BORTOLOTTI DA SILVA, Adriano et al. Natural light in pineapple (Ananas comosus L) micropropagation. INCI [online]. 2008, vol.33, n.11, pp.839-843. ISSN 0378-1844.

Shoot tips of Ananas comosus ‘Imperial’ were rooted in vitro under two environments (artificial and natural light) and after two months the plantlets were transferred to commercial substrate (Plantmax^®) in a greenhouse. Plant growth and leaf anatomy were evaluated at 0, 7, 15, 30 and 60-days during acclimatization. The in vitro rooting under natural light provides better agronomic and anatomical performances of Ananas comosus plants, with the benefit of saving electric energy for artificial illumination in vegetal tissue culture laboratories.
