摘要
运用Ｅｂｅｒｈａｒｔ－Ｒｕｓｅｌ品种稳定性分析模型，对我国１９８１年、１９８３年两次种源试验共引进的１９个火炬松种源的遗传稳定性及生长的立地生产力进行了评价，结果表明：（１）帕可塔可、卡尔斯顿、缺尼特、利文斯通、乔治城和琼斯等６个种源为丰产稳定型种源，适合于各种立地条件类型生长，且能高产；纳索、埃文斯和马里恩等３个种源为丰产不稳定型种源，适应于特定的立地条件类型，且能配合立地条件的改善，充分发挥其丰产性。（２）火炬松在我国川东，贵东的低山丘陵地区有着巨大的发展前途。（３）今后在火炬松造林生产中，在重视优良种源选择的同时，必须更重视造林地点的选择，并注重造林地的改良与管理，才能充分发挥优良种源的潜力。
The EberhartRusell stability analysis method has been used to evaluate the genotypic stability and site productivity of 19 loblolly pine provenances. The results of this study showed that:(1)6 provenances including Pasquotank N C,Charleston S C,trinity T X,Livingston L A,Georgetown S C and Junes M S were found to have high productivity,stability and wide adaptation. There are three provenances (Nassau F L,Evans G A,Marion F L) which were found to have the high productivity,low stability and could grow at sites specially appointed. (2)Loblolly pine can have a great development potential at low mountain and hilly regions in eastern parts of Sichuan and Guizhou. (3)In order to bring the superior provenances into full play in the afforestation in our country,more attention should be paid to the selection,improvment and management of the planting site besides the superior provenances selection.
