Resumo: | The objective of this study was to evaluate the influence of the maturation stage of the fruit on the physical characteristics and germination of Schefflera morototoni pyrenes submitted to pre-germination treatments. Fruits with green and purplish green coloration were collected from 14 accesses, pulped in running water, discarding the hollow pyrenes, after counting, together with retracted and oxidized endosperm, and using the uniform pyrenes (with greenish endosperm occupying the whole cavity of the pyrene). The experiment was conducted in a completely randomized design in a 2 x 5 factorial scheme (stages of fruit maturation and pre-germination treatments), with four repetitions in parcels containing 25 pyrenes. For greater capacity and germination speed of the pyrenes, fruits should be harvested when they present a purplish green coloration, while discarding those with hollow pyrenes, with retracted or oxidized endosperm. The germination capacity of the pyrenes with uniform endosperm varied between 50 and 60%, with the beginning of the process at about 40 days after planting and continuing for up to 60 days in vermiculite. Pulped pyrenes, dried and soaked in water at 60ºC for 5 minutes, followed by soaking in water at room temperature for 12 hours began the germination process in less time, in relation to those pulped, dried, scarified and soaked for 6 hours. The fruit endocarp is permeable and rigid; however, it presents a natural opening when soaked. |

Frutos com coloração verde e verde-arroxeada foram coletados de 14 acessos, despolpados em água corrente, descartando-se, após contabilização, os pirênios chochos, com endosperma retraído e oxidado, utilizando-se os uniformes (com endosperma esverdeado ocupando toda a cavidade do pirênio). O delineamento experimental foi o inteiramente casualizado em esquema fatorial 2 x 5 (estádios de maturação dos frutos e tratamentos pré-germinativos), com quatro repetições em parcelas contendo 25 pirênios. Verificou-se que, para maior capacidade e velocidade de germinação dos pirênios, os frutos devem ser colhidos quando apresentarem coloração verde-arroxeada, descartando-se aqueles com pirênios chochos, endosperma retraído ou oxidado. A capacidade de germinação dos pirênios com endosperma uniforme varia entre 50 e 60%, com início do processo em cerca de 40 dias após semeadura, se estendendo por até 60 dias em vermiculita. Pirênios despolpados, secos e embebidos em água a 60oC por 5 minutos, seguida da embebição em água à temperatura ambiente por 12 horas iniciam o processo de germinação em menor tempo, em relação aos despolpados, secos, escarificados e embebidos por 6 horas. O endocarpo dos frutos é permeável e rígido, no entanto, apresenta abertura natural quando embebido.Universidade Federal de Santa Maria2010-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/205810.5902/198050982058Ciência Florestal; Vol. 20 No. 3 (2010); 429-437Ciência Florestal; v. 20 n. 3 (2010); 429-4371980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2058/1237Anastácio, Maristela RosáliaSantana, Denise Garcia deOliveira, Roberta Camargos deBabata, Marcela MayumiOliveira, Carlos Alberto Alves deinfo:eu-repo/semantics/openAccess2017-05-05T10:30:57Zoai:ojs.pkp.sfu.ca:article/2058Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-05T10:30:57Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
