In detached harley leaves held at constant temperature in the dark, thereis an increase in "soluble" and a corresponding decrease in "solid" nitrogen. Inmature leaves, glutamine accumulates in the early stages of starvation and laterdecreases concurrently with an increase in asparagine. In detached seedlingleaves, the glutamine content remains low throughout, the sequence of eventsotherwise resembling that found with mature leaves. Changes in the nitrogenousfractions during autolysis, in sterile conditions, of barley leaf tissuediffer greatly from those found with intact detached leaves. "Soluble" nitrogenincreases, but neither amide nor ammonia accumulates.
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.
