Influence of irradiance on chlorophyll synthesis in Picea abies calli cultures

Abstract

Dark-grown seedlings of Picea abies (L) Karst. are able to accumulate the highest amounts of chlorophyll (Chl) and its precursor protochlorophyllide (Pchlide) in all Pinaceae, but calli derived from 14-d-old green cotyledons of P. abies are completely white during the cultivation in the dark. Pchlide reduction is catalysed in the dark by light-independent… (More)
