Dog rose (Rosa canina) is one of the most important flower crops in the world and has a value in ornamental, pharmaceutical and cosmetic trade. Also it was used as a root stock for other cultivars of Rose. Hence this investigation was attempted with the aim to study direct regeneration of Rosa canina. The experimental data of the present investigation was analyzed statistically by using complet...

We were particularly interested in how bioactive substances are inherited from main species. aim study was to compare ascorbic acid, organic acids, phenolics fruits, hips, Rosa pendulina L. hybrid × spinosissima acid studied higher R. pendulina. total acids s...

Insulin resistance is a condition in which insulin signaling and action are impaired in insulin sensitive tissues and result in hyperglycemia, hyperlipidemia, and type 2 diabetes mellitus. Our previous studies have shown that Rosa damascena has antihyperglycemic effects on diabetic and normal rats. Therefore, we conducted a study to evaluate the effect of this medicinal plant on insulin sensiti...

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.). ...
