Resumo: | Araucaria angustifolia is a species of ecological and social-economic importance in the southern Brazil region, but it is at risk of extinction. Its seeds are classified as recalcitrant, requiring storage under controlled temperature and humidity to obtain greater longevity. Another aspect is the seed health quality, which is impaired by high seed moisture content that causes fungus proliferation and may reduce germination and seedling quality. The objective of this study was to evaluate the physiological and sanitary quality of araucaria seeds treated with 0.5, 1 and 3 % of sodium hypochlorite (NaClO) and stored at different periods (2, 4, 6, 8 and 12 months). The seed quality was evaluated by germination, vigor and seed health tests. The disinfection of seeds, regardless of the concentration used, temporarily delayed the seed germinations, but did not negatively affect seedling emergence. After 12 months of storage, the seeds showed infection by Schizophyllum commune, which caused the reduction of the germination. The seeds treated with NaClO showed lower fungal incidence, especially Schizophyllum commune, ensuring the seed health quality during storage for 12 months. The treatment with NaClO positively favors the physiological quality of Araucaria seeds that will be stored for a period exceeding four months. |

Sua semente é classificada como recalcitrante, necessitando armazenamento sob temperatura e umidade relativa controladas para maior longevidade. Outro aspecto refere-se à qualidade sanitária das sementes, a qual é prejudicada pelo elevado teor de água que causa a proliferação de fungos, os quais podem reduzir a germinação. Este trabalho teve como objetivo avaliar a qualidade sanitária e fisiológica de sementes de araucária desinfestadas com solução de hipoclorito de sódio (NaClO) a 0,5; 1 e 3 % e submetidas a diferentes períodos de armazenamento (2, 4, 6, 8 e 12 meses). A qualidade das sementes foi avaliada pelos testes de germinação, vigor e sanidade. A desinfestação das sementes, independentemente da concentração utilizada, retardou temporariamente a germinação das mesmas, porém, não afetou negativamente a emergência das plântulas. Após 12 meses de armazenamento, verificou-se a infecção das sementes por Schizophyllum commune, o que causou a redução da germinação. As sementes tratadas com NaClO apresentaram menor incidência de fungos, especialmente Schizophyllum commune, garantindo a qualidade sanitária das mesmas durante o armazenamento por 12 meses. O tratamento com NaClO favorece positivamente a qualidade fisiológica das sementes de araucária que serão armazenadas por período superior a 4 meses.Universidade Federal de Santa Maria2017-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2774910.5902/1980509827749Ciência Florestal; Vol. 27 No. 2 (2017); 643-654Ciência Florestal; v. 27 n. 2 (2017); 643-6541980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/27749/pdfCopyright (c) 2017 Ciência Florestalinfo:eu-repo/semantics/openAccessHennipman, Hagata Siqueirados Santos, Álvaro FigueredoVieira, Elisa Serra NegraAuer, Celso Garcia2017-07-08T02:12:01Zoai:ojs.pkp.sfu.ca:article/27749Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-07-08T02:12:01Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
