3种甘草种子苗和根茎苗在同一生境下的生长差异

Growth differences of seed seedlings and rootstock seedlings for 3 kinds of Glycyrrhiza L.in the same habitat

在同一生境下用种子苗、根茎苗繁殖光果甘草(Glycyrrhiza glabra L.)、胀果甘草(Glycyrrhiza inflata Bat.)、乌拉尔甘草(Glycyrrhiza uralensis Fisch.),并对其地上部分(株高)和地下部分(根数、根粗、根茎数和根茎粗)进行比较研究。结果表明:(1)3种甘草地上部分、地下部分生长特征大部分种子苗优于根茎苗。(2)3种甘草生长特性表现不一致。在株高方面,种子苗和根茎苗均为胀果甘草表现最优;在根数方面,种子苗和根茎苗均为乌拉尔甘草最优;在根茎数和根粗方面,种子苗为乌拉尔甘草最优,根茎苗为胀果甘草最优;在根茎粗方面,种子苗为乌拉尔甘草最优,根茎苗为胀果甘草最优。(3)3种甘草种子苗、根茎苗根粗和根茎粗均与株高呈相关关系。

Under the same habitat Glycyrrhiza glabra 1., Glycyrrhiza inflata Bat., and Glycyrrhiza uralensis Fisch. were propagated by seed seedlings and rootstock seedling. Their aerial part （plant height） and underground part （root number, root diameter, rootstock number and rootstock diameter） were compared. The results showed that： （1） the growth features of aerial part and underground part of most seed seedling of three kinds of licorice were better than that of root seedlings. （2） the growth characteristic of three kinds of licorice were different. In terms of plant height, seed seedling and rootstock seedlings of Glycyrrhiza inflata were optimal; In terms of root number, seed seedling and rootstock seedlings of Glycyrrhiza uralensis were optimal; In terms of rootstock number and root diameter, seed seedling of Glycyrrhiza uralensis were optimal, rootstock seedlings of Glycyrrhiza inflata were optimal; In terms of rootstock diameter, seed seedling of Glycyrrhiza uralensis were optimal, rootstock seedling of Glycyrrhiza inflata were optimal. （3） the root diameter, rootstock diameter of seed seedlings and rootstock seedlings of three kinds of licorice were related to plant height.
