“…Theoretically, chemical ripeners (popularly called plant growth regulators) are synthetic products that act as plant hormones, applied to crops for improve its quality and, consequently, supply add-value feedstocks to the industrial processing. Nationally, glyphosate, methyl-sulfumeturon-methyl, ethephon, and ethyl-trinexapac, are the commonly tested main products at sugarcane tillages and, for this reason, there are little scientific information about the its benefits to sweet sorghum crop (Han et al, 2011;Meschede et al, 2011;Heerden et al, 2012;Viana et al, 2015;Muhwiridzwa et al, 2016;Viana et al, 2016).…”

- There is a little information about sweet sorghum crop behavior under chemical ripeners spraying management. Therefore, the aim of this study was to assess the technological profile of sweet sorghum (cv. CMSXS-646) juice under spraying of plant growth regulators and sampling periods. A randomized complete block experimental factorial design was used, with an additional control treatment (arrangement 2x2+1), corresponding to two chemical ripeners with three-doses for each product, glyphosate (0.2, 0.4, and 0.8 l c.p. ha-1) and methyl-sulfumeturon (10, 20, and 30 g c.p. ha-1), two sampling periods (15 and 30-days after spraying - DAS) and one control treatment (water spraying). After crop harvest, stalks were milled using a hydraulic press and the derived juice was assessed for total soluble solids (°Brix), apparent sucrose (POL), purity (PRT), reducing sugars (RS), total reducing sugars (TRS), fibers (FIB) and recoverable theoretical sugars (RTS). The dataset was subjected to the Shapiro-Wilk, Fisher, Tukey, Pearson and multiple linear regression statistical tests (p<0.05). There was an interaction between causes of variation for almost all assessed characteristics except to RTS, only affected by the sampling period. As conclusion, it is possible to grow sweet sorghum (cv. CMSXS-646) till thirty-days after spraying of chemical ripeners, treated by glyphosate 0.4 l c.p. ha-1 or sulfumeturon-methyl 10 g c.p. ha-1, because these doses caused feedstock with high °Brix, POL, total reducing sugars, purity levels.Keywords: Sorghum spp., phytorregulators, plant growth regulators, glyphosate, sulfumeturon-methyl. PERFIL TECNOLÓGICO DE CALDO DE SORGO SACARINO (cv. CMSXS-646) SUBMETIDO À APLICAÇÃO DE MATURADORES QUÍMICOS E ÉPOCAS DE AMOSTRAGEMRESUMO – Há poucas informações sobre o comportamento da cultura do sorgo sacarino sob manejo de aplicação de maturadores químicos. Portanto, o objetivo desta pesquisa foi avaliar o perfil tecnológico de caldo de sorgo sacarino cv. CMSXS-646 submetido à aplicação de maturadores químicos e períodos de amostragem. Aplicou-se o delineamento de blocos inteiramente casualizados, em esquema de fatorial (2x2+1), correspondente a dois maturadores químicos com três dosagens - glifosato (0,2; 0,4 e 0,8 l p.c. ha-1) e sulfumeturon-metil (10, 20 e 30 g p.c. ha-1); dois períodos de amostragem (15 e 30 dias após aplicação - DAA); e um tratamento controle (aplicação de água). Após a colheita, destinaram-se colmos à moagem, realizada em prensa hidráulica, para extração de caldo; avaliaram-se sólidos solúveis totais (°Brix), sacarose aparente (POL), pureza (PRT), açúcares redutores (AR), açúcares redutores totais (ART), fibras (FIB) e açúcares teóricos recuperáveis (ATR). Ao conjunto de dados, aplicaram-se testes estatísticos, Shapiro- Wilk, Fisher, Tukey, Pearson e regressão múltipla, ao nível de 5% de probabilidade. Houve interação entre as causas de variação para quase todas as características, exceto ATR, influenciado, somente, pelo período de amostragem. Concluiu-se que a aplicação dos maturadores químicos glifosato 0,4 l c.p. ha-1 e sulfumeturon-metil 10 g p.c. ha-1 apresentou um incremento na qualidade da matéria-prima com alto teor de °Brix, POL, açúcares redutores totais e níveis de pureza trinta dias após a pulverização dos maturadores.Palavras-chave: Sorghum spp., fitorreguladores, reguladores de crescimento vegetal,

