Analysis of Variability in the Amaranthus Bioassay for Cytokinins: Effects of Water Stress on Benzyladenine- and Fusicoccin-dependent Responses.

abstract：:The labeling pattern of the sugar moieties of 1-kestose after in vivo pulse labeling with (14)CO(2) was not the same as that after in vitro labeling with (14)C-sucrose. The two fructosyl residues of 1-kestose had similar specific radioactivities after in vitro synthesis, but after in vivo radiolabeling the specific ra...
