Resumo: Sarcotesta, a mucilaginous layer found in papaya seeds, negatively affects the germination of papaya seeds and its removal has been manually performed. The use of sodium hypochlorite can be an alternative to manual removal of sarcotesta in papaya seeds. The objective of this study was to evaluate the effect of different active chlorine concentrations (0, 2, 4, 6 and 8%) during 24 hours of immersion, in different proportions (10:200, 50:200, 100:200, 200:200, 300:200, 400:200, 500:200 and 600:200) of seeds number and solution volume (mL) to identify the best combination for an effective remotion of sarcotesta to improve the germination process. Germination test and first count were performed. A completely randomized design with four replications was used. Regression analysis was performed for quantitative variables with significant effect by F-test at 5% probability. Papaya seeds immersion in the ratio of 10 seeds per 200 mL of NaOCl solution (10:200, i.e. 20 mL of solution per seed), at a 2% sodium hypochlorite concentration during 24 hours of imbibition, can be used as an alternative for sarcotesta remotion for freshly harvested papaya seeds, because besides the effective remotion of sarcotesta, this technique improves the germination process.

O uso do hipoclorito de sódio pode ser uma alternativa à remoção manual da sarcotesta. Objetivou-se avaliar o efeito de diferentes concentrações de cloro ativo (0, 2, 4, 6 e 8%), durante 24 horas de imersão, em diferentes proporções (10:200, 50:200, 100:200, 200:200, 300:200, 400:200, 500:200 e 600:200) entre sementes (número) e volume (mL) da solução de hipoclorito de sódio respectivamente, visando identificar a melhor combinação para a retirada efetiva da sarcotesta de maneira a contribuir no processo germinativo. Foram avaliados o teste de germinação e a primeira contagem. Empregou-se o delineamento estatístico inteiramente casualizado com quatro repetições. Para as variáveis quantitativas, que apresentaram efeito significativo pelo teste F a 5% de probabilidade, foi realizada a análise de regressão. A imersão de sementes de mamão na proporção de 10 sementes por 200 mL de solução de NaOCl (10:200, ou seja, 20 mL de solução por semente), na concentração de 2% de cloro ativo por 24 horas, pode ser uma alternativa para a retirada da sarcotesta em sementes recém-colhidas, pois, além da retirada efetiva da sarcotesta, favorece a germinação.Associação Brasileira de Tecnologia de Sementes2018-08-30T16:57:57Z2018-08-30T16:57:57Z2016-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfJESUS, V.
