THE RESPIRATORY QUOTIENT OF SEEDLINGS OF LUPINUS ALBUS DURING THE EARLY STAGES OF GERMINATION.

In germinating seedlings of Lupinus albus, the initial respiratory quotient was found to be unity. After a drop to 0.76 at 9 hours, the value rose to 0.90 at 12 hours, and then fell to 0.64 at 60 hours. It is improbable that the fat oxidation system is the first to become activated.
