BUD NECROSIS IN TULIPS, A MULTIFACTORIAL DISORDER

W.J. de Munk
Bud necrosis in tulip bulbs is a whimsically occurring disorder causing the plants to develop incompletely or not at all in consequence of a decay in the buds from which the central sprout emerges. The injurious process, starting in the stamens during the period of storage and transport before planting can spread in the whole flower and other organs such as the leaves, the stem, the disc and the inner bulbscales.

In a number of cultivars bud necrosis can be stimulated by temperature treatment and by limiting the ventilation when Fusarium infected bulbs are present. Packing such bulbs in boxes means accumulation of ethylene which causes morphological aberrations of the buds: the buds are not closed at their tips. The aberrant form of the bud is a pre-requisite for the penetration of mites into the buds, which cause a process of decay. The sensitivity to bud rot is not equal for all varieties.
