The meaning of electrophoretical analyses of protein of vegetable tissues in the study of vegetable physiology is considered to be very important, and we prescribed the conditions of its electrophoresis at first.That is, we proposed newly the mixed buffer of K-phosphate and Na-borate, and fixed in details the conditions of electrophoresis concerning this buffer.Then under the fixed conditions of electroporesis, we sought the interrelation between the electrophoretic protein of vegetable tissues and the physiological phenomena.The more vigorous the functions of leaves or seeds, the more complex the electrophoretical patterns of the extracts of these tissues.Thus, the existence of close interrelation between physiological phenomena and electropholetic protein was shown, and, moreover, the dynamic character of electrophoretic protein was inferred by the results of autolysis.
