Abstract

ZAZUETA TORRES, Norma Delia et al. In vitro growth of Sclerotium rolfsii in response to the light quality of three types of fluorescent lamps. Rev. Mex. Cienc. Agríc [online]. 2021, vol.12, n.1, pp.141-147.  Epub Feb 21, 2022. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v12i1.2313.

The investigation was carried out to know the influence of the quality of light on the radial growth of the mycelium, production of sclerotia and mycelium biomass of Sclerotium rolfsii cultivated in vitro. The treatments consisted of cold, neutral and warm white light, emitted by fluorescent lamps, with a photosynthetic photon flux density (400 to 700 nm) of ≈300 μmol m-2 s-1, which were established under a completely randomly with 10 repetitions. The light spectrum emitted by fluorescent lamps influenced the growth of the fungus in vitro. Cold white light caused a reduction in radial growth, biomass and sclerotium production of Sclerotium rolfsii due to the higher spectral content of blue light (400-500 nm).

Keywords : Sclerotium rolfsii; biomass; light spectrum; mycelium; sclerotia.
