Water stress is one of the most important abiological stress to maize seedling .In this study, we arm to identify the sensitive stage of maize seedling to water stress and select the material which tolerance to flooding. And we use waterlogging tolerance index to identify the sensitive stage of maize seedling. we have studied 20 inbred lines of maize which seedlings under water stress in three stage. The result show that the three leave stage is the most obvious stage to flood stress. In addition, we have analyzed ten of the inbred lines to re-act the waterlogging tolerance index. The result show good re-action. And the result also show that waterlogging tolerance index is a credible index to select waterlogging tolerance materials in seedling.

涝渍是玉米苗期主要的非生物逆境胁迫之一；本试验通过对20份玉米自交系进行苗期的淹水对照试验，采用了三个处理时期，并利用耐渍系数作为指标进行敏感时期的鉴定，结果表明三叶一心期是淹水的相对最佳时期；同时利用其中10份自交系对耐渍系数的重演性进行了分析，结果表明其重演性很好；同时结果还表明耐渍系数是耐渍性鉴定的一个可靠指标。

The trial was designed by orthogonal L9 (3^4) of N, P, K nutrients and three levels respectively in this study. The effects of these nutrients and their levels on growth of seedling height and ground diameter of Agathis dammara were studied and the best fertilization method was determined. The results showed that the effects of high significant differences among different fertilization treatments through 1-8 months.
