A disengagement of the cyanide-resistant, alternative respiratory pathway in soybean (Glycine max (L.) Merr.) callus tissue was observed prior to the start of deoxyisoflavone production stimulated by addition of the cytokinin benzyladenine. To test whether this loss of alternativepathway activity
Peeling the abaxial epidermis from oat leaves (Avena sativa var. Victory) induces the formation of wound ethylene and the development of resistance to cellulolytic digestion of mesophyll cell walls. Ethylene release begins between 1 and 2 hours after peeling in the light or dark.
High irradiance and moderate heat inhibit the activity of the photosynthetic apparatus of oat (Avena sativa L.) leaves. The incubation of oat leaves under high light intensity in conjunction with high temperatures strongly decreased the maximal quantum yield of photosystem (PS) II, indicating the
