Abstract：The seeds of maize (Zea mays L.)variety Zhengdan 958 were used to study the change of ul-traweak luminescence (UWL)intensity and its relationship with seed vigor,relative electric conductivity and ATP content during artificial aging.The results indicated that the germination percentage,germination poten-tial,germination index,UWL intensity and ATP content decreased gradually,while the relative electric con-ductivity increased with the prolongation of artificial aging.The correlation analysis showed that UWL intensity was significantly positively correlated with germination percentage,germination potential,germination index and ATP content,while significantly negatively correlated with relative electric conductivity.It was concluded that UWL was closely related to the energy level symbolized by ATP content,and as a fast nondestructive physical indicator with better sensitivity,it could be applied into the study of seed vigor nondestructive testing.
