Interspecific Hybridization between Zonal Geranium (Pelargonium* hortorum) and Ivy-leaved Geranium (P. peltatum) Using a Cooling Plate Culture System.

Rare excitatory amino acid from flowers of zonal geranium responsible for paralyzing the Japanese beetle.

The Japanese beetle (JB), Popillia japonica, exhibits rapid paralysis after consuming flower petals of zonal geranium, Pelargonium x hortorum. Activity-guided fractionations were conducted with polar flower petal extracts from P. x hortorum cv. Nittany Lion Red, which led to the isolation of a paralysis-inducing compound. High-resolution-MS and NMR ((1)H, (13)C, COSY, heteronuclear sequential q...

Sensitive and specific detection of Xanthomonas hortorum pv. pelargonii in geranium by real-time PCR

Xanthomonas hortorum pv. pelargonii is the causal agent of bacterial blight of geranium. A specific and rapid real-time PCR assay for detecting the bacterium in plant was developed in this study. We compared sensitivity of conventional and real-time PCR for detection of the pathogen in inoculated plants. For application to disease management programs, PCR amplification must be able to detect la...

Virus Diseases of Geranium

Several diseases of geraniums (Pelargonium species) are caused by viruses. The economic losses caused by these diseases are difficult to assess since infected plants are often symptomless and because both the cultivar and the environment in which the plants are growing can greatly influence the severity of the symptoms. The problem is compounded by the diverse sources of stock plants and the fa...

Effects of Zataria multiflora and Geranium pelargonium essential oils on growth-inhibiting of some toxigenic fungi

The effects of two Iranian medicinal plants including Zataria multiflora and Geranium pelargoniumwere evaluated on growth-inhibiting of some toxigenic fungi such as Aspergillus flavus, A. parasiticus, A.ochraceus and Fusarium verticillioides. In this study, standard Z. multiflora and G. pelargonium essentialoils (EOs) were diluted in 0.01% dimethyl sulfoxide. Different dilutions of Z. multiflor...
