RESUMO O objetivo deste trabalho foi avaliar a influência da poda da haste principal de plantas de calêndula na produção de capítulos florais. O experimento foi conduzido em blocos casualizados, com cinco repetições. Foram estudados os seguintes estágios de supressão da haste principal: testemunha (sem poda), acima de 10 folhas, acima de 15 folhas e botão floral visível; também foram avaliadas três épocas de colheita: julho, agosto e setembro, constituindo o arranjo do experimento em esquema fatorial 4x3. Foram avaliados o diâmetro, o número, e a massa de matéria fresca e seca de capítulos. Houve efeito significativo da poda da haste principal na matéria fresca e seca de capítulos, quando realizada no momento em que a planta possui mais de 15 folhas e apresenta botão floral visível. A colheita no mês de setembro caracterizou-se como a mais adequada, pois apresentou o maior diâmetro, número, e massa de matéria fresca e seca de capítulos florais.

ABSTRACT The purpose of this work was to evaluate the influence of cutting the apex of the main stem of marigold plants on floral capitula yield. The experiment was carried out in a randomized complete block design, with five replicates. The following removal stages of the main stem apexes were studied: control (without pruning), up to 10 leaves, up to 15 leaves and visible flower bud. Three harvest periods were also evaluated: July, August and September, composing a factorial experiment in a 4x3 arrangement. The diameter, number, fresh matter and the dry capitula were evaluated. The most significant effect of cutting the apex of the main stem on fresh and dry matter of the capitula was obtained when the technique was performed at the time the plants had up to 15 leaves and visible flower bud. The harvesting performed in September showed to be the most promising, since it presented the larger diameter, higher number and higher fresh matter and the dry capitula.

RESUMO O objetivo neste trabalho foi avaliar a consorciação entre alface (Veneranda) e cebola (Baia Periforme) em diferentes espaçamentos entre linhas de cultivo. O experimento foi conduzido em delineamento blocos casualizados com quatro repetições. Foram estudadas formas de cultivo (monocultivo e consórcio de alface e cebola) e espaçamentos entre linhas (20, 35 e 50 cm), no esquema fatorial 3x3. Foram avaliados o diâmetro, massa fresca da parte aérea e número de folhas da alface. Para a cebola foram avaliadas a massa fresca e o diâmetro de bulbos. A forma de cultivo solteiro ou consorciado não afetou o desenvolvimento da alface. Porém, o diâmetro, massa fresca da parte aérea e o número de folhas foram superiores no espaçamento de 20 cm entre linhas. O diâmetro e massa fresca de bulbos de cebola quando consorciados com a alface não apresentaram diferença nos espaçamentos testados. As plantas foram beneficiadas no sistema consorciado quando cultivadas nos espaçamentos de 20 e 35 cm entre linhas de cultivo.

ABSTRACT The objective was to evaluate the intercropping of lettuce (Veneranda) and onion (Baia Periforme) under different spacings between cultivation lines. The research was carried out in a randomized block design with four replications. Forms of cultivation were studied (monoculture and intercropping of lettuce and onions) and row spacing (20, 35 and 50 cm) in a 3x3 factorial scheme. Diameter, fresh weight of the aboveground part and number of lettuce leaves were evaluated. For onion, fresh mass and bulb diameter were evaluated. The form of cultivation, single or intercropped, did not affect the development of lettuce. However, diameter, fresh weight of the aboveground part and number of leaves were higher under the 20 cm spacing between rows. Diameter and fresh weight of onion bulbs when intercropped with lettuce showed no difference in the tested spacings. Plants benefited from the intercropping system when grown under 20 and 35 cm between cultivation lines.

Abstract BACKGROUND: Vitiligo, although asymptomatic, highly compromises patients' quality of life (QoL). Therefore, an adequate evaluation of QoL is essential. OBJECTIVES: Translation, cultural adaptation and validation of VitiQol (Vitiligo-specific health-related quality of life instrument) into Brazilian Portuguese. METHODS: The study was conducted in two stages; the first stage was the translation and cultural/linguistic adaptation of the instrument; the second stage was the instrument's validation. RESULTS: The translated VitiQol showed high internal consistency (Cronbach alpha = 0.944) and high test-retest reliability and intraclass correlation coefficient=0.95 (CI 95% 0.86 - 0.98), p<0.001. There was no statistically significant difference between the means of the first completion of the VitiQoL questionnaire and the retest, p = 0.661. There was a significant correlation between VitiQoL and DLQI (r = 0.776, p <0.001) and also between VitiQoL-PB and subjects' assessment of the severity of their disease (r = 0.702, p <0.001). CONCLUSIONS: The impact of vitiligo on the QoL of Brazilian patients can be assessed by a specific questionnaire.
