How do orchids evolve?
After the biological extinction, there was widespread destruction of ecological systems. However, orchids rapidly diverged and evolved into five subfamilies through gene family expansions and contractions, producing high diversity and adapting rapidly to the new ecosystems.
Which technique is used to grow orchids?
The six main techniques used for orchid propagation are division, backbulbs, serial cuttings, kiekies, micro-propagation and seed culture. Conventionally, sympodial orchids like Cattleya, Dendrobium, Paphiopedilum and Cymbidium are multiplied through divisions whereas monopodials viz.
How do orchids grow from seed?
Propagation. Propagating orchids from seed is quite difficult. Unlike the seeds of other plants, orchid seeds do not contain nutritional storage tissues.

Do orchids produce seeds?
Their dependence on certain fungal partners is most probably the reason why orchids produce vast numbers of tiny seeds. With their small size, low weight and balloon-testa, orchid seeds are perfectly adapted to wind-dispersal. However, their strategy is not to travel long distances.
How do you grow monkey orchid seeds?
