摘要: 杉木叶腋中存在两种具再生能力的结构──受抑制的腋芽和保留分生组织。观察中未见到不定芽。受抑制的腋芽随着主茎的次生生长而发育成次生休眠芽。这两种结构是杉木萌芽更新的结构基础,同时也显示其营养繁殖能力。

Abstract: Suppressed axillary buds and persisting meristems,which show the regeneration ability were investigated in the axile of seedlings and sprouts of Chinese fir(Cunninghamia lanceolata(Lamb.)Hook). But adventitious buds were not observed in the same material.The suppressed axillary buds can develop into secondary dormant buds with the secondary growth of the main stems.Sprouts may arise from secondary dormant buds or suppressed axillary buds directly, and may also originate from persisting detached meristems by forming additional buds.Such axillary structures have profound significance to sprout regeneration of this coniferous species.

Key words: Chinese fir, Suppressed axillary buds, Persisting meristems, regeneration from sprouts
