Phenols and Flavonoids in Carthamus Tinctorius L. Cultivars Under Pathogenesis of Alternaria Carthami

The present study was carried out to determine the accumulation of phenol and flavonoids in four safflower cultivars infected by Alternaria carthami. Phenol content decreased in infected leaves of cultivars Nari-38 and Nari-6 as compared to that in healthy leaves while it significantly increased in the infected leaves of Nari-H-23 and Nari-NH-1 as compared to healthy leaves. Flavonoids slightly increased in all cultivars under the influence of the disease. The findings revealed that Nari-H-23 was more resistant as compared to other cultivars against Alternaria carthami.
