外源影响因素对黄芪植株折干率的影响

Effect of External Factors on Drying Rate of Astragalus Plant

目的:探究外源影响因素对黄芪植株折干率的影响。方法:利用正交试验设计,测定黄芪植株折干率,进行方差分析和外源影响因素因素影响的多重比较。结果:对根折干率影响的最佳处理组合是用土豆培养基溶液处理黄芪植株的地上部位或者地下部位12 d,对茎折干率影响的最佳处理组合是用硝酸银溶液处理黄芪植株地上部分或者地下部分12 d,对叶折干率影响的最佳处理组合是用硝酸银溶液处理黄芪植株地上部分或者地下部分9 d。结论:采用该试验和分析方法研究外源影响因素对黄芪植株折干率的影响具有可行性。

Objective： To probe the effect of elicitor on drying rate of Astragalus plant. Methods： Use the or- thogonal experiment design. The drying rate of Astragalus plant was measured. Analyze the variance and make multiple comparisons of influencing factors of elicitor. Results ： The best combination of the drying rate of root, stem and leaf was to use PDA, silver nitrate and silver nitrate ,and the optimum processing time was 12 days, 12 days and 9 days,and the best processing part was root or acrial part. Conclusion： Using this test and analy- sis method to study on the effect of elicitor on drying rate of Astragalus plant is feasible.
