摘　　要：海南甘蔗育种场目前常用的杂交亲本的花期自11月上旬开始，持续3个月左右。一般品系的花期可持续2个星期左右，部分品系可达1个月，甚至更长。8月中旬到10月中旬的强台风袭击可能导致部分常年早花易花的品系不能开花。通什具有比崖城更优越的甘蔗开花条件，多数在崖城难花不花的品系在通什能开花，且花期较长。The flowering season of currently used sugarcane parents at Hainan Sugarcane Breeding Station begins in early November and lasts about 3 months.Flowering seasons for individual clones are mostly over 2 weeks, some extend a month or even longer. same easy-flowering clones may fail to flower due to the damage from violent typhoon between mid-August and mid-October. Most of those shy- or non-flowering clones at Yacheng Station can normally flower. or have longer individual flowering seasons at Tongza sub-station where the natural condi t ions for f floral induction are more favorable.
