e fresas in vitro CULTIVOS CELULARES VEGETALES IN VITRO (FRESA)

Cultivos In vitro.
El cultivo en un medio nutritivo, en condiciones estériles, de plantas, semillas, órganos, explantas, tejidos, células y protoplastos de plantas superior, se caracterizan porque ocurren a microescala, sobre todo en una superficie pequeña; se optimizan las condiciones ambientales, en lo que se refiere a factores físicos, nutricionales y hormonales, se excluyen todos los microrganismos (hongos, bacterias y virus), así como también las plagas de las plantas. 1. La multiplicación in vitro es masiva y más rápida. 2. A veces es posible propagar especies in vitro, que no pueden ser multiplicadas en forma tradicional. 3. El crecimiento de las …ver más…

PLANT CELL CULTURES IN VITRO (STRAWBERRY)

In vitro cultures.
The culture in a nutrient medium under sterile conditions, plants, seeds, organs, explants, tissues, cells and protoplasts of higher plants, are characterized because occur to microescala, especially in a small area; environmental conditions are optimized, in respect to physical, nutritional and hormonal, are excludes all microorganisms (fungi, bacteria and viruses), as well as plant pests.
Advantages:
1. Multiplication in vitro is more massive and quick. 2. Sometimes it is possible to propagate in vitro species that can not be multiplied in a traditional manner. 3. The growth of in vitro propagated plants are more vigorous than those cloned in vivo. 4. Multiplication is achieved disease free. 5. Homogeneity of the material. 6. Multiplication round. 7. Space saving. 8. Conservation of genetic material. 9. Easy transport.
Disadvantages:
1. In some systems, in vitro propagation is weak genetic stability. 2. There may be excessive production of lateral branches. 3. The acclimation of plants is a difficult process. 4. Difficult initial response of some species and genotypes.
Methods of vegetative propagation in vitro: 1. Cuttings from nodal segments. 2. Method axillary buds. 3. Regeneration of explants.
