To provide theoretical basis for the formation of Chrysanthemum indicum resource and quality,the differences in biology,ecology,yield and quality of Ch. indicum population in the wild tending,the cultivated and the wild were analyzed and compared in this study. The results showed that in the aspect of biology,there was no significant difference between the condition of wild tending and cultivated Ch. indicum at the height of plant,both were significantly higher than wild Ch. indicum. In the aspect of ecology,in the condition of wild tending is less likely to occur water logging than cultivated Ch. indicum. In the condition of wild tending is less likely to occur plant diseases and insect pests than Ch. indicum in the condition of wild. In the aspect of production,the average output of the sample of the condition of wild tending was significantly higher than that the condition of artificial cultivation and wild quadrat. There was no significant difference between the three kinds of condition on the traits of capitulum dichasium,the content of buddleoside of the wild tending Ch. indicum was significantly higher than that of 0. 80% required by the Chinese Pharmacopoeia( 2015 edition). Therefore,the artificial supplement and the appropriate artificial management of wild tending is a mode of production to increase the population density of Ch. indicum and obtain high quality and high yield medicinal materials.

This experiment studied the expression pattern of key gene CO in the photoperiod of Chrysanthemum indicum. The CDS sequence of the Ch. indicum CO gene was cloned by RT-PCR. The open reading frame was 1 380 bp in length and encoded 459 amino acids. The bioinformatics analysis results showed that the Ch. indicum CO had higher homology with Ch. lavandulifolium and Artemisia annua,and the CO was more conservative in the same family. The molecular weight of the predicted protein encode by CO is 52. 04 k Da,the p I is 4. 81,the α-helix structure accounted for 17. 65%,the random coil accounted for 76. 69%,the extension chain accounted for 5. 66%,there are no β-fold and signal peptide. The experimental results showed that short-day treatment could increase the expression level of CO gene in Ch. indicum and induce its flowering. The results of qRT-PCR showed that the relative expression of CO gene in different tissues and different treatment periods of Ch. indicum was significantly different. In this paper,we studied the effect of short-day treatment on the expression of key genes in the flowering cycle of Ch. indicum,providing a basis for photoperiod regulation and harvesting period of Ch.indicum.

In this paper, Chrysanthemum morifolium was used as the experimental object, eight different planting periods were set up in field plot experiment from April to August, which were 04-15, 05-19, 05-30, 06-09, 06-19, 07-20, 07-31, 08-15. The effects of different treatments on the occurrence of root rot, agronnmic traits, mineral element absorption and content of effective components of Ch. morifolium in Macheng country of Hubei province were studied. The results showed that delaying the planting time could effectively reduce the diseases occurrence of root rot of Ch. morifolium. With the advance of transplanting period, the plant height, the weight of one hundred flowers and the number of flowers of Ch. morifolium showed a trend of gradual decrease, while the number of primary branches and the thickness of main stem and the primary branch increased first and then decreased. The yield of Ch. morifolium per plant and per mu increased with the advance of the planting period, and the yield per mu increased during the planting period on June 19, which was 91.96% higher than that on April 15. And with the delay of the planting period,the absorption and accumulation of potassium(K) elements was promotes. The content of active ingredients such as chlorogenic acid, rutin, luteolin, and 3,5-O dicoffeoacy lquinic acid in the Ch. morifolium increased significantly and then gradually decreased with the delay of the planting period, which indicates that late planting can significantly improve the quality of Ch. morifolium. Considering factors such as the occurrence of root rot disease, yield and active ingredient content, combined with climatic conditions in the Dabie Mountains in eastern Hubei, the optimum planting period of Ch. morifolium was determined from mid-late June to early July.

In this study, 24 copies of samples of Chrysanthemum morifolium and soil from two main production towns in Macheng city were collected, and the contents of 13 mineral elements, 5 effective components and 14 soil nutrient factors in Ch. morifolium were determined. The enrichment characteristics of available soil nutrients by mineral elements were analyzed and the dominant factors affecting the effective components of Ch. morifolium were screened. The results showed that the content of mineral elements and soil nutrients and effective components are very different, and variation of soil fertility was much greater than that of inorganic elements in chrysanthemum plants. In general, the level of element content in Ch. morifolium from different producing areas is K>N>P>Mg>Ca>Fe>Mn>Zn>Cu>Ni>Cr>Pb>Cd. The content of K, N and Mg is higher than that of common crops, and the content of Cu, Cd and Pb in Ch. morifolium from various producing areas does not exceed the relevant standards. The N, P and K enrichment capacity in soil was stronger than that of other elements, and the Ca enrichment ability was the worst. The content of AvCu in the soil was positively correlated with the contents of N, Mg, K, Fe and Cu elements in Ch. morifolium. The contents of chlorogenic acid, luteolin, 3,5-O-dicaffeoylquinic acid reached the pharmacopoeia standard. The percentage of chlorogenic acid and 3,5-O-dicaffeoylquinic acid in Ch. morifolium that from Huangtugang town in the active components were generally higher than that from Futianhe town, and the diffe-rences of luteolin contents in the two producing areas were relatively small. The correlation and regression analysis showed that the contents of Cu, Zn and Cr in Ch. morifolium were positively correlated with the active components, while the contents of Fe, Mn and Ni were negatively correlated with the contents of AvP, AvK, TK, AvMn and AvCu in soil. In general, Zn and Ca fertilizer should be added to the ecological planting of Ch. morifolium, K fertilizer should be added, and N and P fertilizer should be applied appropriately.

