地黄常见品种“温85-5”性状变异研究

Study on Trait Variation of a Popular Cultivar"WEN85-5"of Rehmannia Glutinosa Libosoh.

目的:探究地黄常见品种"温85-5"性状变异规律。方法:观测比较4个样本的主要农艺性状,以梓醇、地黄多糖、水溶性浸出物为品质评价指标,对性状与品质进行相关性分析。结果:地黄品种"温85-5"的性状变异明显;随着药农自行留种年限的增加,地黄抗性、产量和品质均有不同程度的降低。结论:地黄品种"温85-5"的性状变异已经一定程度影响了地黄的产量和品质;药农自行留种5年以上的种栽应进行品种复壮或重新采用原种。

Objective： To explore the trait variation of a popular cultivar ‘WEN85-5’ of Rehmannia glutinosa Libosoh. . Method： Comparison of main traits of four ‘WEN85-5 ’ samples, Taking Catalpo, Polysaccharides and aqueous extracts as the evaluation indices of R. glutinosa. quality; The Correlation of Analysis on the main traits and quality. Result： The morphological variation of ‘WEN85-5’was significant; The species are bred,its traits are decreasing on the fertility,anti-disease and the quality With the increasing years. Conclusion： the variation of traits have influenced the yield and the quality of Redix Rehmanniae; The farmer should introduce the first cultivar or recover its traits.
