| 摘 要： | 多效唑浸种对水稻幼苗、根和芽的生长有明显的抑制作用 ,且使水稻幼苗的干重、鲜重减少 ,而干物质百分率提高单独使用DMSO(二甲亚矾 )对水稻幼苗、根和芽生长稍有促进作用 ,使水稻根、芽干重和鲜重降低 ,而干物质百分率提高 .以DMSO作为溶剂溶解多效唑可增强多效唑对水稻幼苗生长的抑制作用 ,尤其对水稻根的抑制最为明显 ,质量分数为 5 0×10 -6多效唑DMSO溶液的抑制作用相当于质量分数为 5 0× 10 -6多效唑的作用

| Abstract: | Paclobutrazol seed soaking plays an obvious controlling role in the growth of riceseedling, root and sprout. Paclobutrazol seed soaking makes both the dry weight and fresh weightof rice seedling reduced while the percentage of dry substance is increased. Using DMSO aloneslightly accelerates the growth of rice seedling, root and sprout. DMSO as a solvent dissolvingpaclobutrazol can strengthen the control of the growth of rice seedling, especially the control ofrice root. |
