| 摘 要： | 为了解13个桂糖新品种(系)蔗糖分、理论产糖量变化规律和成熟期情况,对13个桂糖新品种(系)进行为期6个月的13次糖分分析,分析其蔗糖分、理论产糖量变化规律和成熟期情况.结果表明:属特早熟高糖的品种(系)为桂糖02/901,属早熟高糖的品种(系)有桂糖02/761、桂糖02/208、桂糖02/770、桂糖01/122、桂糖02/351、桂糖02/1247和桂糖02/360;属于中熟的品种(系)有桂糖02/133和挂糖99/107；属于晚熟的品种(系)有桂糖99/181、桂糖99/156和桂糖02/833；理论产糖量潜力较高与ROC22相当的品种(系)为桂糖02/901、桂糖01/122和桂糖02/208.结论:不管是早熟材料还是中、晚熟材料,其蔗糖分峰值出现的时间大致相同,而重力纯度的峰值出现则比蔗糖分晚一个半月以上.理论产糖量的峰值出现时间与蔗糖分基本一致,但其后有一个平台期,并可持续到3月底.

| Abstract: | In order to study the sucrose content,maturity and theoretical recoverable sugar(TRS) of new varieties,13 sane quality analyses for 13 new GT sugarcane varieties were done during sugar accumulation and ripening stage from October to April.The result showed that the sugarcane cultivar GT02/901 was very early-maturing variety with high sucrose content.GT02/761,GT02/208,GT02/770,GT01/122,GT02/351,GT02/1247 and GT02/360 were early-maturing varieties with high sucrose content.GT02/133 and GT99/107 were intermedi... |
