Resumo: | http://dx.doi.org/10.5902/198050986616In order to add knowledge regarding to Apuleia leiocarpa (Vogel) J. F. Macbr., it was analyzed its time of flowering and fruiting, fruit morphology, seed germination, seedling and changes, as well as its physical characteristics, germination and emergence of seeds of different trees. From the selection of 20 mother trees, observations were made monthly in order to ascertain the presence of flowers and fruits. After maturation, the fruits were collected, the seeds extracted from fruits, processed and separated by matrix, from which samples were taken for the determination of weight, moisture content, germination tests and emergency conditions in laboratory and nursery. Copies of fruits and seeds were stored in 70% ethanol for the later morphological description. The greater presence of flowers grápia occurred from September to October and fruits from January to March, with a variation in the time and frequency of mother trees in both clones as well as the estimated amount of fruits and seeds in each year. Morphologically, the result is simple, indehiscent pod and dry, with 1-2 seeds, which are brown in color with visible linear scar, micropyle and raphe undeveloped near the hilum. Internally, the seed is albuminous, with axial embryo, spatulate, occupying three quarters of the inner region, with large and foliaceous cotyledons. The germination is epigeal and the seedling phanerocotyledonal. The fruit length ranged from 1,45 to 3,01 cm, width from 1,20 to 2,07 cm and thickness from 0,20 to 0,30 cm. For the seeds, 1,2 to 2,1 cm long, 0,6 to 0,95 cm wide and 0,1 to 0,2 cm thick. There were differences between the parent trees for the physical and physiological tests, where the number of seeds per kilogram ranged from 8.713 to 11.197, the moisture content from 12, 43 to 27, 97% germination 13 to 96% and the emergengc from 26 to 88%. It was concluded that seeds from individuals of the same population have significant physical and physiological variations, either because of environmental or genetic factors or due to the micro habitat. Thus, although providing better genetic representation, they reduce the homogeneity of the seed lots. |

F. Macbr., analisou-sesua época de floração e frutificação, a morfologia de frutos, sementes, germinação, plântula e muda, comotambém características físicas, germinação e emergência de sementes de diferentes árvores matrizes. A partirda seleção de 20 árvores matrizes, foram realizadas observações mensalmente, a fim de averiguar a presençade flores e frutos. Após a maturação dos frutos, estes foram coletados, suas sementes extraídas, beneficiadase separadas por matriz, de onde foram retiradas amostras para determinação do peso, teor de água, testesgerminativos e de emergência em condições de laboratório e viveiro. Exemplares de frutos e sementesforam armazenados em álcool 70 %, para posterior descrição morfológica. A maior presença de flores degrápia ocorreu de setembro a outubro e de frutos, de janeiro a março, havendo variações em relação à épocae à frequência de árvores matrizes nas fenofases, assim como a quantidade estimada de frutos e sementespresentes em cada ano. Morfologicamente, o fruto é simples, vagem seca e indeiscente, com 1 a 2 sementescada, sendo estas de coloração castanha, com cicatriz linear visível, rafe pouco desenvolvida e micrópilapróxima ao hilo. Internamente, a semente é albuminosa, com embrião axial, espatulado, ocupando ¾ daregião interna, com cotilédones foliáceos e grandes. A germinação é epígea e a plântula fanerocotiledonar.O comprimento dos frutos variou de 1,45 a 3,01 cm, a largura de 1,20 a 2,07 cm e a espessura de 0,20 a 0,30cm. Para as sementes, 1,2 a 2,1 cm de comprimento, 0,6 a 0,95 cm de largura e 0,1 a 0,2 cm de espessura.Houve diferenças entre árvores matrizes para os testes físicos e fisiológicos, onde o número de sementespor quilograma variou de 8.713 a 11.197, o grau de umidade de 12,43 a 27,97 %, a germinação de 13 a96 % e a emergência de 26 a 88 %. Concluiu-se que sementes provenientes de indivíduos de uma mesmapopulação possuem variações expressivas quanto às características físicas e fisiológicas, seja em funçãodo ambiente, fator genético ou do micro-habitat. Assim, apesar de proporcionar melhor representatividadegenética, reduzem a homogeneidade do lote de sementes.Universidade Federal de Santa Maria2012-09-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/661610.5902/198050986616Ciência Florestal; Vol. 22 No. 3 (2012); 477-491Ciência Florestal; v. 22 n. 3 (2012); 477-4911980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/6616/4017Felippi, MarcieleMaffra, Charles Rodrigo BelmonteCantarelli, Edison BisogninAraújo, Maristela MachadoLonghi, Solon Jonasinfo:eu-repo/semantics/openAccess2017-04-20T12:59:41Zoai:ojs.pkp.sfu.ca:article/6616Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-20T12:59:41Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
