Production de composés indoliques rhizogènes par le ver de terre Lumbricus terrestris

摘要: In vitro application of total gross extract earthworms (Lumbricus terrestris) in diverse dilutions stimulates rhizogenesis young bean plants (Phaseolus vulgaris). The observed effect is similar to that indol acetic acid, a well-known growth enhancer plants, used here as control various concentrations. Fragmentation worm by column chromatography results three groups fractions. Only the polar group fractions has significant rhizogenous effect, which is, however, inferior presence worms or acid. Gross analyses using thin layer chromatography, with appropriate systems and reagents, revealed acid not present, but probably replaced other indol-derived substances have neutral basic chromatographic behaviour. These presumed are identified methyl-tryptophane, serotonin, hydroxy-indol Analyses mass spec...
