| Chrysanthemum is the important cut flower after rose among the ornamental plants traded in the global flower market. It is propagated vegetatively and also has a strong sporophytic self-incompatibility system as shown by all members of Asteraceae family. Morphologically, the petal numbers and flower colours present maximum variation when compared to existing varieties. Twenty Inter Simple Sequence Repeat primers were used to detect the new variety of Chrysanthemum developed through spontaneous sporting. The results indicate that the rate of polymorphism showed significant differences as compared to other existing varieties. The average number of amplification products per primer was eight. The size of ISSR amplified fragments varied from 0.25 - 2.4 Kbp.... |

| Background: Analytical techniques such as methylation-sensitive amplification polymorphism and high-performance liquid chromatography were used to detect variation in DNA methylation of mature Chrysanthemum leaves during the floral transition induced by short-day (SD) treatment. Results: For both early- and late-flowering cultivars, the time from the date of planting to the appearance of the capitulum bud and early blooming were significantly shorter than those of the control. The capitulum development of the early-flowering cultivar was significantly accelerated compared to the control, unlike the late-flowering cultivar. The DNA methylation percentage of leaves was significantly altered during flower development. For the early-flowering cultivar, DNA... |

| En la presente investigación se estudió el efecto de la solución nutritiva universal de Steiner a diferentes concentraciones (12.5%, 25% y 37.5%) sobre la calidad comercial y vida de florero de crisantemo variedad Snow Eleonora; sobre el contenido de azúcares, tamaño de inflorescencias y pérdida de peso durante la vida de florero. Se consideraron 5 puntos de corte y se utilizó agua y solución preservativa. El testigo fue la forma de producción tradicional. La solución nutritiva Steiner diluida al 37.5% produjo las flores de mejor calidad comercial. La vida de florero fue la misma para los tratamientos con solución Steiner diluida (22 días); el testigo presentó la vida de florero más corta (13 días). Los puntos de corte 1 (50-80 mm), 2 (81-90 mm) y 3... |

| This study was conducted to evaluate the effect of polymer used with different nitrogen and potassium sources on the growth and nutrition of chrysanthemum (Dendranthema grandiforum, var. "Virginal") and on chemical characteristics of substrate. Two substrates were evaluated: 1) composite with 50 % organic soil, 45 % sand, and 5 % composted tobacco; 2) plow layer soil (0-20 cm depth; red oxisol typical dystrophic). The experimental design was a factorial (4x2x2) and included four polymer rates (0, 1, 2, and 4 g kg-1of substrate), two nitrogen ((NH4)2SO4 and (H2N)2CO), and two potassium (KCl and K2SO4) sources. Dry biomass, flower number, and concentration of K, Ca, and Mg were evaluated. Inverse relationships between polymer rates and plant biomass,... |

| Las micro, pequeñas y medianas empresas se constituyen como elementos importantes del desarrollo económico por lo que resulta importante ayudarlas a mejorar su posición tecnológica y la calidad de su producto para que incrementen su competitividad. El presente estudio se elaboró con el fin de evaluar la factibilidad de un proyecto de inversión en la producción de crisantemo (Chrysanthemum morifolium) para flor de corte en invernadero. El proyecto considera un incremento en los estándares de calidad del producto mediante la producción de la flor en un invernadero tipo cenital. El proyecto de inversión fue formulado para una micro empresa ubicada en Santa Catarina del Monte, Texcoco Edo. de México, localidad que cuenta con una larga tradición florícola. La... |

| Background Several MYB genes belonging to R2R3 MYB transcription factors have been used in several plant species to enhance anthocyanin production, and have shown various expression or regulation patterns. This study focused on the effect of ectopic expression of an RsMYB1 isolated from radish (Raphanus sativa) on chrysanthemum cv. Shinma'. Results The RT-PCR results confirmed that RsMYB1 regulated the expression of three key biosynthetic genes (CmF3H, CmDFR, and CmANS) that are responsible for anthocyanin production in transgenic chrysanthemum, but were not detected in the non-transgenic line. In all transgenic plants, higher expression levels of key biosynthetic genes were observed in flowers than in leaves. However, the presence of RsMYB1 in... |

| A solarização, durante dois meses, de um solo naturalmente infestado com Pythium, promoveu o controle do patógeno, de modo semelhante à aplicação de metalaxyl + mancozeb, na cultura de crisântemo. A incidência média de plantas mortas foi de 2,3% nas parcelas solarizadas; 1,0% no solo solarizado que recebeu metade da dose dos fungicidas; 9,0% com a aplicação da dose completa dos fungicidas (1 g de metalaxyl + 4,8 g de mancozeb/m²) e 38,9%, na testemunha não tratada. A solarização também promoveu o controle de plantas daninhas, avaliado através do peso da matéria seca das plantas emergentes aos 21 dias após o transplante das mudas, semelhantemente ao herbicida oxidiazon. |
