ABSTRACT Analyzes of plant growth throughout the crop vegetative cycle are important to know the dynamics of the plant development. Thus the objective of this work was to study the development of potato genotypes throughout the crop cycle, in three environments. Experiments were conducted in Canoinhas-SC, Pelotas-RS, and Brasília-DF, Brazil, in the 2018 crop season. A randomized complete block experimental design with three replicates was used. Traits related to different plant parts of clones F183-08-01 and F50-08-01 and the cv. Asterix were evaluated as a function of time and, at the end of the cycle, for tuber yield. The two clones were found to have high tuber yields, but later development than 'Asterix'; consequently, its management must be adapted to this trait. Leaf mass, leaf number, leaf area index and root mass plus stems were correlated with each other, and leaf area index, leaf number and leaf mass can be quantified through only one of these traits, due to the high correlation between them. There were also positive and significant correlations between the height of the tallest stem and the root plus stem mass and the tuber mass, indicating that more vigorous plants have higher tuber yield.

RESUMO O conhecimento do padrão de crescimento da planta em condições climáticas específicas (curva de crescimento) é a base para explorar o potencial máximo de rendimento de genótipos de batata. Objetivou-se estabelecer a curva de crescimento e avaliar as características agronômicas, produtividade e gravidade específica de tubérculos de três cultivares e um clone elite, a fim de fornecer informações básicas sobre as características produtivas desses genótipos no Centro-Oeste brasileiro. Utilizou-se delineamento experimental de blocos ao acaso, com 3 repetições. A massa seca acumulada pelos tubérculos variou de 6,28 (Agata) a 9,75 t ha-1 [F183-08-01(F183)]; a massa total de tubérculos de 35,33 (BRSIPR Bel) a 58,60 t ha-1 (F183); a massa de tubérculos comercializáveis de 23,46 (Asterix) a 48,24 t ha-1 (F183); e o índice de área foliar de 2,86 (Agata) a 10,60 (F183). F183 apresentou boa adaptação às condições de cultivo do Distrito Federal, sendo fortemente recomendado para essa região.

ABSTRACT The knowledge of the plant growth pattern under specific climatic conditions (growth curve) is the basis for exploiting the maximum yield potential of potato genotypes. This study aimed to establish the growth curve, as well as to evaluate the agronomic characteristics, yield and specific gravity of tubers of three potato cultivars and one elite clone, thus providing basic information on the productive characteristics of these genotypes in the Brazilian Midwest. A randomized experimental block design, with three replications, was used. The dry mass accumulated by the tubers varied from 6.28 (Agata) to 9.75 t ha-1 [F183-08-01 (F183)]; the total mass of tubers from 35.33 (BRSIPR Bel) to 58.60 t ha-1 (F183); the mass of marketable tubers from 23.46 (Asterix) to 48.24 t ha-1 (F183); and the leaf area index from 2.86 (Agata) to 10.60 (F183). F183 showed a good adaptation to the cultivation conditions of the Federal District, being strongly recommended for this region.

RESUMO O conhecimento das demandas nutricionais dos diferentes genótipos de batata é necessário para o desenvolvimento de recomendações de fertilização. Objetivou-se determinar e comparar as curvas de acúmulo de macronutrientes nos genótipos de batata Agata, Asterix, BRSIPR Bel e F183-08-01, visando subsidiar o parcelamento de adubação que atenda as demandas específicas de cada genótipo. O delineamento foi em blocos casualizados, com os tratamentos (genótipos × estádios de planta) dispostos em esquema de parcelas subdivididas, com três repetições. Os genótipos foram cultivados em parcelas contendo 75 plantas cada. As subparcelas dentro de uma parcela continham quatro plantas cada e corresponderam ao número de dias após o plantio, quando amostras destrutivas de plantas inteiras foram coletadas. As plantas das subparcelas foram colhidas aos 24, 38, 52, 66 e 80 dias após o plantio, para estimar a massa seca acumulada por diferentes partes da planta (parte aérea + raízes, tubérculos e plantas inteiras) e para determinar as curvas de acúmulo de macronutrientes. F183-08-01 apresentou o maior acúmulo total de N, Ca, Mg e S (141,37; 29,21; 25,16; e 22,36 kg ha-1, respectivamente). As maiores taxas de acúmulo de macronutrientes para todos os genótipos de batata ocorreram aos 24 dias após o plantio, coincidindo com o início da formação dos tubérculos.

ABSTRACT Knowledge on the nutritional demands of different potato genotypes is necessary for the development of fertilizing recommendations. This study aimed to determine and compare the macronutrient accumulation curves in the Agata, Asterix, BRSIPR Bel and F183-08-01 potato genotypes, in order to subsidize the split fertilization that could meet the specific demands of each genotype. A randomized block design was used, with the treatments (genotypes × plant stages) arranged in a split-plot scheme, with three replications. The genotypes were grown in plots containing 75 plants each. The subplots within a plot contained four plants each and corresponded to the number of days after planting, when destructive samples of whole plants were collected. The plants from the subplots were harvested at 24, 38, 52, 66 and 80 days after planting, to estimate the dry mass accumulated by different parts of the plant (shoots + roots, tubers and whole plants), as well as to determine the macronutrient accumulation curves. F183-08-01 presented the highest total accumulation of N, Ca, Mg and S (141.37, 29.21, 25.16 and 22.36 kg ha-1, respectively). The highest rates of macronutrient accumulation for all the potato genotypes occurred at 24 days after planting, coinciding with the beginning of the tubers formation.

