✦ Synopsis


Movement of 2-[(14)C]ABA through 1.5 cm and 5 cm long root segments of P. coccineus L. was acropetally polarised. The velocity of acropetal transport of [(14)C]ABA in 1.5 cm long segments was 4-5 mm·h(-1). Up to 11 h after the start of incubation [(14)C]ABA could be extracted unchanged. Beyond this time radioactivity became associated to an unidentified compound, which shows chromatographic qualities similar to those of Milborrow's "Metabolite C" (Biochemistry & Physiol. Plant Growth Substances, 1531, Runge Press Ottawa, 1968; and Chem. Comm. 966, 1969).

Light promotes the acropetal movement of 2-[(14)C]ABA through root segments of Phaseolus coccineus L. The promotion occurs only when the segments are irradited during the transport period. Red light and blue light are as effective as white light. There is no significant promotion when the segments a

## Abstract Grüne und durch Belichten ergrünte etiolierte Gerstenkeimlinge bauen Essigsäure‐[2‐^14^C] überwiegend in den Chlorophyllidteil des Blattgrüns ein. Mevalonsäure‐[2‐^14^C] dient dagegen fast ausschließlich der Synthese des Phytols. Sie wird in viel stärkerem Maße als Essigsäure auch zur B
