首次对15个山杜英种源的苗期性状进行分析,并对采种母树的木材材性进行测定,结果表明:种源间的苗高、地径、生物量以及木材基本密度差异达极显著水平,这些差异主要与遗传因素的制约有关。并初步筛选出龙南、全南、信丰、遂川等几个表现较好的种源,为今后山杜英的进一步育种研究提供了初步的理论依据。
The seedling traits of 15 provenances were analyzed for the first time. The wood properties of the seed trees were measured. The results showed that the differences of seedling height, diameter, biomass and wood basic density between provenances reached extremely significant levels, These differences are mainly related to genetic constraints. And screened several provenances, such as Longnan, Quannan, Xinfeng, Suichuan and so on, which provided a preliminary theoretical basis for the further breeding research of Shanmuying in the future.
