Abstract:
The correlations among different media, mineral nutrition and morphological features of gerbera flowers in relation to their vase-life period investigated. The bast medium for longevity of cut gerbera flowers was the mixture of composted pine bark and peat moss fertilized with N – 250 mg/1 and Mg – 150 mg/1. It was found that cut gerberas lasted longer when they were the Alkemade type, i.e. with wide petals. Yellow flowers remained fresh longer than red and pink ones. It was also found that the vase-life period of gerberas directly correlated with the length of floral stalk, its ability to grow and the inflorescence diameter. The solution of flower preservative Proflovit-72 was effective 'in extending life at room temperature and improved the quality and longevity of flowers which were previously in coldstorage for 1 to 3 weeks.

Abstract:
Micropropagation techniques changed the production of clonal plantlets in the world. However, the high costs of micropropagated plantlets continue as the main constraint for the expansion of the technique. This paper aimed to test the use of the chemical sterilization of culture medium using chlorine dioxide (ClO2) for in vitro cultivation of gerbera. There was used gerbera in vitro shoots in the stage of rooting for these experiments, using 0.0035%, 0.0070% and 0.0105% of chlorine dioxide in the culture medium. Also, peracetic acid was tested previously for sterilization, but resulted in microbial contamination. Chemical sterilization of the culture medium was successfully using ClO2 at 0.0035% to 0.0105% (100% decontamination) at rooting and elongation stage of gerbera with production of plantlets with similar (number of leaves, total and root fresh weight) or higher quality (mainly aerial part) at rooting/elongation stage, compared with autoclaved culture medium. The increase of concentration of ClO2 also resulted in increasing of height and fresh weight of aerial part of gerberas. The ClO2 could replace the autoclaving with production of sterilized culture medium without phytotoxic problems to gerbera in vitro cultivation.

Abstract:
Gerbera is used as a cut flower and has gained popularity as ornamental flower and great demand in the world market for ornamental plants. Micropropagation is used to meet the demand for commercial planting material. The objective was to evaluate the BAP and ANA phytoregulators effect gerberas in vitro multiplication. The explants were inoculated in MS culture medium containing different concentrations of BAP (0.0; 2.22; 4.44; 8.88 and 17.76 µmol L-1) and ANA (0.0; 1.34; 2.68 and 5.36 µmol L-1). After eight weeks, the number of shoots formed in each explant and the average length of the shoots were evaluated. Was possible to establish and recommend an ideal concentration of BAP and ANA for each gerbera genotype.

Abstract:
The aim of this work was to propose a methodology for commercial classification of gerbera´s capitulum based on the trans flowers overlap coefficient. Three to eight capitula of twenty-eight cultivars of gerbera cut flower and seven non-commercial accesses were used. The width measurement of the trans flowers group (internal ray flower) as well as the sum of the width of the trans and ray flowers (external ray flower) groups were taken from each capitulum. The average of each access and the overlap coefficient were calculated (CS = width of the trans flowers group / Σ of the width of the trans and ray flowers groups) and submitted to the multivariate analysis, to verify the grouping by the average Euclidian distance matrix. It is proposed that gerberas with CS= 0.01 to 0.15 be classified as simple, CS= 0.16 to 0.40 as semi-double and CS superior to 0.41 as double. The overlap coefficient (CS) can be used to systematize the classification of the gerbera capitula, reducing the divergences in the classification and the subjectivity in the decisions of producers, florists and breeders.

Abstract:
Gerbera hybrida (sädelatva) on suosittu koristekasvi. Terälehtien värit ovat peräisin vesiliukoisistaantosyaaneista, jotka ovat sekundäärimetabolian tuotteita. Tutkiessamme tätä metaboliareittiä, löysimmesen läheltä haaran, joka johtaa karvaan makuisiin yhdisteisiin, gerberiiniin ja parasorbosidiin.Näiden karvasaineiden merkitys gerberalle on ollut tuntematon.Gerberan karvasaineiden biosynteesiin vaikutettiin geenitekniikan keinoin hiljentämällä keskeisen2PS-geenin toiminta. Anti-2PS-linjojen siirtogeenisiin gerberoihin ei gerberiiniä ja parasorbosidiasynny, vaan ne maistuvat tavanomaiseen gerberaan verrattuna makealta. Epäily näiden makealta maistuvienkasvien herkkyydestä hyönteisherbivoriaan heräsi kasvihuonehavaintojemme perusteella.Teimme erilaisia syöttö- ja munintakokeita, joissa hyönteiset saivat valita karvasaineettoman jakarvasainetta sisältävän gerberan välillä. Karvasaineilla oli voimakas estävä vaikutus täplätupsukkaan(Orgyia antiqua) ja krysanteemiyökkösen (Spodoptera littoralis) herbivoriaa vastaan. Ansarijauhiasen(Trialeurodes vaporariorum) toukille karvasaineilla ei ollut merkitystä.Tutkimuksemme perusteella karvasaineilla on hyönteisherbivoriaa ehkäisevä vaikutus. Eri lajikkeillaon vaihtelua karvasaineiden määrän suhteen ja yhdisteiden pitoisuuksien mittaaminen onyksinkertainen keino uusien lajikkeiden hyönteiskestävyyden arvioimiseen jalostustyössä.

