Table I. Respiration (TTC-H), energy content (NADH + NADPH), and energy use efficiency (EE) of hypocotyl explants

Three repetitions per assay and 35 plants per repetition were used. Values shown are percentages versus control. EUE line data were as published by Hauben et al. (2009). Significance was determined by ANOVA with Dunnett’s posttest: *, P < 0.05; **, P < 0.01; ***, and P < 0.001; TTC-H, reduced 2,3,5-triphenyltetrazolium chloride; ND, not determined.
