Resumo: | This work was made in a rubber plantation of clone RRIM 600, seven years old, in Colina, SP, Brazil. Its objective was to study the time of harvest and quality of rubber seeds (Hevea braslliensis Muell. Arg.), during the years of 1986 and 1987. The harvest was made with weekly intervals for both years, after the beginning of the seed fullup and at its and. The following parameters were determined: moisture content of seeds, number of seeds per plant, weight of seeds per plant, seed individual weight, number of seeds per kg, 100 seeds weight, emergence percentage and emergence speed. The results showed that 1. the moisture content of seeds decreased during the harvest period, for both years; 2. production and quality of seeds were variable in function of the harvest period, in the same year and year by year, 3. in both years, the highest values of seed weight and the percentage of seed emergence were obtained in a period referential to the peak of seeds fullup; and 4. the physiological quality of seeds harvested in 1986 was superior to the quality of those harvested-in 1987. |

Arg.) durante os anos de 1986 e 1987. As sementes foram colhidas a intervalos semanais durante os dois anos, após o início e após o fim do seu enchimento. Foram determinados os seguintes parâmetros: teor de umidade das sementes; número de sementes por planta; peso de sementes por planta; peso individual das sementes; número de sementes por kg; peso de 100 sementes, percentagem de emergência, e rapidez de emergência. Os resultados mostram que: 1. o teor de umidade das sementes diminuiu durante a época da coleta; 2. a produção e a qualidade das sementes apresentaram-se variáveis em função da época da coleta, no mesmo ano e ano após ano; 3. em ambos os anos, os valores mais elevados do peso das sementes e a percentagem de emergência foram obtidos num período referencial ao pico do enchimento das sementes; e 4. a qualidade fisiológica das sementes colhidas em 1986 foi superior à das colhidas em 1987.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraVieira, Roberval DaitonAntonio, Renato LollatoAguiar, Ivor Bergemann deMalheiros, Euclides Braga2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16044Pesquisa Agropecuaria Brasileira; v.24, n.7, jul. 1989; 851-856Pesquisa Agropecuária Brasileira; v.24, n.7, jul. 1989; 851-8561678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16044/10210info:eu-repo/semantics/openAccess2014-08-28T17:12:46Zoai:ojs.seer.sct.embrapa.br:article/16044Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-28T17:12:46Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
