STUDY OF CHLOROPHYLL a AND b IN ETIOLATED AND ANDROGENIC PLANTS OF BARLEY (Hordeum vulgare L.)

Abstract

In order to characterize the occurrence of albino plantlets during the androgenetic process in barley (Hordeum vulgare L.), chlorophyllous content of microspore derived structures were analyzed in various cultivar. The dynamics of quantities of a and b chlorophylls and their relations within etiolated and androgenic plants of the contrasting cultivars of Igri and Cork have been compared.Research on chlorophyll content dynamics showed that the androgenic plants of cv. Igri accumulated a higher content of chlorophyll compared to the regenerants of cv. Cork. This deficiency of chlorophyll in regenerants may be directly related to a high number of albinos in the anther culture of cv. Cork
