Red-light-enhanced conversion of tritiated gibberellin A9into other gibberellin-like substances in homogenates of etiolated barley leaves

摘要

Irradiation of homogenates of etiolated barley leaves with red light resulted in an increase in the levels of gibberellin (GA)-like substances as compared to dark controls. When homogenates were fed with 3H-GA9there was as incorporation of the radioactivity into a number of other GA's: this process occurred to a greater extent in red light than in darkness, and could be inhibited by boiling the extract prior to addition of the 3H-GA9.
