Abstract
The effect of ethylene and ethephon treatments on nootkatone accumulat ion in the rind of grapefruit was investigated. Considerable increases in the levels of this sesquiterpene were observed in the picked and u npicked grapefruits treated. The changes induced in the maturation-sen escence stage of grapefruit by these treatments consisted of an accele rated carotenogenesis process in the rind, along with morphological ch anges in the exocarp and ultrastructural changes in the plastids. Thes e results suggest that ethylene regulates nootkatone biosynthesis by a ccelerating the maturation-senescence processes in grapefruit rind,
