Summary

Using a gas adsorbent to condense volatiles produced by carrot, soyabean and sunflower seeds sealed in plastic bottles, 11 compounds produced by carrots, 2 produced by soyabeans and 2 produced by sunflowers were identified. Ethanol was the only compound produced by all seeds. Analysing 63 cultivars from 47 species, methanol, ethanol, acetone and acetaldehyde were the most common volatile compounds. Two tropical species, Cleome spinosa and Cyperus alternifolius produced large amounts of butane. No volatiles were detected from rice or barley seeds stored at -10 deg C, but heating at 80 deg C for 20 min caused emission of some compounds, suggesting that volatiles were trapped within the seeds at subzero temperatures. The amount of volatiles evolved increased with increasing period or temperature of storage, suggesting that the compounds were produced metabolically even in dry seeds.
