摘要：通过人工模拟低温的方法确定-22℃萌芽率为杂交榛抗寒性的衡量指标,用相关分析确定评价杂交榛抗寒性的5个指标,用主成分分析法将5个指标转化为综合的主成分,确定指标权重,建立评价体系,再结合隶属度函数值求得杂交榛各无性系抗寒性的综合指数。根据综合指数的抗寒性排序为:84-349>81-23>85-127>B-3>84-69>84-545>81-9>83-33>84-1>84-72>84-254>84-48>84-402>84-237>82-11>84-226>B-21>84-572。通过聚类分析,将杂交榛抗寒性划分为4类:84-349、81-23和85-127为一类,其抗寒性最强;B-3、84-69、84-545、81-9、83-33和84-1为一类,抗寒性较强;84-72、84-254、84-48、84-402、84-237、82-11、84-226和B-21为一类,抗寒性较弱;84-572为一类,其抗寒性最差。
Germination rate of Hybrid Hazelnut, at - 22 ~C was determined as a judging indicator of cold hardiness with the method of artifical simulation of low-temperature. Correlation analysis was used to select, five indicators for cold resistance assessment of different Hybrid Hazelnut, and the indicatiors were further converted to integrated index by principle component analysis, with their weights determined for establishing the assessment system. Integrated index value of cold resistance of each variety was obtained based on the weight and its function value. The cold resistance order was 84 - 349 〉 81 - 23 〉 85 - 127 〉 B-3〉84-69〉84-545〉81-9〉83-33〉84- 1〉84-72〉84-254〉84-48〉84-402〉84-237〉82- 11〉84- 226 〉 B - 21 〉 84 - 572. These varieties of Hybrid Hazelnut could be divided into 4 groups by cluster analysis. 84 - 349,81 - 23 and 85 - 127 had the strong cold resistance, B - 3,84 - 69,84 - 545,81 - 9,83 - 33 and 84 - 1 had medium cold resistance, 84- 72,84- 254,84 - 48,84 - 402,84 - 237,82 - 11,84 - 226 and B - 21 had poor cold resistance, 84 - 572 was the poorest.
