Chlorophylls and carotenoids in calli of sugar beet genotypes

Abstract

Chlorophyll (Ch1) and carotenoid (Car) contents in calli (hypocotyl, cotyledon, egg cell) showed statistically significant differences between sugar beet genotypes. Absorption spectra of extracts from green calli did not differ from those obtained from green leaves, while in 'brown' calli the differences were caused by relatively high Car contents. Pigment contents in calli were significantly lower than in leaves.
