白杨派杨树杂种F_1代同工酶谱聚类分析

The Grouping and Analysis of Hybrid F_1 Individuals of Aspen by means of Isozyme Spectrography

经过氧化物酶和酯酶分离比较，选用过氧化物酶同工酶谱相似系数进行聚类，选择相似系数在０．９４～０．９１范围，将０１（６１１８×混合花粉）组合４２株杂种Ｆ１苗聚为２５类过氧化物酶类型，０２（６１１６×银白杨）组合２９株杂种Ｆ１苗聚为２３类，０６（６１１８×银白杨）组合３９株杂种苗聚为１９类。

Through separation and comparison of peroxidase and esterase,the similarity coefficients(0.94～0.91) of isozyme spectrogram of peroxidase were chosen for the classification of hybrid F1 individuals of arpen.42young trees of the hybrid F1 of combination 01(6118×mixed farina) were grouped into 25 peroxicase types;29 hybrid F1 trees of combination 02(6116×populus alba L.),23 types;and 39 trees of combination 06(6118×P.alba L.),19 type.
