micropropagação

Micropropagation, also known as plant tissue culture, is a technique used to produce a large number of progeny plants, using various techniques of plant tissue culture. The method involves the asexual propagation of a parent plant in a sterile laboratory environment. This allows for the rapid multiplication of desirable plant varieties, even those that are difficult to propagate by conventional means. The process typically begins with a small piece of plant tissue, called an explant, which is surface sterilized and then placed on a nutrient-rich growth medium. This medium contains hormones that encourage cell division and differentiation, leading to the development of shoots and roots. Once plantlets have formed, they are transferred to a different medium for further development and then acclimatized to ex vitro conditions before being planted in soil. Micropropagation is widely used in commercial horticulture and agriculture for mass production of plants, especially for species that are slow to propagate sexually or have specific desirable traits like disease resistance or high yield. It is also a valuable tool for plant conservation, allowing for the propagation of endangered or rare species. Furthermore, it facilitates the production of disease-free plants, which is crucial for preventing the spread of pathogens in agricultural settings. The technique offers precise control over the growing environment, ensuring consistent quality and rapid propagation.
