Tobacco Research Laboratory, Federal Research, Science and Education Administration, U.S. Department of Agriculture, Oxford, North Carolina USA
Supplemental calcium applied to tobacco as a NO2 salt delayed leaf senescence induced by ethephon (2-chloroethyl phosphonic acid) treatment. Increases in the concentrations of Ca applied delayed the onset of leaf abscission in a dose-dependent...
