Linkage Between Output of Electric Energy by Polar Tissues and Cell Oxidation

Freezing Stresses and Survival

“…Several proposals involve mechanisms at membranes (51,66,112,117,123,128,160). Pumping mechanisms are not well defined and may not be primarily involved in freezing injury (78) .…”

RELATION BETWEEN LIGHT AND THE ELECTRIC POLARITY OF CHARA

“…In The electric polarity of each plant was determined at intervals of two hours or more for 48 hours or longer and it was found that in the unstimulated condition the apex remained positive. There were a few exceptions to this rule as the apex became negative without obvious external stimulation during the first 24 hours. This was a temporary condition since in 6 to 12 hours the apex again became positive and remained so to the end of the experiment.…”

Polar Distribution of Respiratory Rate in the Onion Root Tip

“…These factors were given as evidence in support of the theory of the origin of bioelectric potentials as oxidative-reductive systems in flux equilibrium. MARSH (9) showed that the electrical potential difference between apical and basal contacts on the root could be depressed by KCN, and ROSENE and LUND (11) found that the displacement of oxygen with hydrogen around the root also lowered the E.M.F. The readmission of oxygen gave a "rebound" effect in the p.d.…”
