Effects of Pod Removal on Metabolism and Senescence of Nodulating and Nonnodulating Soybean Isolines

Abstract
The objectives of this work were to determine the effect of sink strength (presence or absence of pods) and nitrogen source (nodulating versus nonnodulating plants) on enzymic activities, chlorophyll concentration, and senescence of soybean (Glycine max [L.] Merr. cv Harosoy) isolines. A 2-year (1981-1982) field study was conducted.
