This study was conducted to assessthegenetic variety of 12 damask rosegenotypes of Kurdistan using morphological traits in Zaleh Research Farm affiliated to Kurdistan Province Agriculture Research Center. The experiment was carried out as a randomized complete block design with three replications and each replication included three stocks in each genotype. Results of analysis of variance showed...

A field experiment was conducted during two successive seasons 2010 and 2011 to determine the influence of rabbit manure rats( 5,10 and 15 m / fed.) and bio-fertilizers. The biofertilizer used was Bacillus sirculans (B.S) (used as seedlings inoculants) and vesicular arbuscular mycorrhizal fungi (VAM) (used as soil inoculants) and their interactions on periwinkle (Catharanthus roseus , L. G. Don...

Forage brassica (Brassica napus cv. Greenland) is bred for vegetative growth and biomass production, while its seed yield remains to be improved for seed producers without affecting forage yield and quality. Cytokinins affect seed yield by influencing flower, silique and seed number, and seed size. To identify specific cytokinin gene family members as targets for breeding, as well as genes asso...

Context: Barleria prionitis L. (Family Acanthaceae; commonly known as Vajradanti), is an annual shrub, 1–3 feet high, found throughout tropical Asia and in South Africa. Objective: The aim of the present study was to evaluate the antioxidant activity of 50% ethanolic extract of leaf, flower, and stem of B. prionitis by using β carotene bleaching assay, reducing power and free radical scavenging...

Flowering control is one of the several strategies for gene containment of transgenic plants. TERMINAL FLOWER 1 (TFL1) is known to be involved in the transcriptional repression of genes for inflorescence development. Two TFL1 transcripts with different 3' UTR were cloned from black cherry (Prunus serotina Ehrh.) using reverse transcription-polymerase chain reaction (RT-PCR) and rapid amplificat...

The mechanisms that establish the floral meristem are now becoming clearer, but the way in which flowering is maintained is less well understood. Impatiens balsamina provides a unique opportunity to address this question because reversion to vegetative growth can be obtained in a predictable way by transferring plants from inductive to non-inductive conditions. Following increasing amounts of i...

Current understanding of floral development is mainly based on what we know from Arabidopsis (Arabidopsis thaliana) and Antirrhinum majus. However, we can learn more by comparing developmental mechanisms that may explain morphological differences between species. A good example comes from the analysis of genes controlling flower development in pea (Pisum sativum), a plant with more complex leav...

Genetically modified (GM) cotton plants that effectively control cotton boll weevil (CBW), which is the most destructive cotton insect pest in South America, are reported here for the first time. This work presents the successful development of a new GM cotton with high resistance to CBW conferred by Cry10Aa toxin, a protein encoded by entomopathogenic Bacillus thuringiensis (Bt) gene. The plan...

The genus Tanacetum L. belongs to the Asteraceae family and Anthemideae tribe is one of the most important medicinal plants that contains 26 species in Iran, 12 of them are endemic. This paper reports the essential oil composition of Tanacetum uniflorum (Fisch. & C.A. Mey. ex DC.) Sch.Bip. growing spontaneously in Salmas (North-West of Iran). Essentail oil extracted by water distillation and st...