The fruiting body pattern is an important agronomic trait of the edible fungus Auricularia auricula-judae, and an important breeding target. There are two types of fruiting body pattern: the cluster type and the chrysanthemum type. We identified the fruiting body pattern of 26 test strains, and then constructed two different near-isogenic pools. Then, we developed sequence characterized amplified region (SCAR) molecular markers associated with the fruiting body pattern based on sequence-related amplified polymorphism (SRAP) markers. Ten different bands (189–522 bp) were amplified using 153 pairs of SRAP primers. The SCAR marker “SCL-18” consisted of a single 522-bp band amplified from the cluster-type strains, but not the chrysanthemum strains. This SCAR marker was closely associated with the cluster-type fruiting body trait of A. auricula-judae. These results lay the foundation for further research to locate and clone genes controlling the fruiting body pattern of A. auricula-judae.

The Cd stress of Chrysanthemum indicum was treated by different concentrations of Cd Cl2 solution in the culture substrate. The content of Cd in different parts of Ch. indicum and the content of buddleoside and the total flavonoids in Ch. indicum were determined. The absorption characteristics of Cd elements in Ch. indicum were analyzed. And the influence of Cd elements on the quality of the herbs. The results showed that the application of soil Cd in the range of 0-100 mg·kg~(-1) had no significant effect on the biomass of Ch. indicum,and the root-shoot ratio showed a decreasing-increasing-decreasing trend. The content of Cd in different parts of Ch. indicum was significantly different,and the content of aboveground part was higher than that of underground part. The enrichment factors of Cd elements in different parts of Ch. indicum are different. The enrichment coefficient of aboveground parts is larger than that of underground parts. The whole parts and plants show an increase first and then decrease,and the overall enrichment factor is greater than1. The transfer coefficient of the aerial part/underground part of Ch. indicum showed a decreasing-increasing-decreasing-increasing trend with the increase of the amount of Cd applied in the soil,and the transfer coefficient was higher than 1. The contents of buddleoside and total flavonoids in Ch. indicum after Cd stress treatment were lower than the control,and the overall performance was lower and then increased,but it was still significantly lower than the control,indicating that Cd pollution directly led to the decrease of chemical quality of Ch. indicum.

Chrysanthemi Indici Flos(CIF), the capitulum of Chrysanthemum indicum, is widely used in proprietary Chinese medicine and daily chemical products. At present, CIF is mainly produced from wild resources and rarely cultivated. This study aims to reveal the correlations between linarin content in CIF and climatic factors in different habitats, and provide a theoretical basis for suitable zoning and rational production of medicinal materials. The content of linarin in CIF was determined by HPLC. Grey relational analysis and Pearson correlation analysis were carried out for linarin content with climatic factors. The results showed that the content of linarin in CIF was significantly different among different habitats. The grey relational degrees of climatic factors with linarin content was in an order of average annual precipitation>annual average sunshine hours>annual average temperature>longitude>annual frost-free period>latitude>altitude. Longitude, annual average temperature and average annual precipitation had significantly positive correlations with the content of linarin in CIF, whereas latitude and altitude showed negative correlations with it. The annual frost-free period and annual average sunshine hours had no significant correlation with the content of linarin in CIF. The content of linarin in CIF varied significantly in different habitats. High longitude, low latitude, low altitude, high annual average temperature and high annual average precipitation could be used as indicators for the habitats of high-quality Ch. indicum. This study provides a reference for selecting suitable producing areas of Ch. indicum and establishing artificial cultivation system.

Ajania belonging to the subtribe Artemisiinae of Anthemideae(Asteraceae) is a genus of semi-shrubs closely related to Chrysanthemum. There are 24 species of Ajania in northwestern China, most of which are folk herbal medicines with strong stress tolerance. Modern medical studies have demonstrated that the chemical constituents of Ajania mainly include terpenoids, flavonoids, phenylpropanoids, alkynes, and essential oils. These compounds endow the plants with antimicrobial, anti-inflammatory, antitumor, antimalarial, antioxidant, and insecticide effects. In this study, we reviewed the research progress in the chemical constituents and pharmacological activities of Ajania, aiming to provide reference for the further research and development of Ajania.

OBJECTIVETo study the effects of Chrysanthemum morifolium based on functional diversity in soil microbial community with different cropping system and fertilization and offer scientific basis for the establishment of the reasonable planting patterns.
METHODCombined yield and quality of Ch. morifolium, 8 treatments of different cropping system and fertilization on functional diversity in soil microbial community of Ch. morifolium were investigated by the Biolog.
RESULTThe AWCD of Ch. morifolium paddy-dryland rotation was higher than that of the continuous cropping, the AWCD of organic fertilizer and compound NPK > single organic fertilizer > single compound NPK > no fertilizer. The principal component analysis about Ch. morifolium soil microbial carbon source use showed that the contribution rate of principal component 1 was 45.5% and principal component 2 was 12.1%, which could explain most information about the variation. Different cropping system of Ch. morfolium differentiated in principal component 1 axis, different fertilization differentiated in principal component 2 axis. The yield of Ch. morifolium and volatile oil content paddy-dryland rotation was significantly higher than that of continuous cropping.
CONCLUSIONThe Ch. morifolium should be cultivated with organic fertilizer and compound NPK by paddy-dryland rotation patters.
