Abstract
The biosynthesis of scoparone (6,7-dimethoxycoumarin) was associated w ith resistance of mature fruits of tangelo Nova, Citrus aurantium, and Citrus paradisi to infection by Phytophthora parasitica. Levels of sc oparone increased by treating fruit with Brotomax, which also enhanced the resistance of fruit to the fungus. Lesion development was reduced by as much as 40%. Scoparone is therefore proposed as a possible phyt oalexin in fruits of these cultivars.
