STROMATINIA CEPIVORA Meaning and
Definition
-
Stromatinia cepivora is a term used in the field of plant pathology to describe a particular species of fungi that is known to cause diseases in various members of the onion family, including onions, garlic, and leeks. The fungus belongs to the Ascomycota division and is part of the family Sclerotiniaceae.
Stromatinia cepivora is characterized by its ability to infect and thrive in the internal tissues of these economically important plants, leading to the development of a disease commonly known as white rot. The fungus enters the plant through wounds or natural openings and starts its destructive process by producing enzymes that break down plant cell walls. This leads to the browning and eventual decay of affected plant tissues, resulting in the appearance of white, cotton-like mycelium on the surface of bulbs or stalks.
The spread of Stromatinia cepivora is facilitated by its ability to produce sclerotia, which are hard, survival structures that can remain viable for many years in the soil or in infected plant debris. These sclerotia serve as a source of infection for new plantings, particularly in conditions of high humidity and moderate temperatures.
Effective management of Stromatinia cepivora involves implementing cultural practices such as crop rotation, avoiding planting infected material, and maintaining proper sanitation measures. Fungicides may also be used to control the disease, although their efficacy can diminish due to the ability of the fungus to develop resistance.
Understanding the biology and impact of Stromatinia cepivora is crucial for farmers and researchers to effectively mitigate the damage caused by this pathogen and ensure the sustainable production of onions and related crops.
Etymology of STROMATINIA CEPIVORA
The word "Stromatinia cepivora" is a combination of two different words: "Stromatinia" and "cepivora".
1. Stromatinia: The term "Stromatinia" comes from the genus name of a group of fungi belonging to the Ascomycota phylum. The genus name was first proposed by French mycologist René Maire in 1904. The exact origin or etymology of "Stromatinia" is not explicitly clear.
2. Cepivora: The term "cepivora" is derived from Latin roots. "Cepa" means "onion" in Latin, while "vora" comes from "vorare", which means "to devour" or "to eat" in Latin. Therefore, "cepivora" can be understood as "onion-eating" or "onion-devouring".
