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...

Mass spectrometry imaging (MSI) by laser ablation electrospray ionization (LAESI) enables the lateral mapping of molecular distributions in untreated biological tissues. However, direct sampling and ionization by LAESI–MSI limits the differentiation of isobaric ions (e.g., structural isomers) in a complex sample. Ionmobility separation (IMS) of LAESI-generated species is sufficiently fast to be...

Pelargonium species are native to South Africa, and they have a long history in medicinal use. This study aimed extract essential oils from different parts of P. peltatum, determine the chemical composition oils, assess oils’ biological potential as analgesic anti-inflammatory agents. The were obtained by hydro-distilling profile was determined GC-FID GC-MS. activity oil using tail immersion ho...

Plant-derived pharmaceuticals have become prominent in the market place, making it a favored healthcare choice. In this study, air dried samples of aerial parts of Pelargonium X fragrans Willd. and Pelargonium peltatum L’Hérit. were separately extracted using successive extraction with a soxhlet apparatus. Each extract was tested for its antimicrobial activity using two Gram-negative bacterial ...

Despite the increasing acceptance of traditional medicines in peri-urban areas in South Africa, this rich indigenous knowledge is not adequately documented. Therefore, an ethnobotanical study was undertaken to document medicinal plants grown and maintained in per-urban domestic gardens in the Capricorn District, Limpopo Province. Semi-structured interviews, observation and guided walks with 62 ...

lehmannia valentiana is one of the most important pests of ornamental plants, vegetables and other agricultural crops, which causes noticable damages. in a food experiment four kinds of food for 24 and 72 hours were offered. the preferences of food were amaranthus tricolor, cineraria grandiflora, pelargonium peltatum, rosa damascena and l. valentiana. the l. valentiaiia is active the whole year...
