杏树良种引种试验研究

采用多元统计分析方法对杏树良种引种试验结果进行了分析．首先用二元对比排序方法，确定了果形、色泽、大小、肉质、汁液、风味、杏仁的权重向量，从果形、色泽、大小等７方面对品质进行了评判，结果表明，唐汪川桃杏品质最优，兰州大接杏次之；然后利用相对欧氏距离计算了品质、抗寒性、丰产性的模糊优先比．表现优劣的顺序为：兰州大接杏＞安宁１８号＞华县大接杏＞唐汪川桃杏＞梅杏＞金妈妈＞猪皮水杏＞大偏头杏＞曹杏．

Introduction of Superior Species of Prunus armeniaca L. in Zhangye Prefecture of Gansu Province

This paper analyses the experimental results of introduction of Prunus armeniaca L. by using multivariate analysis. The weight vectors of shape, colour, size, pulp, juice, taste and kernel of Prunus armeniaca L, have been determined, and the quality of the apricot fruits have been appraised by means of dualistic comparing sequencing. The appraised results show that the quality of Tangwangchuantao apricot is best, that of Lanzhou Dajie apricotis next. The fuzzy priority ratio of quality,frost-resistance and high-yield of the introduced species has been calculated by using the relative distance as a parameter.The quality sequencing of the species is as follows:Lanzhou Dajie apricot>Anning 18 apricot>Huaxian Dajle apricot>Tangwangchuantao apricot>Mei apricot>Jinmama apricot>Zhupishui apricot>Dabiantou apricot and Cao apricot.
