Abstract
The genus Agave originates from the American continent and grows in arid and semiarid places, being México the center of origin. Many species of the genus are a source of diverse products for human needs, such as food, medicines, fibers, and beverages, and a good source of biomass for the production of biofuels, among many others. These plants are gaining importance as climate change becomes more evident as heat is reaching temperatures above 40 °C worldwide and rains are scarce. Many species of the genus grow in places where other plant species do not survive under severe field conditions, due to their CAM pathway for fixing CO2 where gas exchange occurs at night when stomata are open, allowing them to avoid excess loss of water. Most of the important species and varieties are usually propagated by offshoots that develop from rhizomes around the mother plant and by bulbils that develop up in the inflorescence, which are produced by the plant mostly when there is a failure in the production of seeds.
Areas for commercial plantations are growing worldwide and therefore in the need of big amounts of healthy and good quality plantlets. Although many Agave species produce seeds, it takes longer for the plants to reach appropriate maturity and size for diverse purposes. Micropropagation techniques for the genus Agave offer the opportunity to produce relatively high amounts of plants year around in relatively small spaces in a laboratory. Here, a protocol for micropropagation that has proven good for several Agave species (including species from both subgenera) is presented in detail with two different kinds of explants to initiate the process: rescued zygotic embryos and small offshoots that grow around a mother plant.
