“…It is of great value to highlight that chrysanthemum is a salinity tolerant plant; whose EC values range from 1.3 to 2.5 mS cm -1 . The observed values in this study did not cause symptoms of toxicity in the plants, since most varieties tolerate EC values above 2.5 mS cm -1 , as observed by Barbosa et al (2000) and Barbosa et al (2015).…”

Chrysanthemum can be grown for cutting or as a pot plant year-round, providing a constant production flow. In Brazil, little is known about mineral nutrition and fertilization for this crop. Thus, the objective of this work was to evaluate the production and quality of chrysanthemum varieties cultivated in pots with different NPK rates. The experiment was conducted in a completely randomized design with the NPK rates (10-10-10) of 3 g L -1 , 6 g L -1 and 9 g L -1 and chrysanthemum varieties Sheena, Calabria and Indianapolis. Pots of 1.2 L capacity were filled with substrate and placed three cuttings per pot kept in a fog chamber under long days. After 21 days, apical pruning was done and started the short-day period. After flowering induction, short days were suspended. It was realized analysis of variance and it was noticed that stem length and EC were affected by NPK rates. It was observed an inverse relation between the increase in NPK rate and cultivation cycle, resulting in precocity of flowering for all varieties. Plants cultivated under 9 g L -1 rate did not present toxicity symptoms, suggesting that this dose was more adequate for the production of pot plants for all three varieties. Keywords: Dendranthema grandiflora Tzvelev, floriculture, electrical conductivity, mineral nutrition. RESUMO Produção e qualidade de três variedades de crisântemo em vaso sob diferentes doses de NPKO crisântemo pode ser cultivado para produção de flores de corte ou como planta para vaso durante o ano todo, proporcionando um fluxo de produção constante. No Brasil, as informações a respeito da nutrição mineral e adubação para a cultura são ainda pouco frequentes. Assim, o objetivo do trabalho foi avaliar a produção e qualidade de plantas de três variedades de crisântemo cultivadas em vaso sob diferentes doses de NPK. O experimento foi conduzido em delineamento inteiramente casualizado com as doses de NPK (10-10-10) 3 g L -1 , 6 g L -1 e 9 g L -1 e as variedades Sheena, Calabria e Indianapolis. Vasos de 1,2 L foram preenchidos com substrato e utilizadas três estacas por vaso e mantidos em câmara de nebulização sob dias longos (DL). Após 21 dias, foi realizada a poda apical e iniciou-se o fornecimento de dias curtos (DC). Após a indução do florescimento, o DC foi suspenso. Realizouse análise de variância, constatando-se que o comprimento das hastes e a condutividade elétrica foram afetados pelas doses de NPK. Observou-se relação inversa entre aumento da dose de NPK e ciclo de cultivo, resultando na redução do ciclo para as três variedades. As plantas cultivadas sob a dosagem de 9 g L -1 não apresentaram sintomas de toxidez, sugerindo que esta dose foi mais adequada para a produção de plantas em vaso de alta qualidade para as três variedades. Palavras-chave: Dendranthema grandiflora Tzvelev, condutividade elétrica, floricultura, nutrição mineral.

“…Many plants can grow in hydroponic systems [ 17 – 30 ]. For crops, the quality of produce, taste and the nutritive value of the end products is generally higher in hydroponic systems than in natural soil cultivation.…”

“…Changing the hydroponic medium enables adjustment of plant nutrients at any time. Hydroponic culture has been used for many cereal crops [18][19][20][21][22], fruits [22], vegetables [23][24][25][26][27][28][29], and flowers [30]. In some cases, hydroponic cultivation improves yield and quality [22][23][24][25][26][27][28][29][30].…”

Background Flowers of Chrysanthemum × morifolium Ramat. are used as tea in traditional Chinese cuisine. However, with increasing population and urbanization, water and land availability have become limiting for chrysanthemum tea production. Hydroponic culture enables effective, rapid nutrient exchange, while requiring no soil and less water than soil cultivation. Hydroponic culture can reduce pesticide residues in food and improve the quantity or size of fruits, flowers, and leaves, and the levels of active compounds important for nutrition and health. To date, studies to improve the yield and active compounds of chrysanthemum have focused on soil culture. Moreover, the molecular effects of hydroponic and soil culture on chrysanthemum tea development remain understudied. Results Here, we studied the effects of soil and hydroponic culture on yield and total flavonoid and chlorogenic acid contents in chrysanthemum flowers (C. morifolium ‘wuyuanhuang’). Yield and the total flavonoids and chlorogenic acid contents of chrysanthemum flowers were higher in the hydroponic culture system than in the soil system. Transcriptome profiling using RNA-seq revealed 3858 differentially expressed genes (DEGs) between chrysanthemum flowers grown in soil and hydroponic conditions. Gene Ontology (GO) enrichment annotation revealed that these differentially transcribed genes are mainly involved in “cytoplasmic part”, “biosynthetic process”, “organic substance biosynthetic process”, “cell wall organization or biogenesis” and other processes. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis revealed enrichment in “metabolic pathways”, “biosynthesis of secondary metabolites”, “ribosome”, “carbon metabolism”, “plant hormone signal transduction” and other metabolic processes. In functional annotations, pathways related to yield and formation of the main active compounds included phytohormone signaling, secondary metabolism, and cell wall metabolism. Enrichment analysis of transcription factors also showed that under the hydroponic system, bHLH, MYB, NAC, and ERF protein families were involved in metabolic pathways, biosynthesis of secondary metabolites, and plant hormone signal transduction. Conclusions Hydroponic culture is a simple and effective way to cultivate chrysanthemum for tea production. A transcriptome analysis of chrysanthemum flowers grown in soil and hydroponic conditions. The large number of DEGs identified confirmed the difference of the regulatory machinery under two culture system.

“…Однако из-за низкой буферности NFt системы в случае отключения работы насосов и необходимости дублирования их и дублирования источников электроэнергии, она не получила такого распространения как минеральная вата. Выращивание роз и хризантемы на циркулирующем питательном растворе позволяет существенно экономить энергию в расчёте на единицу продукции, за счёт возможности подогрева зоны корней в холодное время года [26,53]. В опытах, проведённых в Голландии, отмечено хорошее качество черенков хризантемы при их выращивании по методу DWC; аэрация водного потока повышала продуктивность растений на 10 % [39].…”
