摘要:

采用核磁共振(NMR)技术,对我国黄连木分布区9个天然群体果实含油率进行取样测定。结果表明:果实、种子和果肉含油率分别为36.183%,26.594%,50.503%,不同群体间差异显著,群体平均表型分化系数达到92.08%,果实含油率存在地理变异。系统聚类分析将黄连木群体分为低变异中等含油率群体、低变异低含油率群体、高变异高含油群体3类。果实含油率与原产地的经度、纬度和生态梯度值的相关关系表明:黄连木果实含油率呈东北-西南由低到高的地理变异走向,经纬度高的地区黄连木果实含油率低于经纬度低的地区。种子和果肉含油率与生态因子也表现相似的变异趋势,但对生态因子的反映更为迟钝。

Abstract:

Fruit oil Content of 9 natural populations of Pistacia chinensis was investigated with Nuclear Magnetic Resonance (NMR) method. The result showed: content of oil in the fruit, seed and pulp was respectively 36.183%, 26.594% and 50503% of the total oil content. There was significant variance inthe oil content from different populations. The populations were classified into 3 groups by clustering analysis,and they were respectively lower variance and middle oil content of population, lower variance and low oil content of population, high variance and high oil content of population. Fruit oil content of P. chinensis existed a variation trend along southwest- northeast, the higher latitude and more east longitude, the more fruit oil content of P. chinensis. The oil content of seed and pulp had the same trend, though to a less degree, with ecological factors as the fruits did.
