| 中文摘要: |
| 以7个区试甘蔗品种为材料、采用盆栽法进行抗旱处理、测定绿叶率尧株高等形态指标以及质膜渗透性尧
叶绿素相对含量尧脯氨酸含量尧丙二醛含量和超氧化物歧化酶活性等生理指标。采用主成分分析尧模糊隶属函数对多
指标进行综合分析、全面评价7 个甘蔗品种的抗旱性。结果表明、3 个综合主成分可达到甘蔗抗旱性94.943%的原始
数据信息量；利用系统聚类分析、将7 个参试品种分为3 类、其中、ROC22 和云蔗06-407 表现出较强的抗旱性、福农
39 和粤糖55 表现为中度抗旱性、ROC16尧粤甘26 和柳城05-136 表现出较弱的抗旱性。 |

| varieties. Seven indexes closely related to the drought tolerance were measured, including rate of green
leaves, plant height and other morphological indicators as well as the plasma membrance permeablitiy, chlorophyll content,
proline content, MDA content and superoxide dismutase activity and other physiological indicators. Using principal
component analysis, fuzzy membership functions for multi-index comprehensive analysis to evaluate the drought resistance
of the seven sugarcane varieties. The results showed that three principal components could achieve 94.943% of the original
amount of information. By the cluster analysis, the seven tested varieties were divided into three categories. ROC22 and
Yunzhe06-407 performanced strong drought resistance, Funong39 and Yuetang55 showed moderate drought resistance,
ROC16, Yuegan26 and liucheng05-136 showed weak drought resistance |
