Abstract:
Waterlogging is one of natural disasters affected the yield and quality of soybean adversely.Soybean is very sensitive to waterlogging at seedling,an detailed understanding on changes of root morphology and foliar physiological indexes under waterlogging stress will facilitate the screening of varieties resistant to waterlogging.In this study,10 soybean varieties were tested under artificial waterlogging for 7 days in double pots at seedling stage to research the changes of root morphology and foliar physiological indexes.There were significant differences between varieties for tested traits.Compared with the intolerant varieties,tolerant varieties had more adventitious roots and root nodules,developed better aerenchyma,and had lower relative conductivity,malondialdehyde and proline content in leaves.
