A possible explanation of variations in susceptibility of tulip bulbs to infection by Fusarium oxysporum

, : A possible explanation of variations in susceptibility of tulip bulbs to infection by Fusarium oxysporum. Acta Horticulturae [Technical Communications of the International Society for Horticultural Science] 2: 225-229

Some evidence was obtained that variations in susceptibility to F. oxysporum f.sp. tulipae at different growth stages were related to the conc. of the fungitoxic compound tulipalin ( alpha - methylene butyrolactone) in the outermost bulb scales.
