The protocol for the detections of all the AIV isolates, the H5-subtype and the optimization of reactions were studied with a H5-subtype reference isolate BSG1. A 229bp-band of AIV specific and a 380bp-band of H5 subtype specific were amplified individually with the designed primers of AIV specific and H5-subtype specific respectively by the developed RT-PCR technique from isolate BSG1. A double-PCR was also developed which can detect all the AIVs and identify the H5-subtype AIVs. The results of specificity experiment showed that there was no specific band could be amplified with the samples of Newcastle disease virus, infectious bronchitis virus, infectious laryngotracheitis virus, egg drop syndrome virus and infectious bursal disease virus.

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.
