 An Erratum on Nitrogen Supply Affects Yield and Grain Filling of Maize by Regulating Starch Metabolizing Enzyme Activities and Endogenous Hormone Contents by Yue, K., Li, L., Xie, J., Liu, Y., Xie, J., Anwar, S., and Fudjoe, S.

Due to a production error, the minus sign (–) between “maximal grain” and “filling rate” (equation 2) should be a hyphen (-).

A correction has been made to the section “Measurements and Calculations for Grain Filling, Enzymes, and Endogenous Hormones Measurements,” subsection “Grain-Filling Traits,” Equation 2:

“Time for maximal grain-filling rate (Tmax) = lnB/C”

Due to a production error, the minus sign (–) between “weight increment” and “achieving maximum” (in equation 3) should be deleted; additionally the minus sign (–) between “Maximum grain” and “filling rate” (equation 2) should be a hyphen (-).

A correction has been made to the section “Measurements and Calculations for Grain Filling, Enzymes, and Endogenous Hormones Measurements,” subsection “Grain-Filling Traits,” Equation 3:

“Grain weight increment achieving maximum grain-filling rate (Wmax) = A/2”

Due to a production error, the minus sign (–) between “maximum grain” and “filling rate” (equation 4) should be a hyphen (-).

A correction has been made to the section “Measurements and Calculations for Grain Filling, Enzymes, and Endogenous Hormones Measurements,” subsection “Grain-Filling Traits,” Equation 4:

“Maximum grain-filling rate (Gmax)”

Due to a production error the minus sign (–) between “Active grain” and “filling period” (in equation 5) should be deleted.

A correction has been made to the section “Measurements and Calculations for Grain Filling, Enzymes, and Endogenous Hormones Measurements,” subsection “Grain-Filling Traits,” Equation 5:

“Active grain-filling period (AGP) = 6/C”

Due to a production error the minus sign (–) between “Average grain” and “filling rate” (in equation 6) should be deleted.

A correction has been made to the section “Measurements and Calculations for Grain Filling, Enzymes, and Endogenous Hormones Measurements,” subsection “Grain-Filling Traits,” Equation 6:

“Average grain-filling rate (Gmax) = W/56”
