TL;DR: In this paper, three rates of nitrogen fertilization were studied: 0, 100 and 140 kgN/ha, as well as two modes of plant formation: single and two-stemmed plants.
Abstract: A trial with large the flowered chrysanthemum cultivar Dark Westland was carried out in an unheated greenhouse. Three rates of nitrogen fertilization were studied: 0, 100 and 140 kgN/ha, as well as two modes of plant formation – single- and two-stemmed plants. Parameters of the biometric characteristics, leaf gasexchange and leaf pigment content were determined. The best results about growth and decorative behaviour were achieved at nitrogen fertilization level of 100 kgN/ha. It was established that nitrogen fertilization in rates of 100 and 140 kgN/ha enhances photosynthetic rate in both modes of plant formation.

Abstract: The invention discloses feed additives for preventing carassius auratus gibelio from being infected by carp herpes viruses. The feed additives comprises, by weight, 20-25 parts of semen plantaginis, 7-10 parts of smilax glabra, 15-20 parts of purslane, 10-14 parts of chrysanthemum indicum, 10-14 parts of eucommia, 6-10 parts of white peony root, 3-6 parts of cirsium japonicum, 2-5 parts of hawthorn, 2-5 parts of fructus mume, 8-10 parts of yam and 0.5-1.5 parts of zeolite powder. According to the feed additives, the anti-infection capability of the carassius auratus gibelio against the carp herpes viruses is effectively improved.

Abstract: The invention provides a composition for treating hairline sore. The composition is characterized by being prepared from an oral drug and an externally-applied drug, wherein the oral drug is prepared by the following steps of soaking the following raw materials by weight: 30g of coix seed, 30g of small red bean, 15g of honeysuckle, 10g of chrysanthemum indicum, 15g of artemisia capillaries, 30g of loosestrife, 10g of scutellaria, 10g of balloonflower, 15g of salvia and 10g of glycyrrhiza by water, decocting, and removing slag to obtain a filtrate; the externally-applied drug is prepared from the following Chinese medicinal materials by weight: 50g of argy wormwood, 50g of chrysanthemum indicum and 100g of small red bean and is prepared by the following steps of mixing the Chinese medicinal materials, sunning or drying, grinding a mixture into powder, screening by a 150-mesh sieve, and regulating into a pasty shape by adding vinegar to be used for external application. The composition has the characteristics of definite therapeutic effect, safety, convenience, no toxic and side effects and low cost.

TL;DR: In this article, the authors identify three distinct genetic clusters corresponding to the three taxa: C. indicum, C. vestitum and C. latifolium.
Abstract: Understanding hybridization and introgression between natural plant populations can give important insights into the origins of cultivated species. Recent studies suggest differences in ploidy may not create such strong reproductive barriers as once thought, and thus studies into cultivated origins should examine all co-occurring taxa, including those with contrasting ploidy levels. Here, we characterized hybridization between Chrysanthemum indicum, Chrysanthemum vestitum and Chrysanthemum vestitum var. latifolium, the most important wild species involved in the origins of cultivated chrysanthemums. We analysed population structure of 317 Chrysanthemum accessions based on 13 microsatellite markers and sequenced chloroplast trnL-trnF for a subset of 103 Chrysanthemum accessions. We identified three distinct genetic clusters, corresponding to the three taxa. We detected 20 hybrids between species of different ploidy levels, of which 19 were between C. indicum (4x) and C. vestitum (6x) and one was between C. indicum and C. vestitum var. latifolium (6x). Fourteen hybrids between C. indicum and C. vestitum were from one of the five study sites. Chrysanthemum vestitum and C. vestitum var. latifolium share only one chloroplast haplotype. The substantially different number of hybrids between hybridizing species was likely due to different levels of reproductive isolation coupled with environmental selection against hybrids. In addition, human activities may play a role in the different patterns of hybridization among populations.

TL;DR: In this article, the wild chrysanthemum flower seeds are creatively directly sowed or drill-sowed in a wetland field, the wetland can ensure that the surface soil is moist for a long time, so that the seeds are easy to absorb water, and the problem of water shortage does not occur in the seed roots after the seeds absorb water and germinate is solved.
Abstract: The invention belongs to the technical field of wild chrysanthemum cultivation, in particular to a wild chrysanthemum planting method. According to the method, wild chrysanthemum flower seeds are creatively directly sowed or drill-sowed in a wetland field, the wetland can ensure that the surface soil is moist for a long time, so that the seeds are easy to absorb water, and the problem of water shortage does not occur in the seed roots after the seeds absorb water and germinate is solved, the phenomenon that the seeds are sun-dried or dry after absorbing water and swelling is avoided, and the problem that the seeds are difficult to germinate and absorb water is solved; if the seeds are sown in wetland and covered with soil, with the seed weight of chrysanthemum indicum being only 0.1g, cotyledons are difficult to excavate; and by arranging drainage ditches in the wetland, the drainage property of the wetland can be ensured, the problem of stagnant water and dead seedlings cannot occur during the growth of the wild chrysanthemum, the wild chrysanthemum can normally grow, and the survival rate of the wild chrysanthemum is ensured.
