Other claims from this paper (12)
- Intervention effect Under normal water, a moderate decrease in the ammonium/nitrate ratio to 50:50 increased nitrate content in rice leaves and roots.
- Intervention effect Under normal water, the 50:50 ammonium/nitrate ratio did not affect net photosynthetic rate in rice.
- Intervention effect When nitrate N exceeded 50% of the N supply, physiological and metabolic indexes in rice decreased significantly.
- Intervention effect When nitrate N exceeded 50% of the N supply, growth of rice seedlings was inhibited.
- Intervention effect Under moderate water stress, the 50:50 ratio increased net photosynthetic rate of the top three rice leaves compared with normal water and 100% ammonium N.
- Intervention effect Under moderate water stress, the 50:50 ratio promoted accumulation of compatible osmolytes in rice compared with normal water and 100% ammonium N.
- Intervention effect Under moderate water stress, the 50:50 ratio improved nitrogen uptake in rice compared with normal water and 100% ammonium N.
- Intervention effect Under moderate water stress, the 50:50 ratio boosted growth of rice seedlings compared with normal water and 100% ammonium N.
- Association Under moderate water stress, rice genotypes differed significantly in their responses to increasing nitrate N.
- Association Indica rice was superior to japonica rice in net photosynthetic rate and nitrogen use efficiency.
- Association Hybrid indica rice was superior to inbred indica rice in net photosynthetic rate and nitrogen use efficiency.
- Association Japonica upland rice was better than japonica paddy rice in net photosynthetic rate and nitrogen use efficiency.
