Onion (Allium cepa L.) thiosulfinates respond to increasing sulfur fertility

摘要: Onions (Allium cepa L.) were greenhouse grown with various sulfur fertilities and assayed for changes in thiosulfinates related compounds. The concentrations of methyl, n-propyl, 1-propenyl thiosulfinates, the zwiebelanes, onion lachrymatory factor (LF) increased a linear trend as fertility exception methanesulfinothioic acid S-n-propyl ester (MeS(O)SPr-n) S-methyl (MeS(O)SMe). (thiosulfinate plus zwiebelanes):LF ratio fertility, suggesting that former being formed at greater rate higher
