PHYSIOLOGICAL AND BIOCHEMICAL STUDIES IN PLANT METABOLISM: I. THE RESPIRATION OF THE SEEDLING WHEAT LEAF IN STARVATION AND ONTOGENY
1949
Uniform conditions for the culture of the plants and for conducting starvation–respiration experiments upon the first seedling leaves permit the recapture and hence thorough investigation, of transitory physiological states. A standard sample of isolated, mature leaves, so produced and starved, is shown to be heterogeneous when tested by the tempo at which the tissues in different parts of the sample pass through the color changes that accompany starvation. These are correlated with respiration. Interleaf variation in tempo is relatively small. Intraleaf variation is maximal and the leaf is polarized at isolation but a complex redistribution of tempo within each leaf brings about depolarization and diminishes intraleaf heterogeneity as starvation progresses. The respiration of such a starving sample follows a time course of characteristic pattern, all the prominent features of which have their homologues in the corresponding patterns of younger and older leaves. The homologous characters undergo gradual m...
