The production by species of Allium of alkyl sulphides and their effect on germination of sclerotia of Sclerotium cepivorum Berk

摘要: A number of n-propyl and allyl sulphides were shown to stimulate germination sclerotia Sclerotium cepivorum in soil. Several these evolved by chopped garlic cloves onion bulbs, their extracts, as well distillates condensates prepared from extracts. Sulphides produced methyl compounds, whereas those derivatives. Few or no volatile detected gas chromatography head spaces intact Allium plants although it is considered that small quantities may be The stimulatory activity appears entirely due alkyl sulphide content extracts at least partially so.
