摘要: 在黑龙江、吉林和辽宁3省7个试验点对杂种落叶松13个处理播种育苗,用Eberhart和Russell模型等5种方法进行苗期稳定性分析,并筛选生长好且稳定性高的处理。结果表明,1年生和2年生高生长表现出极显著的正相关,Pearson和Spearman 相关系数分别为0.535和0.536,2年生各地点处理间均差异极显著(P<0.01),各地生长较快的家系:草河口为日本落叶松Larrix kaempferi 5 兴安落叶松Larrix gmelinii 12,兴安落叶松9 日本落叶松76-2;错海为日本落叶松5 长白落叶松Larrix olgensis77-3,日本落叶松5 长白落叶松78-3;富锦为兴安落叶松9 日本落叶松76-2,兴安落叶松5 兴安落叶松9;吉林为兴安落叶松12 兴安落叶松2,兴安落叶松7 日本落叶松77-2;林口为兴安落叶松12 兴安落叶松2,兴安落叶松5 兴安落叶松9;尚志为日本落叶松5 兴安落叶松9,日本落叶松5 长白落叶松77-3;铁力为兴安落叶松5 兴安落叶松9,兴安落叶松7 日本落叶松77-2。AMMI模型方差分析表明,处理间、地点间以及处理 地点差异极显著(P<0.01),方差分量分别为16.00%,56.25%,27.75%。AMMI模型、George模型和高稳系数法适合评价苗期高生长的稳定性。家系日本落叶松5 长白落叶松78-3,日本落叶松11 兴安落叶松2,兴安落叶松9 日本落叶松76-2和兴安落叶松5 兴安落叶松9生长好且稳定性高,兴安落叶松12 兴安落叶松2,日本落叶松5 兴安落叶松9,日本落叶松5 长白落叶松77-3和日本落叶松3 兴安落叶松9家系在部分地区生长好。图1表6参13Abstract: Thirteen treatments of hybrid larch (Larix spp.) were sown and raised in nurseries at seven sites in Heilongjiang,Jilin,and Liaoning Provinces. Pearsons and Spearmans correlation analyses between one-year old and two-year old trees were conducted. Also,seedling stage stability was analyzed,and treatments with high stability and good growth were tested with five models:Eberhart Russell,the additive main-effect and multiplicative interaction(AMMI),the George C. C. Tai,HSC,and Shukla. Results showed significant positive correlations between one-year old and two-year old for Pearsons(r =0.535) and Spearmans (r = 0.536) correlation analyses. For two-year old trees,using the AMMI ANOVA,differents of treatments at each location were extremely significant(P<0.01) with variance components for treatments = 16.00% (P<0.01),locations = 56.25%(P<0.01),and treatment location = 27.75%(P<0.01). Four treatments (Larix kaempferi 5 L. olgensis 78-3,L. gmelinii 9 L. kaempferi 76-2,L. kaempferi 11 L. gmelinii 2,and L. gmelinii 5 L. gmelinii 9) showed good growth and high stability;whereas four treatments(L. gmelinii 12 L. gmelinii 2,L. kaempferi 5 L. gmelinii 9,L. kaempferi 3 L. gmelinii 9,and L. kaempferi 5 L. olgensis 77-3) grew well in some areas.[Ch,1 fig. 6 tab. 13 ref.]
