摘要
通过对铜川焦坪林场油松母树林母树形态特征遗传变异的研究,根据树皮颜色和开裂方式等特征将油松划分为灰色纵裂型、灰色块裂型、灰色片裂型、黄色纵裂型、黄色片裂型与黑皮型6种形态类型,不同类型在经济性状、子代幼苗生长量、硝酸还原酶活力方面均存在显著差异。其中,黄色纵裂型、灰色纵裂型、黄色片裂型为优良类型。
Based on the study of morphological characteristics and genetic variation of the seed plants of Pinus tabulaeformis in Jiaoping forest farm,Tongchuan City,Shaanxi Province,China,P.tabulaeformis was divided into 6 types for the bark color and bark crack： gray longitudinal crackle type,gray chipped type,gray piece crackle type,yellow longitudinal type,yellow piece crackle type and black type.Significant differences existed among different types of morphological traits in economy,between offspring seedling growth and nitrate reductase.And yellow longitudinal type,gray longitudinal type,yellow piece crack type were considered to be superior types.
