Abstract
Patterns of gas exchange and protein synthesis were measured in developing leaves of clonal Populus x euramericana plants. Net photosynthesis and apparent photorespiration (Warburg effect) were zero in very young leaves, but then increased to maximum levels in recently mature leaves. Both processes declined in old leaves, but the decline in photosynthesis was more rapid. Mitochrondrial (dark) respiration decreased with leaf age and was less in the light than in the dark, except in very old leaves, where it increased sharply in the light. Diffusion resistance and CO2 compensation concentration declined to minimum levels in recently mature leaves; however, resistances increased markedly in older leaves, whereas CO2 compensation remained at a minimum. Soluble protein concentrations and incorporation of 14C-photosynthate into protein declined throughout leaf development. Protein turnover was slight in expanding leaves, but was substantial after leaves matured. Expanding leaves synthesized predominantly Fraction I protein, but formation of this protein was slight once leaves matured. The significance of these findings in relation to the developmental pattern of net photosynthesis in poplar leaves is discussed.
