本项研究在长白落叶松全分布区范围内选择了9个试点和10个采种点。通过10年生种源子代生长性状的多点联合分析、稳定性分析、种源原产地与试验地间距的相关分析等,研究结果:①长白落叶松种源与参试点的互作效应达到了极显著的水平,体现了种源对环境条件的适应程度。10个参试种源可划分为三种类型,即高产稳产型——小北湖种源;低产稳产型——白河、和龙、天桥岭种源;中产稳产型——大海林、穆棱、鸡西、白刀山、大石头、露水河种源。②种源原产地与试验地距离间的相关分析表明,当地种源并非最好,用种要注意种子来源。③小北湖种源为高产稳产型种源,可在长白落叶松的适生范围进行推广,特别在尚无种源试验的地区,从该地区调种,增产的把握性较大。
In this research, 9 pilot sites and 10 seed sites were selected in the whole range of Larix olgensis. Through the multi-point joint analysis of growth traits of 10-year-old progeny progeny, the stability analysis and the correlation analysis of provenance and test spacing, the results are as follows: ① The interaction effect between Provenance and Parameter of Provenance The extremely significant level reflects the degree of adaptation of provenances to environmental conditions. The ten participating provenances can be divided into three types, that is, the high and stable yield type - the source of the Xiaobeihu Lake; the low and stable yield type - Baihe, Helong and Tianqiao Ridges provenance; the middle and stable yield type - Da Hailin, Muling, Jixi, Baodian Hill, a large stone, dew water source. (2) The correlation analysis of provenance and experiment distance shows that the local provenance is not the best, and the seed should pay attention to the seed source. ③ The provenance of Xiaobeihu is a provenance with high and stable yield, which can be popularized in the suitable range of Larix olgensis. Especially in the areas without provenance test, it is more controllable to increase the yield from the area.
