Oker-Blom, P. Kellomiiki, S. and Smolander, H., 1983. Photosynthesis of a Scots pine shoot: the effect of shoot inclination on the photosynthetic response of a shoot subjected to direct radiation. Agric. Meteorol.,.
A set of photosynthetic responses of a Scots pine (Pinus sylvestris L.) shoot to light was derived from the shoot geometry and the photosynthetic response of a single needle. Computations showed that the shape of the photosynthesis light-curves varies substantially depending on the direction of radiation relative to the shoot position. Differences in the initial and maximum rates of photosynthesis were due to changes in the effective projection area and the irradiated fraction of the shoot, respectively.
