凉蔗2号宿根能力研究

The Study of Ratooning Ability of Liangzhe-2

8年18点(次)宿根蔗试验结果表明,凉蔗2号宿根发苗数、分蘖率、经济性状、工艺性状各指标值显著优于对照川蔗13号,初级试验4年8点(次)宿根蔗试验结果,同期宿根发苗时间、同期分蘖时间、宿根蔗拔节期皆早于对照。在整个选育过程中,凉蔗2号表现出了独特的宿根能力:宿根发苗早,发苗多,封行早,分蘖极强,拔节早,宿根性极强。凉蔗2号前期生长快,中期生长平稳,末期生长后劲足,总体生长势中等,其多年种植高产高糖,宿根效益显著,是一个实现工农双赢不可多得的优良蔗种。

18 ratooning tests in 8 years were conducted and the result showed that the number of germination, tillering rate, economic features and technical character of Liangzhe-2 were much better than those of the check Chuanzhe-13. The germination and tillering and elongating stage of Liangzhe-2 started earlier than that of Chuanzhe-13 in the same testing period. During the whole process of breeding, Liangzhe-2 showed very distinctive and strong ratooning ability, with early and better germinations, early elongation and row-sealing, and better tillering. It grows fast in the earlier stage, smoothly in the medium stage and vigorously in the later stage. Liangzhe-2 is an elite variety that can bring benefit both for the farmers and sugar processing enterprises because of its high yielding, high sucrose ability and high benefit.
