摘要：

用微量元素钴处理常规早稻中早39种子，可以提高其萌发能力。尽管对最终发芽率没有影响，但平均发芽天数（MGT）减少48.0%，发芽指数（GI）提高53.1%，发芽势增加12.88倍。同时，用钴引发处理的种子MGT和发芽势显著优于水引发处理。

Abstract:

Seed priming of Zhongzao39 with cobalt improved the germination ability. In the study, MGT, GI and germination energy were significantly improved, although it had no significant effects on the final germination rate. MGT was decreased by 48.0%, GI was increased by 53.1% and germination energy was increased 12.88 times compared with the control. Meanwhile, MGT and germination energy under cobalt priming were better than those under hydro-priming.
