In a greenhouse experiment with 25 chrysanthemum cultivars, a significant variation was observed in.

Plants that changed the world: chrysanthemum

In another experiment involving culturing floret rays of a large cinerariifilium flower mutant treated with gamma-ray of Gy, a new small yellow flower mutant was produced. The natural pyrethrins from the daisy-like flower, Tanacetum or Chrysanthemum cinerariifoliumare nonpersistent insecticides of low toxicity to mammals.

Copy and print the QR code to a plant label, poster, book, website, magazines, newspaper etc and even t-shirts.

The results showed total contents of the eight compounds in the samples with seed provenance from Keliyang Xinjiang, China, are higher than in samples from the other five provenances by The pyrethrins are produced in the yellow disc florets[]. The relationship between carbohydrate content and gamma irradiation during rooting cineerariifolium chrysanthemum cuttings.

With this array, we genotyped four bi-parental populations with sizes of53, 76 and 37 offspring plants respectivelyand a cultivar panel of 63 genotypes.

In this study we investigated the conditions of a higher frequency for regenerated plants from different explants of a standard-type chrysanthemum ‘Jinba’. Since commercial production of this ornamental species is strongly affected by fungal diseases such as chrysanthemumwhite rust Puccinia horiana, high doses of fungicides are being used posing increased environmental and commercialcosts.

Efficient plant regeneration system has been developed from the nodal segments of chrysanthemum. The radioactively labelled recombinant DNA was hybridised to crude extracts from avocado leaves and chrysanthemum leaves. Its highly heterozygous state complicates molecular analysis, so it is of interest to derive haploid forms.

By culturing purple florets from selected tall plant resulting from The plant morphology, genomic, transcriptomic, and epigenetic changes between chfysanthemum and diploid plants were investigated.


Chromosome counts and microsatellite fingerprinting showed that only one of the regenerants was a true haploid.

Ligulate flower, tubular flower and leaves of tetraploid plants were greater than those of the diploid plants. Pyrethrum flowers and pyrethroid insecticides.

Induction of in chrysanthdmum mutation in chrysanthemum Dendranthema grandiflora Tzvelev cv.

SSR marker development and intraspecific genetic divergence exploration of Chrysanthemum indicum based on transcriptome analysis. The close affinity of Golovinomyces to Artemisia and Chrysanthemum species signifies a coevolutionary event between the powdery mildews concerned and their host species in the cinerarriifolium Artemisiinae Asteraceae tribe Anthemideae.

The model developed uses Richards’ growth equation Richards, as its base. Therefore, methods must be developed to predict vase life of cut flowers. In vitro cultures of Taihei variety were irradiated with chronic gamma rays of Full Text Available High salinity seriously affects the production of chrysanthemumso improving the conerariifolium tolerance of chrysanthemum becomes the focus and purpose of our research.

Genomic dosage highly correlated with relative allele coverage from the RNA sequencing data, indicating that most alleles are expressed according to their genomic dosage. As well as protecting crops and flowers, pyrethrum can induce abnormal behaviour in female mosquitoes, making them unable to bite normally — this could have wider implications for human health. A total of in silico SSR loci were identified from C. Here, a greenhouse comparison was made of cinerariiflium Fusarium wilt control efficacy of various treatments given to a soil in which chrysanthemum had been produced continuously for many years.

Bacillus thuringiensis Baculovirus Beauveria bassiana Beauveria brongniartii Metarhizium acridum Metarhizium anisopliae Nomuraea rileyi Lecanicillium lecanii Paecilomyces fumosoroseus Paenibacillus popilliae Purpureocillium lilacinum. It was found that the 24 cultivars averagely had 3. Results showed that all treatments had positive effects on the vase life of flowers.

The daisy-like flowers of pyrethrum Tanacetum cinerariifolium are used to extract pyrethrins, a botanical insecticide with a long history of safe and effective use.

People can be exposed to pyrethrum as a mixture of cinerinjasmolinand pyrethrin in the workplace by breathing it in, getting it in the eyes or on the skin, or swallowing it. Cut flowers show a wide variance of keepability.


The effect of chrysanthemum leaf trichome density and prey spatial distribution on predation of Tetranychus urticae Acari: Agrobacterium-mediated inoculation of chrysanthemum Chrysanthemum morifolium plants with chrysanthemum stunt viroid. Views Read Edit View history. This was done by measuring biochemical and physiological parameters as a function of time after irradiation.

Purified virus preparation yielded rather straight rod and flexuous virus particles of about nm long and 12 nm wide. Some members of the genus Chrysanthemumsuch as the following two, are placed in the genus Tanacetum instead by some botanists. Eukaryotic translation initiation factor 4E eIF4E plays an important role in plant virus infection as well as the regulation of gene translation. There is large genotypic variation in susceptibility to disk floret degreening. Induced mutation altering flower colour in Chrysanthemum.

Chrysanthemum morifolium are reviewed. Since CVB is considered a new plant virus in chrysanthemum plantation in Indonesia, a study on its molecular characters is required. Direct shoot regeneration from the leaf and flower explants was obtained 21 to 28 days after the initial culture. Thus, the objective of this work was to evaluate the production and quality of chrysanthemum varieties cultivated in pots with different NPK rates. Meanwhile, an ultra performance liquid chromatography coupled with electrospray ionization and quadrupole time-of-flight-mass spectrometry UPLC-ESI-QTOF-MS was also employed to rapidly separate and identify flavonoids and phenolic acids in snow chrysanthemum from Keliyang.

The major components were camphor On the other hand, developed countries, as USA and Japan, have a rigorous phyto sanitary inspection to prevent the introduction of new plagues and diseases through fresh products. Variation between cut chrysanthemum cultivars in response to suboptimal temperature. Meanwhile, we observed higher expression levels in the leaves contrasted with other tissues.
