目的　了解湖北省恩施土家族苗族自治州地区玄参两个主要栽培品种的差异。方法　采用对不同栽培品种的玄参子芽按颜色、数量、重量、大小进行分级 ,对出苗率及产量等比较。结果　两个品种同一级别的子芽出苗率无明显差异 ,一、二级子芽的出苗率 ,米玄参比毛玄参高 5 % ,三级子芽出苗率相同 ,各级子芽白色的均优于紫色的 ;产量上米玄参高于毛玄参。结论　米玄参产量、商品率比毛玄参高。以白色子芽做繁殖材料优于紫色的

Study on Differences between Two Strains of Scrophularia ningpoensis Hemsl.Cultivated in Enshi

Objective To tell differences between two strains of Scrophularia ningpoensis Hemsl. cultivated in Enshi Tujia and Miao Autonomous Prefecture.Method By comparing sprouts of different strains in terms of color, amount, weight, size, seedling rate and output.Result Both strains of same rank showed no significant difference in seedling rate, but differ in: for rank one and two, seedling rate of Scrophularia ningpoensis Hemsl.(Mixuanshen) was 5 per cent higher than that of Scrophularia ningpoensis Hemsl.(Maoxuanshen); for rank three, seedling rates of both strains were the same; white sprouts of all ranks have a higher seedling rate than that of purple ones;Scrophularia ningpoensis Hemsl.(Mixuanshen) generally has a higher output than Scrophularia ningpoensis Hemsl.(Maoxuanshen).Conclusion Scrophularia ningpoensis Hemsl.(Mixuanshen) is superior to Scrophularia ningpoensis Hemsl.(Maoxuanshen) in output and merchantable nature; white sprouts play a better role than purple ones acting as propagation material.
