||P.88 left column top paragraph: "As mentioned before, the Chl
fluorescence rise of the OJIP test reflects the kinetics and heterogeneity
involved in the reduction of the plastoquinone pool, QA. Among the
parameters, M0 expresses the net closing rate of RCs [reaction centers] during illumination. As shown in the Table 3, M0 increased as N limitation degree increased, suggesting that the rate of RCs closure increased due to N
limitation, i.e. electron transport chain (ETC) was faster reduced under
N limitation. However, since M0 is also expressed as M0=TRo/RC − ETo/RC, and given that ETo/RC (electron transport beyond QA) didn't change significantly between the different degrees of N limitation (Table 3), it could be concluded that the closure rate of the RCs was increased due to the increase of trapping flux per RC (TRo/RC)." See table 1 beneath table 3 for definition of terms.
