Fasciation (or cresting) is a condition of plant growth in which the apical meristem, normally concentrated around a single point, producing approximately cylindrical tissue, becomes elongated perpendicularly to the direction of growth, producing flattened, ribbon-like, crested, or elaborately contorted tissue. The phenomenon may occur in the stem, root, fruit, or flower head. Fasciation can be caused by a mutation in the meristematic cells, bacterial infection, mite or insect attack, or chemical or mechanical damage. Some plants may inherit the trait. Fasciation is rare overall, but has been observed in at least a hundred different plant species.
None. The condition is unlikely to spread, but depending on where on the plant it is it may or may not affect yield. Retain or destroy affected plants as required.
