摘　　要：应用数理统计方法从多角度对168个甘蔗品系的蔗苗螟害枯心率(2.47%～46.13%)与甘蔗成熟期健康蔗茎田间蔗汁锤度(18.2%～25.6%)的关系进行分析研究。结果表明:甘蔗苗期螟害枯心率的高低与甘蔗品系田间蔗汁锤度的高低没有显著关系。The field experiment for 168 sugarcane varieties was conducted to test the relationship between dead heart rate and sugarcane-juice brix. The relationship between the dead heart rate caused by the borer （from 2.47% to 46.13%） and the brix （from 18.2% to 25.6%） from the health mature sugarcanes was analyzed by statistics and multi-angle analysis. The results showed that there was no significant relationship between dead heart rate and the sugarcane-juice brix.
