Camptotheca acuminata seedlings could tolerate 15% PEGgooo simulated drought stress during short time but the physiology was severe disturbance. CPT content was ascend under 10% PEGgooo drought stress condition that has important application purport.

• 本文研究结果表明:喜树幼苗能够忍耐短时间的15%25PEG_(8000)干旱胁迫,但生理严重紊乱,在10%25PEG_(8000)干旱胁迫下,喜树碱含量表达上升具有重要的应用意义。
