Abstract

BOOTH1 has recently directed attention to the various mechanisms which are responsible for carotenoid destruction in green tissues, two of which, a photochemical reaction and an enzymic reaction, have been examined in alfalfa leaf macerates2. Enzymic destruction of β-carotene is reported to be greatest in plant tissues containing chlorophyll1, and we have therefore made a preliminary examination of the destruction of endogenous carotenoids in isolated chloroplast suspensions prepared from leaves of spinach beet.
