Biochemical responses of Romanian Calendula officinalis L. under salinity stress

Abstract

Total flavonoids and polyphenols content, and pigment amount under salt stress were analyzed in Calendula officinal is L. seedlings after 24 days of treatment with different salt combination, including NaCl, CaCl2,and MgCl2.The content of photosynthetic pigments increased according to increasing salinity concentration. Total polyphenols content generally decreased under salt stress, while flavonoids biosynthesis significantly increased almost under all salt treatments.
