Chrysanthemum has been cultivated for more than 2000 years and today, it is the world’s second most economically important floricultural crop following the rose (Teixeira da silva, 2003). Due to high popularity and demand for chrysanthemum it has become one of the first commercial targets for Micro propagation and thus tissue culture can be utilized for its large scale production. Regeneration ...

WRKY transcription factors are known to function in a number of plant processes. Here we have characterized 15 WRKY family genes of the important ornamental species chrysanthemum (Chrysanthemum morifolium). A total of 15 distinct sequences were isolated; initially internal fragments were amplified based on transcriptomic sequence, and then the full length cDNAs were obtained using RACE (rapid a...

Chrysanthemum is an important ornamental plant which is increasingly being monocropped. Monocropping is known to affect both fungal abundance and species diversity. Here, quantitative PCR allied with DGGE analysis was used to show that fungi were more abundant in the rhizosphere than in the bulk soil and that the fungal populations changed during the growth cycle of the chrysanthemum. The major...

This paper describes work being carried out at the National Institute of Agricultural Botany to develop a machine vision system that assesses the shape of chrysanthemum leaves as part of the testing procedure applied to new chrysanthemum varieties before they are granted protection under the UK’s Plant Breeder’s Rights Scheme. After outlining the testing procedure and the characters used to des...

The antioxidant activity of aqueous extracts of fresh leaves of costmary (Chrysanthemum balsamita L.) was investigated. The effect of the extraction time on total phenolic compounds (TPhC) and antioxidant activity (ABTS -, CUPRACand FRAP assays) was studied. Results demonstrated highest levels of TPhC (0.60 GAE/g fresh plant weight), CUPRAC (5.93 μMTE/g FW), ABTS (10.68 μMTE/g FW), and FRAP (7....

The relationship between phosphorus (P) uptake and growth rate of chrysanthemum plants grown hydroponically for cut flowers was investigated. In Exp. 1, fresh weight increase of chrysanthemum cv. Seiun plants at flower budding phase administered 0 to 40 ppm in culture solution for 16 days was evaluated. 1. P uptake by the chrysanthemum plants was nearly proportionate to P concentration in the c...

Annual Chrysanthemum (Chrysanthemum coronarium L.) is one of the most widely cultivated garden flowers and highly suitable for loose flower, pot culture bedding purposes. The objective this research was to evaluate effect different mycorrhizal strains vermicompost on growth flowering coronarium. treatments comprise 4 mycorrhiza (No application, Glomus mosseae, Acaulospora laevis, Gigaspora marg...
