摘要：

The effect of solar radiation on the quercetin and kaempferol contents in the inflorescence of three broccoli cultivars ('Lord', 'Marathon' and 'Fiesta') was investigated from 1999 to 2001. Great differences in the contents of both flavonols, dependent on growing time and cultivar, were found. Quercetin and kaempferol contents varied from 14.3 to 81.0 mg kg(-1) f.w. and from 35.9 to 213 mg kg(-1) f.w., respectively. Inflorescences of the cultivar 'Lord' were characterised by the highest mean content of quercetin and those of cultivar 'Fiesta' of kaempferol. The contents of both flavonols were highly positively correlated with total solar radiation in the period from planting to the harvest of broccoli inflorescences. (c) 2005 Elsevier Ltd.
