摘要
The biosynthesis of scoparone (6,7-dimethoxycoumarin) was associated with resistance of mature fruits of tangelo Nova, Citrus aurantium, and Citrus paradisi to infection by Phytophthora parasitica. Levels of scoparone 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 phytoalexin in fruits of these cultivars.
