纬度和品种是影响甘蔗开花中比较重要的因素，拔地拉、黑车里本、闽糖７０－６１１、粤糖５７－４２３等难开花的重要亲本人工诱导开花的研究，已列入国家“九五”科技攻关内容。本研究采用固定日长加蓝光与远红光作辅助光照；处署盆栽，次年清明开始诱导；小阳秋杂交温室加遮阳网和午间喷雾等措施，使上述亲本在亚热带的福建省漳州（北纬２４°３０′、东经１１７°３９′）诱导孕穗开花成功，其中拔地拉和黑车里本是首次诱导开花。本研究还利用上述亲本配制了１５个杂交组合。
Latitude and variety are the more important factors that affect the flowering of sugarcane. Artificial flowering of important inflorescences such as pullra, black cabbage, fujian 70-611, and yugu 57-423 are all included in the national “nine Five ”scientific and technological content. In this study, fixed day long plus blue light and far red light were used as assistant lighting; potted plants were planted and the next year Qingming began to induce; Xiaoyang autumn hybrid greenhouse plus shading net and midday spray were adopted to make the above-mentioned parents in the subtropical Zhangzhou North latitude 24 ° 30 ', east longitude 117 ° 39') to induce booting flowering success, which is the first pull-out and black car flowering. In this study, 15 hybrid combinations were also made using the above-mentioned parents.
