Abstract

When apple fruits were stored in high and varied temperatures in air (IV), EFE, ACC synthase, internal ethylene concentrationand ethylene production in flesh tissue increased rapidly in the first 1-2 months, and large quantities of ACC and MACC were accumulated. Low temperature (0-DEGREES-C) inhibited ethylene production, the accumulation of ACC and MACC, but EFE activity was higher, and the activity of ACC synthase was markedly promoted in the later period of storage. At low temperauter storage under controlled atmosphere (II, 0-DEGREES-C) markedly inhibited ethylene production, the accumulation of ACC and MACC and the activities of enzymes involved in ethylene biosynthesis. TDCA (VI) also markedly inhibited ethylene biosynthesis in apple fruits. It indicates that high CO sub(2) can inhibit ethylene biosynthesis, as same as low temperature.
