Paper Abstract

Dennis St. George John Feddes (Dept. of Agricultural Engineering University of Alberta Edmonton AB Canada T6G 2Hl) A prototype light collection and transmission device was developed and evaluated for the potential of irradiating plants grown in an opague growth chamber. Results indicated that the device transmitted light with a photon flux of 130 1amol/s/m2 (4000-7000 nm) to the bottom of the growth chamber when direct solar radiation was 800 W/m2 (300-2500 nm) outside. The overall collection and transmission efficiency for photosynthetically active radiation is 19. 2. A growth trial with plants indicated that artificial lighting is required during cloudy periods. 1.
