title: Effect of Theophylline on Elongation and some Transport Processes in Embryos of Haplopappus gracilis.
abstract: In germinating embryos of Haplopappus gracilis, theophylline induced a FC-reversible inhibition of elongation and K(+) uptake. The possible action of theophylline on the proton pump and other transport processes is discussed and compared with the effects of its ethylenediamine salt, aminophylline.
