摘要: 以服务于科罗拉多冷杉(Abies concolor)的引种工作为目的, 以科罗拉多冷杉的9个种源半年生幼苗为材料, 对其进行了模拟干旱处理, 测定了抗旱性的相关理化指标, 并与同样处理下的我国本土冷杉辽东冷杉(A. holophyl la)、峨嵋冷杉(A.squamata)及鳞皮冷杉(A. fabric)半年生幼苗的对应指标作比较分析, 估测了科罗拉多冷杉在我国的适生范围。

Abstract: To investigate the successful introduction of Abies concolor in an area, we surveyed several indices representing drought resistance under simulated conditions of drought. We used 6-month-old seedlings of nine provenances of A. concolor and three species of domestic firs: A. holophylla, A. fabric and A. squamata. Results were analyzed for determining the best area for growth of A. concolor.

Key words: Abies concolor, Abies fabric, Abies holophylla, Abies squamata, drought resistance
