Publication date: Available online 31 October 2018Source: Journal of Photochemistry and Photobiology B: BiologyAuthor(s): G. Gurrea-Ysasi, V. Blanca-Gimenez, I.C. Fita, A. Fita, J. Prohens, A. Rodriguez-BurruezoAbstractSpectral Solar Photosynthetically Photon Flux Density (PPFD) (380 to 780 nm) reaching the surface of a plant in different lighting conditions has been analyzed in order to better understand the different photosynthetic performance of plants depending on their spatial situation and the vegetation surrounding.A comparison between the shadow of several trees in a sunny day and the case of a cloudy day in an open space has been studied. Three isolated trees (a palm tree, an olive tree and a shrub oleander) and a tipuana grove have been studied.The study has been developed in V...
