Änderungen im Gehalt an löslichen Zuckern und Zellwandkohlenhydraten während der Hemmung endogenen Zellstreckungswachstums durch Antimetaboliten

摘要

The effect of actinomycin D, hydroxyproline, cycloheximide, and chloramphenicol on the soluble sugar and cell-wall carbohydrate content was studied in an effort to look for the primary action of these antimetabolites on the cell-wall in connection with cell elongation during inhibition of endogenous hypocotyl growth in mustard seedlings (Sinapis albaL.). The experiments have been done under steady state conditions as far as the parameters under examination are concerned. During the experimental period hypocotyl elongation is due almost exclusively to cell elongation (Geiser, 1964). Antimetabolite concentrations in an 1 hr feeding period have been chosen to effect about 70 relative inhibition 12 hrs after feeding.
