Abstract
Terashima, I. 1986. Dorsiventrality in photosynthetic light response curves of a leaf.—J. cxp. Bot. 37 399–405 The photosynthetic light response curve of a leaf of Glycine max (L.) Merrill obtained by illuminating the adaxial side lay above that obtained by illuminating the abaxial side. However, after inverting the leaf for 11 d, the curve obtained by illuminating the abax.ial side came to lie slightly above that obtained by illuminating the adaxial side. The difference in the shape of light response curves is satisfactorily explained only when the intra-leaf heterogeneities in light absorption and in photosynthetic activity are taken into account.
