中文摘要:

在油葵灌浆期,采用25%PEG-6000对从内蒙古油葵主产区搜集到的30个杂交油葵品种(系)叶片进行模拟干旱胁迫处理,测定分析与抗旱性有关的叶片相对电导率(REC)、叶片相对含水量(RWC)、超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)、游离脯氨酸(Pro)等6项生理生化指标,综合比较其抗旱性能,运用隶属函数法分类,并通过聚类分析加以验证,隶属函数与聚类分析分类相同程度为76.67%。抗旱型共分为四类:强抗型、抗旱型、中抗型、弱抗型。强抗型共有5个品种,分别为:康地5号、AGR、内葵杂3号、澳葵62和白葵杂9号。

英文摘要:

30 hybrid oil sunflower varieties (series)which were widely planted in Inner Mongolia’s main producing area were used as materials in this experiment. At filling stage, 25% PEG6000 was used on leaves for drought stress simulation and 6 indexes (REC, RWC, SOD, POD, CAT and Pro)relating to drought-resistant characteristics were ana-lyzed. The synthetical drought resistance was estimated by membership function method and validated by clustering analysis, and the similarity degree of these two methods was 76.67 %. The drought-resistant types of the 30 cultivars were divided into 4 types in the estimated result, and they were separately strong resistance, resistance , middle resistance and weak resistance. There were 5 cultivars in the type of strong resistance, namely KD5, ACR, NKZ3, AK62 and BKZ9.
