Notes:
Summary Sugar accumulation occurred in senescent tubers at 20°C even in the absence of wilting and particularly if sprout growth was prevented chemically or the sprouts removed. Without sprout growth the considerable sweetening was not accompanied by greatly increased respiration, as occurred in sprouting tubers. Senescent sweetened tubers without sprouts had a variable respiratory quotient, tending on average to be rather high, but this could have resulted from the damage caused by desprouting or chemical suppression. A high (c. 1.3–1.4) respiratory quotient in undamaged sweetened tubers cannot be excluded, however, as it could be masked by the high respiration of the sprouts with a presumed quotient of 1.0. Handling led to variable respiratory quotients, an effect which could last for several weeks.
