Other claims from this paper (14)
- Intervention effect Cd stress significantly reduced grain yield, panicle number, and spikelets per panicle in rice.
- Intervention effect Cd stress significantly reduced filled spikelet rate, grain weight and shoot dry weight in rice.
- Association Genotypes with higher Cd-tolerance showed smaller growth inhibition under Cd stress than genotypes with lower Cd-tolerance.
- Method / resource Cd-tolerance is consistent across growth stages, so it can be evaluated at early seedling growth in rice.
- Association Cd concentration in rice shoots and grains decreased as growth progressed.
- Association Cd accumulation in rice increased as growth progressed.
- Intervention effect Cd stress reduced grain K, P and Mg concentration in rice.
- Intervention effect Cd stress reduced grain Mn and Zn concentration in rice.
- Intervention effect Cd stress increased grain Fe, Cu and Ca concentration in rice.
- Intervention effect Cd stress inhibited synthesis of S-containing amino acids such as glutamic acid and cysteine in rice grains.
- Association The Cd-induced inhibition of amino acid synthesis was more severe in Cd-sensitive rice genotypes than in Cd-tolerant ones.
- Association Cd-tolerant rice genotypes had higher glutamic acid and cysteine concentration in grains than sensitive ones in all treatments.
- Observation The effect of Cd stress on free amino acid concentration in rice grains varied among amino acids and genotypes.
- Mechanism Metabolism of these amino acids may be associated with the Cd tolerance response of rice genotypes.
