摘要

目的：为商陆种质资源利用与优良品种选育提供依据。方法：收集全国主分布区商陆野生种质资源23份，考察其经纬度、海拔、农艺性状，用热浸法测定块根水溶性浸出物含量，用HPLC-ELSD法测定块根商陆皂苷甲含量，用DPS 6.55，Excel 2003软件进行单因素方差分析、相关性分析、主成分分析与聚类分析。结果：商陆不同种源间农艺性状存在显著差异（P<0.05），其中福建、广西种源生长势好，植株高大，茎粗，叶片大而多狭长，块根产量高；不同种源间水溶性浸出物、商陆皂苷甲含量也存在显著差异（P<0.05），2个成分变异规律相似，与种源地、经纬度、海拔、农艺性状存在相关性，其中陕西、浙江种源含量较高；与株高、茎粗、叶片长、叶片宽、叶柄长、块根纵径、块根横径、块根产量呈负相关关系，与根形指数、纬度、海拔呈正相关关系，与叶形指数、经度相关性较低；12个生长与成分性状指标可简化为5个主成分，累计贡献率达93.611 9%；23个种源可划分为5类。结论：高纬度、高海拔种植商陆有利于块根中水溶性浸出物与商陆皂苷甲含量积累；共筛选出5个农艺性状优良种源与4个高成分含量优良种源，可作为高产、优质商陆品种选育备选种质。

Abstract

Objective: To provide basis for utilizing germplasm resources and selecting superior varieties of Phytolacca acinosa. Method: Twenty-three wild germplasm resources of P. acinosa from the main distribution areas of China were collected

and their longitude

latitudeand agronomic traits were studied. Contents of water-soluble extractives and esculentoside A were determined by hot dipping and HPLC-ELSD methods respectively. The data obtained were analyzed with DPS 6.55 and Excel 2003 software by ANOVA and UPGMA methods. Result: There were significant differencesin agronomic traits among different germplasms of P. acinosa (P<0.05). Plants from Fujian and Guangxi showed superior agronomic characters and higher earthnut production. Moreover

there were significant differences in contents of water-soluble extractives and esculentoside A (P<0.05)

and plants from Shaanxi and Zhejiang were higher than others. The contents had a negative correlation with height of plant

diameter of stem

length and width of leaves

length of stipe

vertical and horizontal diameter of earthnut

production of earthnut

a positive correlation with earthnut index

latitude and altitude

and no significant correlation with leaf index and longitude. Conclusion: Plantation of P. acinosain high-latitude and high-altitude areas can enhance the accumulation of water-soluble extractives and esculentoside A. Five germplasms with superior agronomic traits and four germplasms with higher contents of water-soluble extractives and esculentoside A are selected

which could be alternative high-yield and high-quality germplasms of P. acinosa.
