Název v původním jazyce

Endogenous cytokinins in Cocos nucifera L. in vitro cultures obtained from plumular explants.

Popis výsledku v původním jazyce

Embryogenic calli and non-embryogenic calli can be formed from the initial calli. Fourteen cytokinins were analysed in the three types of calli and all the cytokinins were found in each type. The most abundant cytokinins in each type of callus were isopentenyladenine-9-glucoside, zeatin-9-glucoside, zeatin riboside, isopentenyladenine riboside, dihydrozeatin and dihydrozeatin riboside in decreasing order. Total cytokinin content was found to be lower in embryogenic calli compared to non-embryogenic calli or initial calli. When explants were cultured in media containing exogenously added cytokinins, the formation of embryogenic calli in the explants was reduced. When 8-azaadenine (an anticytokinin) was added the formation of embryogenic calli and staticembryos was increased. These results suggest that the difference in somatic embryo formation capacity observed between embryogenic calli and non-embryogenic calli is related to their endogenous cytokinin contents.
