摘要
为了探明不同种源岩白菜的农艺性状与生物量及有效成分间的相关性,为岩白菜的良种选育和永续利用提供理论依据。观测了24份岩白菜种源的7个农艺性状和3个生物量性状,并利用HPLC法测定岩白菜的有效成分含量。结果表明:株根状茎干重与株干重、株高、根状茎直径间均呈极显著正相关关系(P<0.01);株叶片干重与株高呈显著正相关关系(P<0.05),与根状茎直径极显著正相关关系(P<0.01)。岩白菜素单株产量与根状茎直径间呈显著正相关关系(P<0.05),与其他农艺性状间相关性不显著;叶片中熊果苷的含量与株高呈显著负相关(P<0.05),与其他农艺性状间呈负相关,但没有达到显著水平;而根状茎中岩白菜素的含量和熊果苷的单株产量与7个农艺性状间相关性均不强。株高和根状茎直径是岩白菜选育种时需重点关注的2个农艺性状。
In order to provide a theory basis for breeding and sustainable utilization of Bergenia purpurascens,the correlations between agronomic traits and biomass and effective components in different resources of B.purpurascens had been discussed.7 agronomic characters and 3 biomass characters from 24 resources were observed,and the contents of effective component were determined in the method of HPLC.It was showed that there was a very significant positive correlation(P0.01) between dry weight of rhizomes per plant,total dry weight of plant and plant height,diameter of rhizomes.A significant positive correlation(P0.05) between dry weight of leaves per plant and plant height and a very significant positive correlation(P0.01) between dry weight of leaves per plant and diameter of rhizomes per plant were found too.There also was a significant positive correlation(P0.05) between the yield of bergenin per plant and diameter of rhizomes,although there was no significant correlation between the yield of bergenin per plant and other agronomic traits.A significant negative correlation(P0.05) between content of arbutin in the leaves and plant height was found.Although there was no significant negative correlation between content of arbutin in leaves and other agronomic traits,however,a significant negative correlation trend was found between them.No significant correlation between content of bergenin in the rhizomes,the yield of arbutin in the leaves and 7 agronomic traits was found.Conclusion:Plant height and diameter of rhizomes are the two important agronomic traits for screening and breeding new varieties of B.purpurascens.
