Abstract:Seeds of Pinus armandii, collected from 6 different provenances, were studied. The result shows significant georaphical variation strongly correlated to the vegetation zones. Seeds produced from temperate steppe zone (Xunhua, Guyuan)and western subtropical evergreen broad-leaf forest zone (Huidong) were bigger, heavier and less dormant, even non-dormant, while those from warm temperate deciduous broad-leaf forest zone (Lantian) and eastern subtropical evergreen broad-leaf forest zone (Yichang, Jiangyou) were smaller, Lighter and more dormant. Oil content, fatty acid and amino acid compositions of decoated seeds also varied with their vegetation zones. Stratification for 20 days (at 0—5℃) proved to be effective, regardless of seeds’dormancy state.
