摘要
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 first provenance test of Elaeocarpus sylvestris was carried out in three nurseries among 15 provenances in Jiangxi. The genetic variations of Elaeocarpus sylvestris were studied based on the investigation in one-year-old seedling traits and wood traits of natual trees from different provenances. The result showed that there were very significant differences among provenances in seedling height, diameter biomass and some other wood traits. The differences are mainly controlled by genetic factors. Rongnan, Quannan, Xinfeng and Shuichuan Provenances are better than the others. All this provides a preliminary basis for provenance selection of Elaeocarpus sylvestris.
