ERIG, Alan Cristiano  and  SCHUCH, Márcia Wulff. Photoautotrophic micropropagation and use of the natural light. Cienc. Rural [online]. 2005, vol.35, n.4, pp.961-965. ISSN 1678-4596.

In spite of the micropropagation to be diffused thoroughly and to present advantages in relation to the traditional methods of propagation, its use in commercial scale in the scions production is limited, mainly, due to the high cost for scions obtaintion. The development of photoautotrophic micropropagation systems with the use of natural light appears as potential possibilities of increasing the efficiency of the micropropagation and help in the cost reduction, making it possible commercially. However, the photoautotrophic micropropagation and the use of natural light lack studies. In Brazil, researches with the intention of the use of the natural light in the photoautotrophic micropropagation are practically inexistent, in spite of there bring strong reasons for its research and implementation, mainly, for the fact of Brazil being a country of tropical and subtropical climate, with great readiness of natural light along the year, and being in need of new technologies for the scions production section. This review seeks to discuss aspects related to the photoautotrophic micropropagation and the use of natural light, as possibilities making turn the micropropagation a method of scions production viable commercially.
