TEMPERATURE CHARACTERISTICS FOR THE OXYGEN CONSUMPTION OF GERMINATING SEEDS OF LUPINUS ALBUS AND ZEA MAYS.
The rate of oxygen consumption by germinating seeds of Lupinus albus and of Zea mays was studied as a function of temperature (7-26 degrees C.). The Warburg manometer technique was used, with slight modifications. Above and below a critical temperature at 19.5 degrees C. the temperature characteristic for oxygen consumption by Lupinus albus was found to be micro = 11,700+/- and 16,600 respectively. The same critical temperature was encountered in the case of Zea mays, with temperature characteristics micro = 13,100+/- above and micro = 21,050 below that temperature.
