Enzymic and non-enzymic liberation of tulipalin A (α-methylene butyrolactone) in extracts of tulip
The present findings demonstrate that, in vitro, the precursor must be split chemically or enzymically to yield the fungitoxic tulipalin A.
DETECTION OF LILY SYMPTOMLESS VIRUS (LSV) IN BULB TISSUE OF LILY BY MEANS OF ELISA
Isolation and identification of α‐methylene‐butyrolactone, A fungitoxic substance from tulips
A fungitoxic substance has been isolated from extracts from the white skins of tulip bulbs, from the fleshy bulb scales and from the flower pistils. The compound was identified as…
A fungitoxic substance extracted from tulips and its possible role as a protectant against disease
It was concluded that the fungus is not able to penetrate into the tulip bulb during the greater part of the growing season, and a protecting barrier was demonstrated to be present in the white skin.
ENZYMATIC LIBERATION OF TULIPALIN (Î±-METHYLENEBUTYROL-ACTONE), A FUNGITOXIC SUBSTANCE ISOLATED FROM TULIPS

A method for determining the concentration of the fungitoxic lactones tulipalin A and B in crude extracts of various parts of the tulip is described. After a simple fractionation of the extracts on…
A POSSIBLE EXPLANATION OF VARIATIONS IN SUSCEPTIBILITY OF TULIP BULBS TO INFECTION BY FUSARIUM OXYSPORUM
Application of enzymes during bulb tissue extraction for detection of lily symptomless virus by ELISA in Lilium spp
Lily symptomless virus (LSV) was readily detected with the enzyme-linked immunosorbent assay (ELISA) in leaves ofLilium Mid-Century hybrids cvs Enchantment and Destiny andLilium speciosum cv.…
In vitro study on the benomyl tolerance of Fusarium oxysporum f. sp. tulipae
Isolates of Fusarium oxysporum f. sp. tulipae were tested for tolerance to benomyl. Although all isolates were relatively insensitive to benomyl, no tolerance was found. Some isolates, however,…
