oai:repositorio:1-14203 Alguns aspectos da biologia floral de Annona sericea Dun. (Annonaceae) Webber, Antonio Carlos This paper presents the basic characteristic of the floral biology of Annona sericea Dun. Observations were based on five adult trees located on the INPA Campus in Manaus, AM. The flowers of Annona sericea Dun. are cantharophilous with the temperature of the flower rising to 6°C above of nighttime temperature. Insect visitors observed were beetles of the family Chrysomelidae (likely pollinators) and flies of the family Sciaridae (occasional pollinators). The beetles feed on the internal parts of the petals and also mate inside the flowers. The synchronous shedding of the stigmas and subsequent dehiscence of the anthers on any given plant precludes the possibility of self-pollination both at the level of the flower and individual tree however the species is self-compatible. Pollen fertility is 96%, however the natural fruit-set is very low. São apresentados neste trabalho alguns aspectos da biologia floral de Annona sericea Dun. As suas flores apresentam características de cantarofilia e os insetos visitantes são besouros Chrysomelidae (provável polinizador) e moscas Sciaridae (eventualmente polinizador acessório). Os besouros alimentam-se da parte interna das pétalas e também copulam no interior da flor. A temperatura das flores se eleva até 6°C além da temperatura ambiente, no período noturno. É mostrado um esquema da queda dos estigmas e posterior descarga do pólen. A flor não pode ser autopolinizada, pois os estigmas caem antes da descarga do pólen, porém ela é autocompatível. A fertilidade polínica é de 96%. todavia o número de frutos formados naturalmente é pequeno. 2020-04-24T16:29:47Z 2020-04-24T16:29:47Z 1981 Artigo https://repositorio.inpa.gov.br/handle/1/14203 10.1590/1809-43921981111061 pt_BR Volume 11, Número 1, Pags. 61-65 Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Acta Amazonica |

This paper presents the basic characteristic of the floral biology of Annona sericea Dun. Observations were based on five adult trees located on the INPA Campus in Manaus, AM. The flowers of Annona sericea Dun. are cantharophilous with the temperature of the flower rising to 6°C above of nighttime temperature. Insect visitors observed were beetles of the family Chrysomelidae (likely pollinators) and flies of the family Sciaridae (occasional pollinators). The beetles feed on the internal parts of the petals and also mate inside the flowers. The synchronous shedding of the stigmas and subsequent dehiscence of the anthers on any given plant precludes the possibility of self-pollination both at the level of the flower and individual tree however the species is self-compatible. Pollen fertility is 96%, however the natural fruit-set is very low. |
