Resumo: The existence of pollinators able to promote xenogamy is a decisive factor in the yield of orchards. As it is allogamous, due to gametophytic self-incompatibility, most European pear cultivars do not produce fruits with seeds in the absence of pollinating insects. Therefore, the correct management and quality of Apis mellifera hives installed in the orchards are indispensable to ensure economically viable yields. In this context, we aimed to evaluate some aspects of the driven pollination system with A. mellifera that can decisively interfere with pollination effectiveness in a commercial orchard of European pear under the ecological conditions of Santa Catarina’s Mountain Plateau, in Brazil’s South region. We observed low visitation of bees on the pear flowers, possibly due to two factors: floral competition and insufficient density of hives installed in the orchard. No pollen deposition was observed on the stigmas, something which confirms pollination failure in the area. The quality of rented hives showed differences between years, with presence of the mite Varroa destructor and the microsporidian Nosema ceranae, which may have contributed to the depopulation of hives within the flowering period and, consequently, the decreased pollen deposition on the stigmas of flowers of the main fruit-producing cultivar.

Por ser alógama, devido à autoincompatibilidade gametofítica, a maioria das cultivares europeias de pereiras não produzem frutos com sementes sem a presença de insetos polinizadores. Portanto, o correto manejo e a qualidade das colmeias de Apis mellifera instaladas nos pomares são imprescindíveis para assegurar produções economicamente viáveis. Nesse contexto, objetivou-se avaliar alguns aspectos do sistema de polinização dirigida com A. mellifera que podem interferir decisivamente na eficiência da polinização em um pomar comercial de pereira portuguesa nas condições ecológicas do planalto serrano catarinense, no Sul do Brasil. Foi observada uma baixa visitação de abelhas nas flores de pereira, possivelmente devido a dois fatores: competição floral e densidade insuficiente de colmeias instaladas no pomar. Não foi observada a deposição de pólen nos estigmas, o que confirma a deficiência de polinização na área. A qualidade das colmeias alugadas apresentou diferenças entre os anos, com presença do ácaro Varroa destructor e do microsporídeo Nosema ceranae, os quais podem ter contribuído para o despovoamento das colmeias durante o período de floração e, consequentemente, redução da deposição de pólen no estigma das flores da cultivar produtora de frutos.Universidade Federal de Santa Catarina2015-03-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2015v28n2p7310.5007/2175-7925.2015v28n2p73Biotemas; v. 28 n. 2 (2015); 73-862175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2015v28n2p73/29244Copyright (c) 2015 André Amarildo Sezerino, Afonso Inácio Orthinfo:eu-repo/semantics/openAccessSezerino, André AmarildoOrth, Afonso Inácio2017-10-19T16:36:29Zoai:periodicos.ufsc.br:article/34066Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2017-10-19T16:36:29Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false
