) to keep high humidity in the greenhouse. The results showed that the varieties had been to flower and bring some hybrid seeds under the treat-ment with the techniques.