R. A.;* Viana, R. S.; Manarelli, F.; Viana, C. R. A.; Nakamune, A. C. M. S.Abstract: The aim of this study was to evaluate juice technological traits and antioxidant enzymes specific activities from sugarcane cultivars following chemical ripeners spraying. The field experiment had a randomized block design (with six replicates) in factorial arrangment (9x2): active ingredients (control 0.00 L ha -1 , ethephon 0.67 L ha -1 , glyphosate 0.35 L ha -1 , MTD 1.00 L ha -1 , trinexapacethyl 0.80 L ha -1 , sulfumeturon-methyl 0.02 kg ha -1 , ethephon 0.34 L ha -1 plus glyphosate 0.15 L ha -1 , MTD 1.00 L ha -1 plus glyphosate 0.15 L ha -1 , and sulfumeturon-methyl 0,02 kg ha -1 plus glyphosate 0.15 L ha -1 ), and sugarcane cultivars (RB86-5156 and RB86-5453), respectively. Subsequent to crop harvest (carried out 60-days after chemical ripeners spraying) stalks and leaf samples were assessed to °Brix, Pol, purity, theoretical sugars recoverable (TSR), fibers, superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and peroxidase (POD) specific activities. There was null hypothesis rejection at interactive level between causes of variation for CAT and POD; while SOD, PAX, and all juice traits were affected only at simple effects level. It was concluded that chemical ripeners management enhanced juice quality and antioxidant enzymatic system reactivity of sugarcane crop. ResumoO objetivo desta pesquisa foi avaliar parâmetros tecnológicos de caldo e atividades específicas de enzimas antioxidantes de cultivares de cana-de-açúcar tratados com maturadores químicos. Aplicou-se o delineamento de blocos casualizados, com seis repetições, em esquema fatorial 9x2: ingredientes ativos (controle 0,00 L ha -1 , etefon 0,67 L ha -1 , glifosato 0,35 L ha -1 , MTD 1,00 L ha -1 , etil-trinexapac 0,80 L ha -1 , sulfumeturon-metil 0,02 kg ha -1 , etefon 0,34 L ha -1 + glifosato 0,15 L ha -1 , MTD 1,00 L ha -1 + glifosato 0,15 L ha -1 e sulfumeturon-metil 0,02 kg ha -1 + glifosato 0,15 L ha -1 ) e cultivares (RB85-5156 e RB85-5453), correspondentemente. Posteriormente à operação de colheita, realizada sessenta dias após a aplicação de maturadores, destinaram-se colmos e folhas ao laboratório, para determinação dos parâmetros tecnológicos de caldo, °Brix, Pol, Pureza, ATR e Fibras, e análise de atividades específicas das enzimas antioxidantes, superóxido dismutase (SOD), catalase (CAT), ascorbato peroxidase (APX) e peroxidase (POD), respectivamente. Houve rejeição de hipótese de nulidade, ao nível de interação entre as causas de variação, para CAT e POD; SOD, APX e todos os atributos de caldo foram influenciados, apenas, ao nível de efeitos isolados. Portanto, concluiu-se que plantas submetidas à aplicação de maturadores químicos exibiram qualidades de caldo superiores e sistemas antioxidantes enzimáticos mais reativos a radi...

“…In some species, both cultivated and wild, seed treatment with phytoregulators has been effective in promoting greater expression of physiological quality, as reported by Prado Neto et al (2007) for Genipapa americana L. and by Vendruscolo et al (2016) for Solanum lycopersicum L. Phytoregulators, also called "plant bioregulators", are exogenously applied synthetic substances which alter plant morphology and physiology and may lead to qualitative and quantitative changes in agricultural production (VIANA et al, 2015).…”

Physalis angulata L. (Solanaceae), popularly known as ‘camapu’, has high pharmacological and agroindustrial potential. However, because it essentially is a wild species, studies on the physiological quality of its seeds are still scarce. In this sense, the objective was to evaluate the physiological performance of P. angulata seeds as a function of pre-germination treatments with chemical promoters. For this, germination, first germination count, germination speed index and seedling emergence tests were performed. The substrate was previously moistened with solutions of gibberellic acid - GA3 (0.00, 0.02, 0.04, 0.06 and 0.08%), potassium nitrate - KNO3 (0.0, 0.2, 0.4, 0.6, 0.8 and 1.0%) and Stimulate® (0.00, 0.25, 0.50, 0.75, 1.00, 1.25 and 1.50%). Each chemical promoter constituted an independent experiment, in a completely randomised design, with four replicates of 25 seeds each. The three chemical promoters enhanced the physiological performance of P. angulata seeds, and the concentrations of 0.05% GA3, 0.4% KNO3 and 1.0% Stimulate® were most suitable.
