Effects of Near Ultraviolet and Green Radiations on Plant Growth

Abstract
Selective removal of near-UV and green wavelenghts from white light permitted enhanced growth of marigold, tomato, corn, and Impatiens plants, Chlamydomonas cells, and the mycelium of Sordaria. Addltons of near-UV and green radiations caused repressions in the growth of marigold and Sordaria. These wavelengths did not alter the oxidative mechanisms of mitochondria, intact algal cells, or marigold leaf tissues. The capacity for chlorophyll and carotenoid synthesis of Euglena cells was unaffected by these wavelengths.
