In this study, inter-simple sequence repeats (ISSRs) and sequence-related amplified polymorphism (SRAP) were applied to assess the genetic diversity in 38 species of Chrysanthemum and related genera. A total of 204 and 567 bands were amplified by 24 ISSR and 25 SRAP primers, of which 196 (97%) and 557 (99%) were polymorphic, respectively. The ISSR-based genetic similarity ranged from 0.016 to 0...

—In the Shadow of Young Girls in Flower by Marcel Proust P because chrysanthemums bloom well into the autumn and come in an array of colors and varieties, these hardy flowers have inspired poets, writers, and artists for millennia. French Impressionist artist Claude Monet celebrated this flower in a series of four still-life paintings in 1897, including Chrysanthemum, 1897, selected for this mo...

The effectiveness of 12 chemical compounds (azoxystrobin, carbendazim, chlorothalonil, fenarimol, folpet, mancozeb, myclobutanil + mancozeb, prochloraz + carbendazim, tebuconazole + triadimefon, tetraconazole + chlorothalonil, tiophanate-methyl, tridemorph + epoxiconazole) in the control of Puccinia horiana was tested on chrysanthemum cv. Fiji Yellow. Additionally, their influence on plant grow...

Chrysanthemum indicum flower is a traditional Chinese medicine with strong aroma and many previous studies focused on its essential oil. GC/MS and HPLC were used to determine its volatiles, flavonoids and flavonoid glycosides. Sixty three volatiles were detected and the abundant volatiles included 2,6,6trimethyl-bicyclo[3.1.1]hept-2-en-4-ol, 2-(2,4-hexadiynylidene)-1,6-dioxaspiro[4.4]non-3-ene,...

The flower of Chrysanthemum Morifolium Ramat. (CM) is a useful food and folk medicine in China. Effects of Chrysanthemum Morifolium extracting (CME) conditions, including extraction temperature, extraction time and the ratio of flower to water on infusion quality were investigated. The extractability, liquor color differences and the major flavonoids of luteolin-7-O-beta-D-glucoside and luteoli...

Plant vacuolar Na(+)/H(+) antiporter genes play significant roles in salt tolerance. However, the roles of the chrysanthemum vacuolar Na(+)/H(+) antiporter genes in salt stress response remain obscure. In this study, we isolated and characterized a novel vacuolar Na(+)/H(+) antiporter gene DgNHX1 from chrysanthemum. The DgNHX1 sequence contained 1920 bp with a complete open reading frame of 153...

Development, survivorship, longevity, reproduction, and life table parameters of the glassy-winged sharpshooter, Homalodisca vitripennis (Germar), were examined in the laboratory using three host plants, sunflower (Helianthus annuus L.), Chrysanthemum morifolium L., and euonymus (Euonymus japonica Thurb.). Females deposited similar-sized egg masses on all three plants. Hatching was highest with...

Chrysanthemums (Chrysanthemum×morifolium Ramat.) are an important cut-flower and potted plant crop in the horticultural industry world wide. Chrysanthemums express the flavonoid 3'-hydroxylase (F3'H) gene and thus accumulate anthocyanins derived from cyanidin in their inflorescences which appear pink/red. Delphinidin-based anthocyanins are lacking due to the deficiency of a flavonoid 3', 5'-hyd...

Influences of irrigation frequency on the growth and flowering of chrysanthemum grown under restricted root volume were tested. Chrysanthemum cuttings (Chrysanthemum morifolium "Reagan White") were grown in seedling tray which contained coconut peat in volumes of 73 and 140 cm(3). Plants were irrigated with drip irrigation at irrigation frequencies of 4 (266 mL), 6 (400 mL), and 8 (533 mL) time...

Puccinia horiana Hennings, the causal agent of chrysanthemum white rust, is a worldwide quarantine organism and one of the most important fungal pathogens of Chrysanthemum × morifolium cultivars, which are used for cut flowers and as potted plants in commercial production regions of the world. It was previously reported to be controlled by Lecanicillium lecanii, Cladosporium sphaerospermum, C. ...
