Resumo: | Oxidation affects in vitro growth, due to the release of phenolic compounds, resulting in tissue darkening and, consequently, in the death of explants and plants. Therefore, this work aimed to study the effect of ascorbic acid and polyvinylpyrrolidone (PVP) in the in vitro cultivation of yam, aiming at reducing or eliminating the oxidation of explants and optimizing the growth of genotypes D. alata var. purpurea (Roxb.) A. Pouchet and D. rotundata Poir. In this experiment, nodal segments of approximately 1 cm in size, extracted from plants previously cultivated in vitro, were introduced into test tubes containing 10 mL of 2GGC culture medium, added with 30 g L-1 of sucrose, solidified with 2.2 g L-1 of Phytagel® and pH adjusted to 5.8 before autoclaving. Two antioxidants were added to the basic medium, making up two distinct experiments. In the first experiment, ascorbic acid was used at concentrations of 0 mg L-1; 25mg L-1; 50 mg L-1; 75 mg L-1 and 100 mg L-1; and in the second, PVP, at doses of 0 mg L-1; 50 mg L-1; 100 mg L-1; 150 mg L-1 and 200 mg L-1. Each experiment was installed in a completely randomized design, in a 5 x 2 factorial scheme (antioxidant concentrations x genotypes), containing 12 replicates per treatment. After 90 days of maintenance in the growth room, plant development was evaluated and it was observed that the antioxidants ascorbic acid and polyvinylpyrrolidone did not improve the growth variables. |

Por tanto, este trabajo tuvo como objetivo estudiar el efecto del ácido ascórbico y polivinilpirrolidona (PVP) en el cultivo in vitro de ñame, con el objetivo de reducir o eliminar la oxidación de explantes y optimizar el crecimiento de D. alata var. purpurea (Roxb.) A. Pouchet y D. rotundata Poir. En este experimento se introdujeron segmentos nodales de aproximadamente 1 cm de tamaño, extraídos de plantas previamente cultivadas in vitro, en tubos de ensayo que contenían 10 mL de medio de cultivo 2GGC, adicionados con 30 g L-1 de sacarosa, solidificado con 2.2 g L-1 de Phytagel® y el pH se ajustó a 5,8 antes de esterilizar en autoclave. Se agregaron dos antioxidantes al medio básico, formando dos experimentos distintos. En el primer experimento, se utilizó ácido ascórbico en concentraciones de 0 mg L-1; 25 mg L-1; 50 mg L-1; 75 mg L-1 y 100 mg L-1; y en el segundo, PVP, a dosis de 0 mg L-1; 50 mg L-1; 100 mg L-1; 150 mg L-1 y 200 mg L-1. Cada experimento se instaló en un diseño completamente al azar, en un esquema factorial 5 x 2 (concentraciones de antioxidantes x genotipos), conteniendo 12 réplicas por tratamiento. Luego de 90 días de mantenimiento en la sala de crecimiento, se evaluó el desarrollo de la planta y se observó que los antioxidantes ácido ascórbico y polivinilpirrolidona no mejoraron las variables de crecimiento.A oxidação afeta o crescimento in vitro, em função da liberação de compostos fenólicos, resultando no escurecimento dos tecidos e, por consequência, na morte de explantes e de plantas. Diante disso, este trabalho teve como objetivo estudar o efeito do ácido ascórbico e do polivinilpirrolidona (PVP) no cultivo in vitro do inhame, visando a redução ou eliminação da oxidação dos explantes e a otimização do crescimento dos genótipos D. alata var. purpurea (Roxb.) A. Pouchet e D. rotundata Poir. Nesse experimento, segmentos nodais de aproximadamente 1 cm de tamanho, extraídos de plantas previamente cultivados in vitro, foram introduzidas em tubos de ensaio contendo 10 mL de meio de cultura 2GGC, acrescido de 30 g L-1 de sacarose, solidificado com 2,2 g L-1 de Phytagel® e pH ajustado a 5,8 antes da autoclavagem. Ao meio básico foram acrescidos dois antioxidantes, compondo dois experimentos distintos. No primeiro experimento, foi utilizado o ácido ascórbico nas concentrações de 0 mg L-1; 25 mg L-1; 50 mg L-1; 75 mg L-1 e 100 mg L-1; e no segundo o PVP, nas doses de 0 mg L-1; 50 mg L-1; 100 mg L-1; 150 mg L-1 e 200 mg L-1. Cada experimento foi instalado em delineamento inteiramente casualizado, em esquema fatorial 5 x 2 (concentrações de antioxidante x genótipos), contendo 12 repetições por tratamento. Após 90 dias de manutenção em sala de crescimento, procedeu-se a avaliação do desenvolvimento das plantas e observou-se que os antioxidantes ácido ascórbico e polivinilpirrolidona não promoveram melhorias nas variáveis de crescimento.Research, Society and Development2021-07-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1781210.33448/rsd-v10i9.17812Research, Society and Development; Vol. 10 No. 9; e10510917812Research, Society and Development; Vol. 10 Núm. 9; e10510917812Research, Society and Development; v. 10 n. 9; e105109178122525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/17812/15955Copyright (c) 2021 Denise dos Santos Vila Verde; Maria Inês de Souza Mendes; Antônio da Silva Souza; Camila Rodrigues Pinto; Leila Vasconcelos Costa Nobre; Jorge Eduardo dos Santos Melo; Carlos Alberto da Silva Ledohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessVerde, Denise dos Santos VilaMendes, Maria Inês de SouzaSouza, Antônio da SilvaPinto, Camila Rodrigues Nobre, Leila Vasconcelos CostaMelo, Jorge Eduardo dos SantosLedo, Carlos Alberto da Silva2021-09-12T14:28:06Zoai:ojs.pkp.sfu.ca:article/17812Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:38:05.122008Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
