Brinckmann, E., Hartung, W. and Wartinger, M. 1990. Abscisic acid levels of individual leaf cells. -Physiol. Plant. 80: 51-54.Abscisic acid (ABA) concentrations of guard cells, subsidiary cells and epidermis cells of Commelina communis L. and Tradescantia virginiana L. were determined in cell sap samples extracted by means of micro glass capillaries. Concentrations up to 6.7 mAf were indicated by commercial immunoassay test kits. A gradient of ABA concentration was found between guard celis (2.49 ±1.81 mAf, n = 25), subsidiary cells (1.25 ± 1.46 mM, n = 21) and epidermis cells (0.86 ± 0.76 mM, n = 20; mean values ± SD).

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
