采用生化遗传学的方法，对我国亚热带地区几个二倍体和四倍体野生鸭茅不同生育期的酯酶、过氧化物酶同功酶进行了比较研究。结果表明，鸭茅二倍体各品系之间、四倍体各品种（系）之间的同源性较高，遗传差异较小；二倍体与四倍体之间，酯酶、过氧化物酶同功酶等都有较大差异。
Using the methods of biochemical genetics, the esterase and peroxidase isozymes in different growth stages of several diploid and tetraploid wild Dactylis glomerata in subtropical regions of China were compared. The results showed that there was high homology among tetraploid varieties and tetraploids, but little genetic difference between diploid and tetraploid cultivars. Esterase and peroxidase Enzymes such as enzymes have greater differences.
