Poplar, a fast-growing species widely used outside its original area of distribution, was evaluated in the present study to verify its tolerance and hardening to waterlogging in anticipation of its implementation in rehabilitation practices for marginal lands subjected to flooding. Three water regimes were applied to the plants, grown in pots, with two clones (I-488 and D-64) with different sensitivities to flooding. These plants included a lot consisting of control plants (C), which were irrigated with good drainage, a non-preconditioned lot (NPr), and a third lot that was preconditioned to flooding (Pr). Furthermore, flooding was imposed on NPr and Pr plants by submerging pots up to 5 cm above the collar for 60 days followed by a 40-day recovery period. At the end of these two periods, shoot dry mass, foliar concentrations of certain ions, soluble sugars, starch and proline, and the relative electrolyte leakage were evaluated. The preconditioning treatment conferred different degrees of hardness on the treated plants compared with NPr plants. Our results revealed that high carbohydrate availability (soluble sugars and starch) is suggested to participate in sustaining membrane integrity which may affect the recuperative potential of Pr plants, notably those of clone I-488, from flooding damage.<\/p>\n","protected":false},"excerpt":{"rendered":"