Abstract:
Recently the Asian Gerbera species were shown to form a clade that was not the sister group of the African Gerbera. In this study, the position of the Asian Gerbera species was further assessed based on morphology and molecular phylogenetic analyses that included six Asian Gerbera and 26 other species from the Gerbera-complex. Morphological results showed that the six Asian Gerbera species, which were sampled, bear leaves with the adaxial epidermal surface lacking stomates, possess bracteate scapes and lack inner ray florets. These characters suggest that the Asian Gerbera species are most closely related to the species of Uechtritzia, which also share similar pollen grain size and shape with the Asian Gerbera, rather than to the African Gerbera. Furthermore, the phylogenetic results based on two nuclear (ITS and ETS) and three chloroplast (trnL–trnF, trnL–rpl32 and trnC–petN) sequences strongly support the Asian Gerbera and Uechtritzia forming a clade, with the latter nested within the Asian Gerbera species. Both morphological and molecular phylogenetic data thus confirmed the taxonomic identity of the Asian Gerbera and Uechtritzia. The authors herein formally treat the nine species of the Asian Gerbera and the three species of Uechtritzia as members of the genus Oreoseris, which is the earliest generic name of this lineage and has the nomenclatural priority.

Abstract:
La producción de ornamentales a nivel nacional es de 23,000 ha., con un total de 25,000 productores que representan un valor de producción de 6100 millones de pesos. Solo el 5% se exporta. (SNICS, 2014). Uno de los cultivos ornamentales más importantes es la gerbera (Gerbera x hibrida) perteneciente a la familia Asteraceae. Es una planta herbácea, vivaz, en roseta, cuyo cultivo puede durar varios años, según cultivares y técnicas de manejo empleadas (Villaseñor, 2004). Las variedades comerciales proceden de hibridaciones con especies (Gerbera jamesonii y G. viridifolia), del sur de África, donde el clima es tropical de montaña (Nesom, 2004). El mejoramiento genético de la gerbera comenzó a finales del siglo IXX, en Cambridge Inglaterra, cuando Richard Lynch, cruzó G. jamesonii con G. viridifolia. Las variedades comerciales recientes fueron originadas en este cruzamiento y se denominan híbridos de G. jamesonii dado que la principal contribución genética fue aportada por dicha especie (Sobral, 1996). Existen miles de cultivares que varían mucho en forma, tamaño y colores: blanco, amarillo, naranja, rojo, rosa. El centro de la flor es negro, purpura o verde. Frecuentemente la misma flor puede tener lígulas de varios colores (Jaimez, et al., 2011). La gerbera es la quinta especie más usada como "flor de corte" en el mundo, después de la rosa (rosa spp.), clavel (Dianthus caryophyllus), crisantemo (Chrysanthemum spp.), y tulipán (Tulipa spp. L.), de ahí su importancia económica. Los colores más demandados son rosa (incluye tonos fucsia, 40 %), rojo (20 %), amarillo (10 %), blanco (10 %), naranja (10 %) y otros. En función del tipo de inflorescencia, el consumidor prefiere el 20-40 % para las flores dobles, 20-40 % para las semidobles y del 30-60 % para las sencillas. Respecto 2 al color de la parte central de la inflorescencia, la demanda es del 20-30 % para las flores de disco negro y del 70-80 % para las de centro verde (Info Rural, 2012; Gómez, 2010). En cuanto a los parámetros de calidad que sirven para la clasificación de la flor, existen diversos criterios, aunque los más empleados son la longitud del tallo, diámetro del capítulo, color de la inflorescencia, rendimiento y durabilidad de poscosecha (Bañon, 1993).

