Abstract
Priming effects were studied on seed germination and vigor of sweet corn seeds using water priming,KNO3,KNO3+KH2PO4.The results showed that effects of germination rate weren't improved by priming,but they could promote coleoptile and seedling growth and vigor;the impact on coleoptile and seedling growth followed by:KNO3+KH2PO4 priming KNO3 priming water priming;the impact on seed vigor followed by: KNO3+KH2PO4 priming water priming KNO3 priming.The best priming effect was obtained at the treatment of 0.5%～1.0% KNO3+KH2PO4 priming,soaking for 12 h,could promote coleoptile length,seedling growth and vogor,by 4.76 cm,0.85 g,46.59 respectively,and they were increased by 73.72%,31.09%,17.49% than that in the natural seeds.
