摘要: Dark respiration in the light was estimated leaves of two woody species (Heteromeles arbutifolia Ait. and Lepechinia fragans Greene) using different approaches based on gas-exchange techniques: Kok method Laisk method. In all cases, dark lower (P < 0.05) than darkness, indicating that inhibited light. Rates by were 52% higher those Differences between methods could be explained low ambient CO2 concentrations required approach. The mean value inhibition for species, corrected concentration effect, 55%. Despite differences leaf characteristics values photocompensation point, at which rate photosynthetic uptake equaled photorespiratory evolution, very constant, suggesting an excellent consistency results obtained with
