Abstract Taking 2 melon（Cucumis melo L.）lines T106 and T241 with significantly differences in flood-resistance as experimental materials，this paper analyzes the effects of flood stress and flood relieve on photosynthetic pigments and photosynthesis character of melon seedling．The results indicated that under extended time of flood stress， Chla，Chlb，Chl（a+b），Car，net photosynthetic rate，transpiration rate，stoma conductivity，inner cellular CO2 concentration of these 2 melon lines all decreased．The decreasing extent of T106 was lower than that of T241. In the same flooded duration，the indexes of T106 were all higher than T241．When flood was relieved，the indexes of 2 melon lines all increased，and the increasing extent of T106 was larger than T241.
