Table 3. Effects of CO2 concentrations (EC, elevated; AC, ambient) and Kinetin (KN, treat; CN, control) on biomass allocation in Koshihikari and Takanari. 1Expressed on a 0% moisture content basis; 2CE: EC effect, (EC/AC-1) x 100; 3Unhusked grain yield divided by aboveground biomass both on a 0% moisture content basis; 4Kinetin effect: (KN/CN-1) x 100; 5Statistically significant effects are indicated ***, P < 0.001; **, P < 0.01; *, P < 0.05; The value indicates the probability between 0.05 and 0.1; ns, not significant.
