Seed maturation of Pisum sativum cv. Progress No. 9 proceeds more slowly in winter than in summer even when the parent plants are grown in greenhouse conditions with light-and heat-supplementation. For parent plants grown under "summer" and "winter" conditions the metabolism of [3H]GA9 in cultured s

Gibberellin A9, GA20 and GA29, all known to be endogenous to immature seeds of Pisum sativum cv. Progress No. 9, were fed in tritiated form to seeds of this cultivar cultured in vitro. [(3)H]GA9 was metabolised to [(3)H]GA20, 2Ξ²-OH-[(3)H]GA9, H2-[(3)H]GA31 and a H2-[(3)H]GA31 conjugate. The percenta

The metabolism of GA29 during seed maturation in Pisum sativurn cv. Progress No. 9 was further investigated. [17-~3C1]GA29 was metabolised to a GA-catabolite (structure 3), with incorporation of the [13C] label from the GA29 substrate into the GAcatabolite being demonstrated by GC-MS. Quantitation o

The presence of abscisic and phaseic acid in a purified acidic extract from flowering plants of the long-short-day plant Bryophyllum daigremontianum [(R. Hamet and Perr.) Berg.] was conclusively established by combined gas chromatography-mass spectrometry (GC-MS) of their methyl esters. Gibberellin
