摘　　要：用20种浙江天台山优势度明显的植物浸提液,从中筛选得到6种对气孔运动效果明显的植物,即醉鱼草、芒萁、马醉木、革命菜、常春藤和络石,研究了它们对蚕豆保卫细胞K+通道和微丝的调控作用。结果表明:马醉木浸提液可拮抗微丝解聚剂(CD)对微丝的解聚,芒萁浸提液中可能存在外向K+通道的激活剂,络石浸提液和常春藤浸提液可以激活内向K+通道,络石可以明显抑制外向K+通道。而醉鱼草、芒萁、马醉木浸提液对外向K+通道活化有一定的作用,但革命菜浸提液的调控效果不明显。Used the extracted solution of 20 plant population dominate species from Tiantai mount in Zhejiang province, and selected 6 plant species which apparently affected Vicia faba guard cell stomatal movements, namely Buddleja lindleyana, Dicranopteris pedata, Pieris japonica, Gynura crepidioides, Hedera helix and Trachelospermum jasminoides. The assay focused on how these 6 plant extracted solutions regulated K^＋ channels and microfilament in Vicia faba guard cell stomatal movements. The results indicated that Pieris japonica extracted solution could anti-cytochalasin D in filament diffusion, Dicranopteris pedata extracted solution might existed outward K^＋ channel activator, inward K^＋ channels could be activated by Trachelospermum jasminoides and Hedera helix extracted solutions, outward K^＋ channel could be inhabited by Trachelospermum jasminoides extracted solution apparently, and Buddleja lindleyana , Dicranopteris pedat , Pieris japonica toke part in outward K^＋ channel activated, but it was failed to identify the function of Gynura crepidioides extracted solution in regulating K^＋ channels and microfilament.