ABSTRACTThe genus Sinningia belongs to the Neotropical tribe Gesnerieae, subtribe Ligeriinae, presently consisting of only three genera, Paliavana, Sinnigiaand Vanhouttea. These genera were separated from a larger concept of tribe Gloxinieae based on phylogenetic studies with molecular data. In Rio Grande do Sul, southern Brazil, 12 species and one natural hybrid of Sinningiahave been recorded. Species of Sinningia in this area are erect or ascending herbs or subshrubs arising from underground or partially exposed tubers. They grow in very distinct ecological conditions, from water-saturated marshes to dry grasslands or shrublands, but most often in rupicolous or epiphytic habitats commonly associated with forest environments. In this review we provide an identification key to the species level and morphological descriptions and illustrations, comments on taxonomic aspects, distributional maps and IUCN Red List Categories and Criteria for all twelve species. Additionally, we designate lectotypes for S. allagophylla and S. sellovii and consider the recently described S. lutea as a synonym of the highly variable S. allagophylla.

Objetivo: Avaliar a influência de um programa de reabilitação domiciliar para portadores de dor lombar crônica por meio da avaliação de força muscular abdominal, mobilidade lombar, atividades diárias e melhora dos níveis de dor. Um objetivo secundário foi avaliar a adesão dos participantes a este programa. Métodos: Foram avaliados 99 pacientes divididos em grupo caso (69 pacientes com lombalgia crônica, sem indicação de tratamento cirúrgico) e grupo controle (30 pacientes sem lombalgia), medindo-se os seguintes parâmetros: 1) mobilidade lombar, 2) resistência da musculatura abdominal, 3) dor pela escala visual analógica de dor (EVA), 4) limitação nas atividades diárias (escala de Oswestry). Os pacientes receberam orientação individualizada sobre os exercícios domiciliares, a serem realizados por dois meses. Para a comparação dos grupos "controle" e "caso" foi aplicado o teste não paramétrico de Mann Whitney. Para comparação dos tempos "antes" e "depois" no grupo de pacientes que retornaram, foi aplicado o teste não paramétrico de Wilcoxon. Resultados: Dos 69 pacientes que aceitaram participar, 30 concluíram os exercícios orientados no período de dois meses e retornaram para avaliação final. Na avaliação inicial, observou-se diferença significativa (p < 0,05) entre os grupos caso e controle para mobilidade lombar e resistência abdominal. No grupo caso, houve melhora significativa em todos os quesitos avaliados ao término do programa de exercícios. Conclusão: O programa de exercícios domiciliar foi eficaz como opção terapêutica para dor lombar. A adesão ao tratamento foi baixa, sendo este seu principal fator limitante.

Objective: To evaluate the results of a home rehabilitation program for patients with chronic low back pain through the evaluation of abdominal muscle strength, lumbar mobility, daily activities and improved levels of pain. A secondary objective was to evaluate the adherence of the participants to this program. Methods: We evaluated 99 patients divided into case group (69 patients with chronic low back pain without indication for surgical treatment) and control group (30 patients without low back pain), the following parameters being measured: 1) lumbar mobility, 2) strength of the abdominal muscles, 3) pain by visual analog scale (VAS), 4) limitation in daily activities (Oswestry scale). Patients received individualized guidance on home exercises to be performed during two months. For comparison of groups "control" and "case" the nonparametric Mann Whitney test was applied. For comparison of the times "before" and "after" in the group of patients who returned, the nonparametric Wilcoxon test was applied. Results: Of the 69 patients who agreed to participate, 30 completed the targeted exercises within two months and returned for the final evaluation. At baseline, there was a significant difference (p<0.05) between the case and control groups for lumbar mobility and abdominal strength. In the case group there was significant improvement in all aspects evaluated at the end of the exercise program. Conclusion: The home rehabilitation program was effective as a treatment option for low back pain. Treatment adherence was low, this being the main limiting factor.

Objetivo: Evaluar la influencia de un programa de rehabilitación domiciliaria para pacientes con lumbalgia através de la evaluación de la fuerza muscular abdominal, la movilidad lumbar, las actividades diarias y la mejoría de los niveles del dolor. Un objetivo secundario fue evaluar la adherencia de los participantes en este programa. Métodos: Se evaluaron 99 pacientes divididos en grupo caso (69 pacientes con lumbalgia crónica) y grupo control (30 pacientes sin lumbalgia), mediante la medición de los siguientes parámetros: 1) movilidad lumbar, 2) fuerza de la musculatura abdominal, 3) dolor mediante la escala visual análoga de dolor (EVA), 4) limitación en las actividades diarias (escala de Oswestry). Los pacientes recibieron orientación individualizada sobre ejercicios domiciliarios, para llevarse a cabo por dos meses. Para la comparación de los grupos "control" y "caso" se aplicó la prueba no paramétrica de Mann Whitney. Para la comparación de los tiempos "antes" y "después" en el grupo de pacientes que regresaron, se aplicó la prueba no paramétrica de Wilcoxon. Resultados: De los 69 pacientes que aceptaron participar, 30 completaron los ejercicios específicos en el plazo de dos meses y regresaron para la evaluación final. En la evaluación del inicio del estudio, no hubo diferencias significativas (p < 0,05) entre los grupos caso y control para la movilidad lumbar y la fuerza abdominal. En el grupo caso se observó una mejoría significativa en todas las variables evaluadas al final del programa de ejercicios. Conclusión: El programa de ejercicios domiciliarios fue eficaz como una opción terapéutica para el tratamiento del dolor lumbar. La adherencia al tratamiento fue baja, siendo este su principal factor limitante.
