杨树品种过氧化物同工酶分析

Analysis of Poplar Varieties’ Peroxisom Isozyme

分析了22个杨树品种的过氧化物同工酶，调查了形态性状。杨树过氧化物同工酶的酶谱特征与形态表现基本一致。杂种过氧化物同工酶同时表现出父母双亲的谱带，验证了杂种核遗传物质来自父本和母本的事实。来自同一对亲本的正反交杂种同工酶谱存在差异，说明过氧化物同工酶体现了细胞质遗传，也就是母性遗传特征。

poplar varieties were determined on peroxisome isozyme and morphology. There is compatibility between zymogram of poplar’s peroxisom isozyme and their phenotype .Parants’peroxisom isozyme zymogram were displayed in hybrid at the same time .This confirm that hybrid’s hereditary matter come from its parants.Peroxisom isozyme expressed cytoplasmic inheritance because reciprocal cross hybrids’zymogram is different.
