Morphogenèse foliaire et activité photosynthétique chez le soja (Glycine max)

The main stem development and the photosynthetic activity of leaves 2 to 9 were studied in soja (Glycine max (L.) Merr.) at the leaf blade extension and adult stages. A correlation between the different leaf growth parameters (rates, durations) and the phyllochrone has been demonstrated. That correlation varied with the age and rank of the leaf. Moreover, the existence of correlations between net photosynthesis on one hand and the rate of development and the leaf growth kinetics on the other hand reveals an interdependence between photosynthesis and morphogenesis.
