Light interception by isolated plants

摘要: Abstract Foliage of single plants invariably appears to be nonuniformly distributed when viewed from the direction sun. The nonuniformity foliage in space and its constraint within an envelope should both considered analyzing light interception. This study uses a generalized treatment distribution projection onto plane or below canopy. Given this projected distribution, general penetration law Mann et al. (1977) can applied calculate either interception penetration. analysis is illustrated by calculation sunlight model shape ellipsoids. Different distributions density with height radial distance give different interceptions. Comparison interceptions uniform nonuniform structures show differences as high 43%.
