| Popis: | Uptake and metabolism of 15N labelled cyanamide by cuttings of grapevine 15N labelled cyanamide was taken up from nutrient solution by rooted grapevine cuttings. Precipitable N in shoots or roots contained up to 2/3 of total supplied 15N. Arginine concentrations were higher during cyanamide feeding than in controls and declined to control levels after transfer into cyanamide free nutrient solution. In arginine extracted from shoots and roots after hydrolysis with 6 M HCl and column chromatography, 6-7 % of l5N originating from cyanamide was recovered.
