O Comprimento de Onda tem intima relação com a produção de GFP...........Green Fluorescent Protein.............
http://www.int-res.com/articles/meps_oa/m364p097.pdfAmong the known FPs and CPs, only the absorption
properties of CFPs spectrally match the major absorption
band of chlorophyll a and c at ~430 nm, making
them suitable for effective shielding of the photosynthetic
system of the zooxanthellae. Our results have
shown that the amounts of these proteins in coral tissue
increased at light intensities >80 μmol m–2 s–1 and saturated
at ~400 μmol m–2 s–1. This response is in striking
agreement with photosynthesis-irradiance curves of
zooxanthellae from different coral species that show a
similar increase and saturation at 400 μmol m–2 s–1
(Falkowski et al. 1990, Smith et al. 2005). However, the
detrimental effects of excessive light levels become apparent
once photosynthesis is saturated and the generation
of reactive oxygen species (ROS) increases (Smith
et al. 2005, Lesser 2006).
Esse LED tá nessa especificação de Comprimento de Onda........
Ultra Blue 430nm
http://ledmuseum.candlepower.us/led/ledblu1.htmO Royal Blue da Cree........tem 450nm............segundo o Data Sheet............
http://www.ledsupply.com/docs/cree-xre.pdfE agora esses aí........de 430nm............são bem interessantes................
Como se vê.............a leitura de PAR...................ou seja a medida..........da Intensidade do Fluxo Luminoso............também é Fator relevante...................na formação da GFP...................
