摘要
通过对蔗苗枯心率及甘蔗产量构成因素跟踪调查分析,结果表明,蔗苗枯心率高低与甘蔗有效茎及茎径变化间存在相关性,与株高变化间相关性不明显。在一定枯心率范围内,枯心率与有效茎数呈正相关,与茎径呈负相关。
Tracking investigation of the dead heart rate of sugarcane and the sugarcane yield components was conducted. The results showed that the dead heart rate of sugarcane had a remarkable correlation with millable stalk numbers and stalk diameter, but there was no obvious relativity with stalk height. In a certain extent, there was a positive correlation between dead heart rate of seedling and effective stalk numbers, and a negative correlation with stalk diameter of sugarcane.
