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.

Key words: nuclear magnetic resonance, Pistacia chinensis, oil content, geographic variation
