Adaptation of Legume Seeds to Waterlogging at Germination

Legume seeds are often sown on standing rice crops a few weeks before harvest (relay cropping). Seeds cannot germinate in waterlogged soil under relay sowing as oxygen is depleted. However, may survive waterlogging if the can initiate anaerobic respiration, have large seed reserve such carbohydrates, perform slow water uptake during imbibition and small size. An example of crop that respiration rice. The embryo use an alcoholic fermentation pathway from carbohydrates to produce enough energy germinate. In legumes, with rate were more tolerant than rapid rate. This likely due low rates having less electrolyte leakage germination waterlogging. A amount remain surface soil.
