Cotton

Description

Cotton is made up of 4 different species that can be classified into 3 different groups. There are American cotton (Gossandpium hirsutum L.), Egyptian cotton (Gossandpium barbadense L.) and Indian cotton (Gossandpium arboreum L. and Gossandpium herbaceum L.). The most widespread species is American cotton. This one has a deep and taproot. It has an erect stem with vegetative branches that have a continuous growth. From a certain point on the main stem, fruitful branches are generated which have flower buds. These flower buds with white or cream colored petals are what will end up producing the cotton fibers. The flowers are self-fertile, although they can be pollinated by external agents.

In Spain the cotton crop is not very widespread, but it occupies approximately 65,000 hectares. Its cotton production (raw) is 212,000 tons per year.
