杉木种内杂交过氧化物酶同工酶酶谱分析

Analysis on Intraspecific Hybridization of Chinese Fir by Deroxidase lsozymes Zymogram

过氧化物酶同工酶酶谱分析结果表明，杉木亲本因来源、表型不同，同工酶酶谱存在一定差异。不同杂交种Ｆ１代同工酶酶谱一般倾向于母本，同时受双亲双重作用的影响。若在酶谱扫描曲线中出现峰值或峰面超双亲的酶带，有望得到优势杂交种（Ｆ１）。

Analysis on peroxidase isozymes zymogram resulted that isodynamic enzyme zymogram had difference because of different provenance、phenotype of Chinese fir P. Generally, F1 isozymes zymogram was tendentious to female parent, meanwhile, was influenced by two-parents. If scanning curve of zymogram had peak or kurtosis was higher than that of two-parents, superior hybrid could be obtained.
