1-MCP blocks ethylene-induced petal abscission of Pelargonium peltatum but the effect is transient
Continual exposure to 1.5 ml l ethylene caused 100% petal abscission within 2 h from detached flowers of Pelargonium peltatum (L.) ‘Pink Blizzard’ (ivy geranium) harvested just after the stigmatic lobes had separated. When flowering plants were first pretreated for 2 h with 1 ml l 1-MCP, ethylene-induced petal abscission was completely inhibited. However, the effect was transient, since percent...
متن کاملIntegrated approach for detection of nonculturable cells of Ralstonia solanacearum in asymptomatic Pelargonium spp. cuttings.
Ralstonia solanacearum (biovar 2, race 3) is a soil and water-borne pathogen that causes serious diseases in several solanaceous hosts. It can also infect geranium plants, posing an important threat to their culture when latently infected cuttings are imported from countries where the pathogen is endemic. R. solanacearum can be present in very low numbers in asymptomatic geranium cuttings, and/...
متن کاملThe pollen morphology of Pelargonium endlicherianum and Pelargonium quercetorum (Geraniaceae) in Turkey
The pollen morphology of Pelargonium endlicherianum Fenzl. and Pelargonium quercetorum Agnew. from the family Geraniaceae was examined under light microscopy and scanning electron microscopy. Pollen morphologies are eurypalynous. The pollen grains were tricolporate, prolate-spheroidal and large. Aperture was ectoaperture, colpus was short, and the pores were oblate-spheroidal and large. The exi...
متن کاملIDENTIFICATION AND ELIMINATION OF BACTERIAL CONTAMINANTS FROM Pelargonium TISSUE CULTURES
In our laboratory, bacterial contamination was detected in cultures of Pelargonium x hederaefolium ‘Bonete’ that had been subcultured continuously for several years. Two contaminating bacteria were isolated and identified by partial sequence analysis of 16S rRNA gene as Paenibacillus glycanilyticus and Lactobacillus paracasei. Antibiotic sensitivity testing was performed on the bacterial isolat...
متن کاملBenzopyranones and their sulfate esters from Pelargonium sidoides.
Investigation of the benzopyranones from the roots of PELARGONIUM SIDOIDES led to the identification of 15 benzopyranones, among them the novel compounds 12 and 14. Furthermore, benzopyranones 4 and 15 were detected in PELARGONIUM SIDOIDES for the first time. Structure determinations were performed by one- and two-dimensional NMR spectroscopy. An HPLC system for the discrimination of these benz...
