| 摘 要： | 以长白落叶松、兴安落叶松、樟子松、红松、红皮云杉、胡桃楸、水曲柳7个主要用材树种的种源选择进行了全面地、系统地、综合地分析与总结。主要对各树种的早期选择,种源遗传稳定性研究及最佳种源选择等3个方面进行研究。分析结果:种源选择不仅为各造林地区提供了最佳种源,而且也为今后各树种的遗传改良、种子调拔、良种基地建设提供了可靠的依据。

| Abstract: | On the basis of the study on the geographic provenance of seven main tree species Larix olgensis L. gmelini, Pinus sylvestris var. mongolica, P. koraiensis, Picea koraiensis. Fraxinus rnandshuurica and Juglans mandshurica, this paper makes a summary of the provenancs selection to above tree species systematically and comprehensively. It mainly includes the study on the early stage selection and so on, thus the results not only provide the best provenance for each afforested area, but also supply us some reliable base for the genetic improvement, seed allotion and good seed source construction for above tree species. |
