Conversion of Dihydroflavonols to Flavonols with Enzyme Extracts from Flower Buds of Matthiola incana R. Br
Dioxygenase, Flavonoid Biosynthesis, Flavonols, Matthiola incana Soluble enzyme preparations from flower buds of Matthiola incana catalysed the conversion of dihydrokaempferol to kaempferol and of dihydroquercetin to quercetin. The reaction required 2-oxoglutarate, ascorbate and Fe2+ as cofactors and had a pH-optimum at about 7.0. Highest enzyme activity was already present in the youngest buds...
متن کاملGenetic Control of Chalcone Synthase Activity in Flowers of Matthiola incana R. Br
Anthocyanins, Flavonoids, Chalcone Synthase, Genetic Control, Matthiola incana Chalcone synthase activity was demonstrated in enzyme preparations from flowers of defined genotypes of Matthiola incana (stock). The product formed from 4-coumaroyl-CoA and malonylCoA was naringenin and not the isomeric chalcone, because chalcone isomerase was also present in the reaction mixture. Chalcone synthase ...
متن کاملInfluence of Paclobutrazol on Growth and Flowering of Rhododendron ‘Sir
Shoot extension of Rhododendron ‘Sir Robert Peel’ was reduced, but flowering was more precocious after treatment of plants with paclobutrazol. All of the drench rates tested (0.05 to 0.4 g a.i./pot) proved excessive and resulted in prolonged shoot growth reduction but greatly increased the number of flowers. However, flowers produced at the higher drench rates were grossly malformed and unaccep...
متن کاملEffect of Phosphorus Fertilization on Growth and Flowering of Scaevola aemula R. Br. ‘New Wonder’
Scaevola aemula R.Br. (fanfl ower), an ornamental plant native to Australia, produces stunted growth when fertilized with high concentrations of P. To determine optimum P concentration, rooted cuttings were transplanted into 15 cm standard pots and grown with a water soluble fertilizer, where P concentrations were 0, 14.5, 29.0, 43.5, 58.0, 72.5, 87.0 mg·L–1 and all plants received 200 mg·L–1 N...
متن کاملMicropropagation of Matthiola incana using BA and IBA. Behzad Kaviani
Matthiola incana (Brassicaceae) is an important ornamental plant, which is used as cut flower, pot plant, and landscape. Traditionally, it is propagated via seeds, but interest is given in vegetative propagation of parental lines as well as superior single plants. Micropropagation by organogenesis is an efficient in vitro propagation method for Matthiola incana. Starting from seeds, apical bud ...
