The experimental result shows that sprout index,sprout tendency,germinant percentage,MDA,electrical conductivity,activation ofcatalyses(CAT)and peroxidase(POD)offivevarieties artificial aged cottonseedare remarkably different.

• 为探讨老化种子活力与其生理性状的相关性；以5个人工老化的棉花品种为材料进行发芽试验；分别测定其种子发芽指数、发芽势、发芽率和幼苗的电导率、MDA(丙二醛)含量、CAT(过氧化氢酶)及POD(过氧化物酶)活性.
