More about the Family of Orchidaceae

More about the Family of Orchidaceae

The study of the peculiar morphology of flowers of orchids, plants maintain relationships with insects, has also fueled the nineteenth century ideas of Charles Darwin and has in part helped to establish its theoretical model evolution.

Culture and marketing

Mainly of tropical origin, these plants have been on the part of wealthy amateurs at the time of the expansion of European colonial empires, especially a fad. For a better understanding of their ecology, symbiosis that binds to certain specific fungi (genus Rhizoctonia in particular) during embryo development, the development of suitable culture media, sterile, and the creation of hybrid horticultural less fragile, have democratized culture. The high genetic variability of orchids, the rich natural source of cash for this taxon, also lends an artificial hybridization: more than one hundred thousand horticultural hybrids have been created since the development of culture methods.

Few orchids are used in food. However, there is the genus Vanilla, which is the vanilla pod. Vanilla is grown in tropical regions, and its need for shade makes possible its use in agroforestry.

The fahami (Jumellea fragrans) into the making of rum, giving it a caramel flavor. The gathering takes place in nature, the sites of production and creates a rarefied phase of the plant.

The orchids of temperate and Mediterranean areas, tubers very suggestive, have inspired the followers of the theory of a possible aphrodisiac signatures: we now know it is not. But in regions of the Maghreb, these orchids are still dug in preparation for the popular salep. In particular, Turkey, 36 species from 10 genera are therefore threatened with extinction, and an estimated 42 the number of species have already disappeared over the last decade.