Abstract:
La gerbera es una de las flores ornamentales más importantes comercializadas a nivel mundial. La información sobre la variabilidad morfológica y molecular de esta especie representa un recurso importante para los programas de mejora que se basan en la selección de genotipos prometedores. El objetivo del presente estudio fue caracterizar morfológica y molecularmente 24 híbridos de gerbera (Gerbera hybrida). El análisis morfológico se basó en 52 caracteres de la UPOV, 9 cuantitativos y 43 cualitativos mediante análisis multivariado. En la caracterización molecular, el ADN se extrajo con el método CTAB y en la ampliación se utilizaron 11 cebadores RAPD´s cuyos productos se analizaron con el método de agrupación Neighbour Joining, índice de similitud Dice y remuestreo de 1,000 corridas que permitieron establecer las relaciones moleculares entre las muestras. El análisis morfológico de los rasgos cualitativos dispuso a los genotipos en cinco grupos. Las variables de mayor valor discriminatorio para los híbridos de gerbera fueron: diámetro de disco, ancho y longitud de flor, altura de involucro, diámetro de disco diámetro de capítulo y longitud de pedúnculo. En el análisis molecular, los valores PIC promedio fueron 0.43, que cataloga a los cebadores como altamente informativos, con los cavadores OPA8 y OPA19 con la mayor capacidad discriminante. Los resultados obtenidos en este trabajo permitieron diferenciar la totalidad de los genotipos analizados, pudiéndose inferir un alto grado de variabilidad en la población bajo estudio, mostrando que los RAPD´s constituyen una herramienta molecular eficaz cuando se requiera una manipulación simple, confiable y de bajo costo.

Gerbera, from South Africa, belongs to Asteraceae family. They are herbaceous with flowers grouped in a head inflorescence. They are very popular and used as decorative garden plant, cut flowers and as experimental organism. São Paulo state leads the market of Brazilian ornamental flowers. Among the species produced by Brazilian companies, Gerbera is one of the very well accepted into the market. In the beginning XXth century micro propagation calls the attention of scientists; the pioneer was Haberlandt in 1902 with somatic cells. The studies on tissue culture, in Brazil, started at the 50´s in São Paulo Biological Institute. The chemical control of the differentiation of the aerial part was observed in culture of tobacco callus. This was the observation that the in vitro organogenesis process is controlled by hormonal substances that control the development in canopy, root or callus depending on the balance between auxins and cytokines. Some substances, even when in small amounts, delay or inhibit the substratum oxidation and can act at different levels on the oxidative sequence, these substances are called antioxidants. The living organisms possess natural scavenging mechanisms, enzymatically or not, of free radicals, not allowing their transformation in more toxic products for the cells. The enzyme superoxide dismutase, together with others is the main antioxidant defences that act in eukaryotic organisms.
As Gerberas são oriundas da África do Sul, pertencem à família Asteraceae e são herbáceas dotadas de flores em capítulos. São muito populares e utilizadas como planta decorativa de exterior, flores de corte e como organismo de experimentos. O estado de São Paulo lidera o mercado de flores ornamentais no Brasil. Dentre as várias espécies produzidas pelas empresas brasileiras, a Gerbera está inclusa com boa aceitação no mercado. No início do século XX a micropropagação chama a atenção de estudiosos, o pioneiro nesta área foi Haberlandt em 1902 com células de tecidos somáticos. No Brasil os estudos sobre cultura de tecidos começam na década de 50 em São Paulo no Instituto Biológico. O controle químico da diferenciação da parte aérea foi observado em cultura de calo de tabaco. Esta foi à constatação de que o processo de organogênese in vitro é controlado por substâncias hormonais sendo que o desenvolvimento de parte aérea, raiz ou calo é determinado pelo balanço entre auxinas e citocininas. Existem substâncias que, quando presentes em pequenas quantidades, retardam ou inibem a oxidação de substratos e podem agir em diferentes níveis da seqüência oxidativa, estas substâncias são denominadas antioxidantes. Os organismos vivos possuem mecanismos naturais de eliminação de radicais livres por intermédio de enzimas ou não, impedindo sua transformação em produtos mais tóxicos para as células. A enzima denominada superóxido dismutase, junto com outras são as principais defesas antioxidantes que atuam nos organismos superiores.

