摘要: Nitrogen-efficient and nitrogen-inefficient wheat genotypes were identified on the basis of differential response 16 with low (1 mM) high (25 nitrogen (N) supply. Growth performance, measured in terms fresh weight, dry weight length root shoot, was higher N-efficient than N-inefficient at N levels. Interestingly, although growth did not show any change increasing level supply, there a marked increase level. To work out this to levels, we investigated nitrate uptake rate activities assimilatory enzymes leaves genotypes. Nitrate kinetics these revealed that mediated by high-affinity transporter systems, whereas those N-ineff...
