摘要：

An inhibitor was isolated from the secreted mucilage of Narcissus tazetta L. bulbs. Based on X-ray analysis, the inhibitor was identified as narciclasine (NCS), an Amaryllidaceae alkaloid. NCS inhibited seed germination and seedling growth of rice and Chinese cabbage in a dose-dependent manner. NCS interacted with plant hormones in some physiological responses. Indole-3-acetic acid could riot overcome the inhibition of elongation of wheat coleoptile sections caused by NCS. NCS suppressed the gibberellin-induced alpha-amylase production in barley seeds and cytokinin-induced expansion and greening of excised radish cotyledons. (C) 1998 Elsevier Science Ireland Ltd.
