Other claims from this paper (10)
- Intervention effect Salinity stress impaired cotton plant growth.
- Intervention effect Nitrate-fed cotton plants were less sensitive to salinity than ammonium-fed plants.
- Mechanism Superior root growth of nitrate-fed cotton plants is asserted to explain their lower sensitivity to salinity.
- Intervention effect Nitrate-fed seedlings had greater root length, root surface area and root volume than ammonium-fed seedlings, with or without salinity.
- Intervention effect Nitrate-fed seedlings had greater root viability than ammonium-fed seedlings, with or without salinity.
- Intervention effect Under salinity, seedlings treated with NO3-N had lower Na+ content than those treated with NH4-N.
- Mechanism Higher root Na+ efflux is asserted to explain the lower Na+ content of NO3-N-treated cotton seedlings.
- Intervention effect Net NO3− efflux from roots of nitrate-fed plants was lower than net NH4+ efflux from roots of ammonium-fed plants.
- Intervention effect Nitrate-fed plants under salinity accumulated much more nitrogen in tissues, especially leaves.
- Intervention effect Nitrogen accumulation in nitrate-fed plants is asserted to enhance photosynthesis under salinity.
