Abstract Leaves of Lotus scoparius Nutt., a Mediterranean-climate shrub, exhibited higher photosynthetic capacities when grown under winter (10/14 h, day/night) than summer (14/10 h) photo-periods, even though total daily photon irradiance was higher under summer photoperiods. Photosynthetic dependence on natural variations in photo-period, such that activity was higher under photo-periods associated with expected precipitation, may be a more dependable environmental parameter than total irradiance in temperate habitats with winter-spring precipitation patterns and where seasonal cloudiness may cause total daily irradiance levels to be highly variable.
