Abstract

Germination of Panicum capillare L. caryopses induced by solutions of ethanol and ethyl ether was prevented by application of pressure >1 MPa during the period of exposure to the anesthetic. This effect of pressure indicates that germination is correlated with expansion at a site of anesthetic action in a cell membrane. The effects of several other anesthetics were measured on germination of P. capillare seeds. Ethanol, chloroform, and ethyl ether had the highest activity. Methanol and isopropanol were inactive. The effective compounds are thought to distribute preferentially to lipid-solution interfaces in cell membranes of the seeds.

摘要

在暴露于麻醉剂期间，应用压力 >1 MPa 可防止黍属颖果的发芽，该压力可防止乙醇和乙醚溶液诱导的黍属颖果发芽。这种压力效应表明，发芽与细胞膜中麻醉作用部位的膨胀有关。还测量了几种其他麻醉剂对黍属颖果种子发芽的影响。乙醇、氯仿和乙醚具有最高的活性。甲醇和异丙醇没有活性。这些有效化合物被认为优先分布在种子细胞膜的脂溶性界面中。
