摘要
对12个早、中花甘蔗亲本品种(系)进行剪叶处理,调查剪叶处理对甘蔗开花情况的影响。结果表明:剪叶处理对甘蔗开花的影响效应因品种不同而各异,可能使花期推迟或提早;影响程度也因品种不同而各异;绝大多数甘蔗品种(系)经过剪叶处理后,其抽穗率都不同程度降低。
In this experiment,12 early and moderate flowering sugarcane varieties＇leaf were cutted,and condition of sugarcane flowering were studied.The results showed that,the effect on flowering of sugarcane were discrepant for different veraties,the flowering time maybe advanced or deferred.The influence degree on flowering time was discrepant for different veraties.After leaf cutting,most sugarcane varieties＇earing rate decreased at different degree.
