Eleven days old maize seedlings was treated with 2, 3 and 4 days of waterlogging followed by 2 days recovery in laboratory wherein the field condition, treatment of 4, 5 and 6 days of waterlogging followed by 2 days recovery was treated in 28 and 63 days of maize plant under the both laboratory and field situations. Porosity of root followed a decreasing trend with the increase in duration of waterlogging. However, 2 days of recovery period improved leaf porosity over their respective treatments of waterlogging in both the varieties. The improvement was however, more in Suwan than Ganga Safed-2.Not Availabl
