Fig. 1. Ethylene production by GS apples stored under different treatments. Ethylene
wasmeasured every day from continuous airflow fromdesiccators containing apples
using gas chromatography. The detectable ethylene produced for the first day after
storage was taken as day for ethylene production in different treatments. Average of
three readings was taken as measure of ethylene for each set. Data are expressed as
means±SD of at least 3–4 replicates. ⁎⁎ and ⁎⁎⁎ significantly different from air at
P≤0.01 and 0.001, respectively, according to Student's unpaired t-test.
