岩白菜的生物量和有效成分与农艺性状间的相关性分析

摘要：本文首次探讨了不同岩白菜种源的生物量和有效成份与主要农艺性状间的相关性，结果表明：株根状茎干重和株干重与株高、根状茎直径间均呈极显著正相关(P<0.01)；株叶片干重与株高呈显著正相关(P<0.05)，与根状茎直径极显著正相关(P<0.01)。岩白菜素株产与根状茎直径间呈显著正相关(P<0.05)，与其他农艺性状间相关性不显著；根状茎中岩白菜素的含量和熊果苷的株产与7个农艺性状间相关性均不显著；叶片中熊果苷的含量与株高呈显著负相关(P<0.05)，与其他农艺性状间相关性均不显著。株高和根状茎直径是岩白菜选育种时需重点关注的两个农艺性状。

Correlation analyses between biomass, active components and agronomic traits of Bergenia purpurascens

Abstract: The correlations between biomass, active components and agronomic traits of different resources of Bergenia purpurascens in Yunnan province were explored for the first time. It was showed that there was a very significant positive correlation (P<0.01) between dry weight of rhizomes per plant, total dry weight of plant and plant height, diameter of rhizomes. A significant positive correlation (P<0.05) between dry weight of leaves per plant and plant height and a very significant positive correlation (P<0.01) between dry weight of leaves per plant and diameter of rhizomes per plant were found too. There also was a significant positive correlation (P<0.05) 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. No significant correlation between content of bergenin in the rhizomes, the yield of arbutin in the leaves and 7 agronomic traits was found. A significant negative correlation (P<0.05) 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. Plant height and diameter of rhizomes are the two important agronomic traits for screening and breeding new varieties of B. purpurascens.