Abstract:
El cultivo de gerbera (Gerbera hybrida) en el sur del Estado de México es de importancia económica, sin embargo, es afectado en rendimiento y calidad por la mosca blanca, Trialeurodes vaporariorum Westwood, 1856. El objetivo del presente estudio fue comparar la variación morfológica de hojas y color de lígulas exteriores del capítulo floral de 10 genotipos de G. hybrida y su relación con la incidencia de T. vaporariorum. La investigación se realizó en los invernaderos del Centro Universitario UAEM Tenancingo, en el Estado de México. El diseño experimental fue de bloques completos al azar con 10 repeticiones. La infestación del insecto fue natural al inicio de la emisión del capítulo floral. A los 30 (Inicio de emisión de pedúnculo floral) y 55 (floración a punto de corte) días después de la infestación se contabilizaron ninfas al centro del envés de la hoja en 1 cm2 y el número de adultos por hoja; también se midió el número, largo, ancho, pubescencia y profundidad de incisión en tercio central del envés de las hojas y el color de lígulas exteriores del capítulo floral. Los resultados mostraron diferencias altamente significativas (P≤0.01) entre genotipos en la incidencia del insecto y el número, largo, ancho, pubescencia y profundidad de incisión en tercio central del envés de las hojas. El ancho de la hoja se correlacionó positivamente con el total de insectos (ninfas + adultos) (r=0.77, p≤0.05) y con adultos (r = 0.81, p≤0.05), también la profundidad de incisión de la hoja se correlaciono positivamente (r= 0.56, p≤0.05) con el total de insectos (ninfas + adultos); pero no hubo correlación de la incidencia con la pubescencia denotada por el número de tricomas. El color de la lígula no fue específico para la incidencia del insecto, lo que indicó que en ninguno de los colores de los genotipos analizados, rosa, blanco, amarillo y rojo, fue de preferencia particular para la mosca blanca. Los resultados indicaron amplia variación entre los genotipos en la incidencia de mosca blanca y también variación morfológica de las variables evaluadas entre genotipos, donde el tamaño de la hoja influye en una mayor incidencia del insecto.

Abstract:
Nous avons aborde l'amelioration de gerbera jamesonii pour la potee par deux voies: la realisation de croisements et la connaissance des besoins ecophysiologiques de l'espece. Les tentatives de croisements intergeneriques nous ont permis d'obtenir des plantes de phenotype crispe dont l'origine a ete difficile a determiner. Nous nous sommes attaches a la ealisation de croisements interspecifiques avec gerbera kunzeana. C'est une espece originaire du nepal, de petite taille, tres florifere et possedant des capitules fermes. L'etude de sa cleistogamie a permis de mettre en evidence, par comparaison avec gerbera jamesonii, espece chasmogame, une reduction de la taille des capitules et des fleurons, un cycle de reproduction plus court, un nombre inferieur de grains de pollen presents pour obtenir un akene; caracteres classiques de la cleistogamie. En revanche, les grains de pollen commencent leur germination sur le stigmate et non dans les antheres ce qui est plus rare. Nous pensons que gerbera kunzeana est une espece a cleistogamie complete d'origine genetique. Le croisement gerbera kunzeanagerbera jamesonii a ete realise. La plante hybride b3-5 presente un phenotype intermediaire entre les deux parents, des capitules ouverts a ligules pigmentees. De grandes irregularites ont ete decelees au niveau de la formation du pollen au stade tetrade. Notre propos etant d'obtenir des gerberas de petite taille, nous avons mis en evidence l'importance de la duree d'eclairement appliquee aux plantes: contrairement aux resultats obtenus en jours longs (16 h), la culture en jours courts (9 h) d'une variete de gerbera jamesonii actuellement commercialisee permet d'obtenir des plantes significativement plus compactes a 22#oc ou 20#oc-15#oc

Abstract:
Gerbera, a member of the Asteraceae family, has approximately 30 species known in nature. It has spread naturally in South Africa, Africa, Madagascar, and tropical Asia. The first scientific description of gerberas is J.D. Described by Hooker. It is also known as the Transvaal Daisy or Barberton Daisy. It is the second most produced cut flower after carnation as cut flower in our country. We can divide the scientific studies conducted on the gerbera plant into four groups. Studies in general; To produce 1st quality gerbera by providing the growth of plant height, flower diameter and flower stem with growth regulators, to obtain fast and many plants with tissue culture, to bring new products to the product range with breeding studies and to maintain the vitality of the plant in the process from harvest to consumer It is based on increasing the life of the vase and introducing new solutions to the market. This study was conducted to emphasize the importance of Gerbera as a cut flower and its developments in scientific research.

Abstract:
Comparing Narrow- vs. Broad-Spectrum Antibiotics for Common Infections in Children. The choice of antibiotic to treat acute bacterial upper respiratory tract infections in children can affect both symptom resolution and the risk of side effects such as diarrhea and vomiting. The findings of a PCORI-funded study published in JAMA can help clinicians treating children for acute respiratory tract infections (ARTIs)—including acute otitis media, Group A streptococcal pharyngitis, and acute sinusitis—make decisions with parents about the medicine that is best for the child. The study, led by Jeffrey Gerber, a pediatrician and researcher at the Children’s Hospital of Philadelphia, included 30,086 children ages 6 months to 12 years taking narrow- and broad-spectrum antibiotics to treat ARTIs.
