Abstract

This research aimed to study the effect of ultraviolet radiation on Beta vulgaris pigments. Seeds were exposed to UV radiation at different  distances  ( 5,10 and 15 cm) and exposure periods (0, 0.5, 1, 2 and 4 hours). Beta vulgaris has been regarded as the unique source of betalains. Red betacyanins and yellow betaxanthins are two categories of betalains, which are nitrogen-containing plant pigments. The results showed that UV radiation significantly affected the content of chlorophyll a, chlorophyll b, the ratio  of chl a/chl b, carotenoids, betacyanins, betaxanthins and total betalains depending on the distance and exposure period.
