Plant fasciation is one of the mysteries of the garden, but be a smart gardener and remove the odd growth. But what causes fasciation? This physiological disorder, called fasciation, can occur in almost any plant part, but is most noticeable in the stems or inflorescences.
It could be a random genetic mutation. In recent visits to watermelon fields in Delaware for pollination and fruit set surveys, we found a high number of pollenizer plants in one field that had one or more fasciated stems. And, just because a particular plant exhibited fasciation one season, that does not necessarily mean it will again in the future. The growing tip or apical meristem of the plant, which normally produces cylindrical tissue, instead becomes elongated perpendicularly to the direction of the growth or it splays out to the sides.
Consider it a plant mistake. The stem end submitted was flattened, ribbed and coiled.
Mammillaria geminispina Cristata L and M. April 27, 2007 - Author: It occurs as a mutation in a single cell that divides and creates other cells in the next zone of development.
Euphorbia sp.: Bulk buying at the Southeast Area Farmers' Market provides benefits for low-income families. The plant could be a woody ornamental like a tree or shrub, or a perennial or annual plant, but it is obvious the growth is far from normal.
Although the causes of fasciation are not well understood, it is most likely because of a hormonal imbalance.
Log in Search the site: With any kind of strange growth, the first thing to do is eliminate the possibility that the odd leaves or stems were caused by a light dose of weed killer or herbicide. We occasionally have plants submitted to the lab with a weird plant deformity known as fasciation. The phytoplasmas represent an evolutionary midpoint between cellular pathogens such as bacteria and non-cellular viruses. Phytoplasmas lack a protective cell wall but have a cell membrane. Lots of things can cause the mutation to occur.
If nothing else, fasciation is fascinating. Common examples include cockscomb upper left , fantail willow upper right , crested hens-and-chicks and the fasciated candelabra cactus.
