Study on the Reproductive Biological Characteristics of Valeriana officinalis L. var. latifolia Miq.

This paper reports natural growth course of Valeriana officinalis L.var.latifolia Miq.,an important medicinal plant and the statistic analysis results of pollination experiment.There are prominent difference on the kilo grain weight of the achenia between wild and tame fields under the same pollination circumstance.While in the same background of planting and running,there are prominent difference on the burgeon rates of the achenia between beekeeping and no-bees plots,even the former is about 4 size higher than the latter.By artificially culturing and increasing the number of pollination medium,the problem that the low burgeon rates and the tinpot quality of the achenia will be settled.Thereby it is possible to culture this plant in large-scale and realize the sustainable usage of its resource.
