摘    要:以冬凌草的分枝数、单墩叶重及叶中冬凌草甲素的含量作为冬凌草药材产量和质量的评价指标,确定了河南淇县野生冬凌草和湖北广水、武汉野转家种冬凌草的最佳采收期,并分析了气象因素对冬凌草药材质量和产量的影响。结果表明:气象因素对引种地与原产地冬凌草的质量没有明显影响,药材叶中冬凌草甲素含量均在6月份左右达到峰值且十分接近;但气象因素对冬凌草产量则有影响,气候不同导致引种地野转家种药材的分枝数比原产地野生药材多2~4倍。综合质量和产量的考察结果,冬凌草的最佳采收期应定在其开花前,引种地武汉宜定在6月份,引种地广水宜定在6~7月份,原产地河南淇县宜定在6~8月份。

关 键 词:冬凌草  冬凌草甲素  气象因素  采收期

Abstract:To find out the optimum harvest time for wild Isodon rubenscens in Qi County of Henan Province and introduced in Wuhan , Guangshui of Hubei Province, we evaluated the yield and quality of I.rubenscens by the number of ramification, weight of leaves and content of rubescensine A of per-bundle plant. In addition, the effects of climate factors on yield and quality of I.rubenscens were analyzed. The results indicate that the effect of climate factors on the quality of I.rubenscens is not prominent, the content of rubescensine A in leaves of I.rubenscens in June reach approximate peak value in three areas. But climate factors have an effect on the yield of I.rubenscens, some of these factors can lead to the number of ramification on the plant in introduction areas is upwards to 2-4 times than the original area. To analysis all research results of the quality and yield of I.rubenscens, the optimum harvest time of I.rubenscens should be fixed ahead florescence. Therefore, the optimum harvest time of I.rubenscens is fixed from June to July in the introduced area-Guangshui of Hubei Province, and from June to August in the original area-Qi County of Henan Province. The studies can provide scientific basis for the Good Agriculture Practice of I.rubenscens.
Keywords:Isodon rubenscens  Rubescensine A  Climate factors  Harvest time
