Phenotypic variation in seed cones and seeds of species and families in different provenances of Pinus tabulaeformis

Abstract: To reveal the regularities of cone and seed variation,the phenotypic traits of cones and seeds of seven species and 141 families in natural populations of Pinus tabulaeformis provenances of Shaanxi Province were analyzed. Statistical analyses,such as analysis of variance,correlation analysis among provenances and within families for a provenance of P. tabulaeformis,and genetic variation,were used. Result showed that significant differences were found between in provenances and in individuals within provenances in cone length(PPPPPPPP<0.05) negative correlation; and for cone and seed traits at a latitude,≥10 ℃ accumulated temperatures and the frost-free period were not significantly correlated. The variations of seed traits and the thousand-seed weight comply with annual mean temperature. The variations of cone width and seed width mainly follow the variation of altitude.
