| 摘 要： | 采用聚丙烯酰胺凝胶垂直板电泳法对西南桦(BetulaalnoidesBuch．-Ham．ex．D．Don)6个种源苗期酯酶同工酶，11个种源苗期过氧化物同工酶比较分析表明西南桦不同种源间在酯酶、过氧化物同工酶谱带数、迁移率(Rf值)方面存在差异；同一种源内不同个体间在酯酶、过氧化物同工酶谱带数、迁移率(Rf值)方面存在明显差异。这一结果进一步表明西南桦在群体、个体上存在广泛遗传变异。

| Abstract: | Leaves of Betula alnoides as sample, esterase isozyme of seedlings from 6 provenance and peroxidase isozyme of seedlings from 11 provenance were tested by means of vertical slab polyacrylamide gel electrophoresis.?The result shows that the patterns and Rf values of two isozymes of the seedlings from different provenance are different greatly and those of the individuals from same provenance are also different.? This result indicates further that there exist broad inheritance both in populations and in individuals of Betula alnoides.? |
