Abstract

Imbibition of pretreated velvetleaf (Abutilon theophrasti Medic.) seed was most rapid when the chalazal region was wetted, but submergence of the chalaza in water delayed seed germination. Respiratory measurements indicated that the seed coat did not inhibit gas exchange under our experimental conditions. Effects of 2,4-dinitrophenol on germination indicated that radicle emergence and radicle growth were distinct processes, and that radicle emergence was more sensitive to low concentrations of the uncoupler.
