The basidiome stage of Armillaria gallica can be a genetic mosaic. Ten cells isolated from a single basidiome in 1986 produced nine different genotypes when analyzed for variation at six nuclear loci. Four additional basidiomes collected in 1986 produced mosaic patterns when analyzed for variation at a single nuclear (PCR-RFLP) locus. One basidiome collected in 1993 was not a genetic mosaic bec...

Pine wilt disease (PWD), a destructive disease for pine trees, is caused by the pine wood nematode (PWN), Bursaphelenchus xylophilus and additional bacteria. In this study, extracts of Zostera marina showed a high nematicidal activity against PWN and some of the bacteria that it carries. Light yellow crystals were obtained from extracts of Z. marina through solvent extraction, followed by chrom...

Light controls bud burst in many plants, which subsequently affects their architecture. Nevertheless, very little is known about this photomorphogenic process. This study ascertains the effects of light on bud burst and on two of its components, i.e. growth of preformed leaves and meristem organogenesis in six cultivars from three Rosa species (R. hybrida L., R. chinensis L., R. wichurana L.). ...

Comparative analysis of development and survivorship of two geographically divergent populations of the Natal fruit fly Ceratitis rosa Karsch designated as Ceratitis rosa R1 and Ceratitis rosa R2 from Kenya and South Africa were studied at seven constant temperatures (10, 15, 20, 25, 30, 33, 35 °C). Temperature range for development and survival of both populations was 15-35 °C. The development...

Background: Rosa Canina L. is a medicinal plant with many therapeutic applications in traditional medicine. This study aimed to evaluate the effectiveness of the extract of Rosa Canina on liver function, lipid profiles and thyroid hormones in hypercholesterolemic rats. Methods: In this experimental study, 60 male Wistar rats were divided into...

Rosehip is among the most important plants with high economic value, mainly used in foods and beverages from ancient times to present. In this study, Rosa canina L. pimpinellifolia roots, consumed as tea Aktoprak Village of Erzurum province, were collected together fruits. The main goal study was investigate vitro bioaccessibility phenolic compounds roots fruits R. by a simulated gastrointestin...
