播前在不通气水中浸泡种子,导致多种植物种子发芽率降低。然而,对降低发芽的机制却了解甚少。在浸泡期间,像乙醇、乙醛和CO_2作为无氧代谢的最终产物从种子和浸泡水的累积物中排放出来。在一项对水稻、莴苣、玉米、蚕豆和豌豆的研究中,种子浸泡期间排放的乙醇数量与随后的发芽率呈负相关(r= Sowing seeds in non-aerated water before sowing, resulting in reduced germination rate of many plant seeds. However, little is known about the mechanisms that reduce germination. During soaking, ethanol, acetaldehyde, and CO 2 are released as an end product of anaerobic metabolism from seed and submerged water accumulations. In a study of rice, lettuce, corn, broad bean and pea, the amount of ethanol emitted during seed soaking was inversely related to the subsequent germination rate (r =
