摘　　要：研究马铃薯试管薯休眠的破除及内源激素含量的变化,以期为生产上试管薯休眠破除的方式提供参考。以收获15 d的薯引1号试管薯为材料,应用赤霉素和Rindite处理破除其休眠。在打破休眠过程中,测定试管薯的休眠强度、休眠幅度和内源激素含量的变化。结果表明,10～40 mg的赤霉素和体积分数2%的Rindite都可以缩短马铃薯的休眠期,Rindite可以缩短休眠强度21 d,赤霉素可以缩短休眠强度9～14 d。不同的处理解除休眠时,内源激素含量的变化趋势不同,整体上赤霉素处理和Rindite处理的GA含量高于对照。The release of the dormancy of potato microtuber and the changes of intrinsic hormones were studied to provide information for release of dormancy of potato microtuber in production and scientific research.Potato microtubers were treated with gibberellic acid and Rindite to investigate their effect on dormancy release.The dormancy time,sprouting time,intrinsic hormones were measured in this experiment. The result showed that 10-40 mg/L gibberellic acid could shorten dormancy time by 9-14 days,and Rindite reduced dormancy time by 21 days.The dynamic changes in the contents of intrinsic hormones were different in the three treatments.And in whole the GA contents in the gibberellic acid treatment and the Rindite treatment were higher than that of the control.
