Abstract:
At 25°C the activity of pectinmethylesterase (PME) solution incubated in ethylene atmosphere (100 μl/liter) was lower than that of PME solution incubated in air. On the other hand, at 6°C the activity of the ethylene-incubated PME was higher than that of the air-incubated solution. The effects of both temparature and ethylene on PME-solution activity are reversible phenomena. Ethylene accelerated both softening was accelerated as PME activity in avocado fruit at 25°C. However at 6°C softening was accelerated as PME activity was promoted by ehtylene treatment. Ethylene had similar effects on PME activity in both purified enzyme solution and in vivo systems. © 1974 Oxford University Press.
