Resumo: This work aimed to study in vitro interference of pesticides and ideal conditions for the germination and growth of papaya (Carica papaya L.) pollen tube. Four experiments were carried out in the Universidade Federal de Viçosa, State of Minas Gerais, Brazil, from March 1995 to March 1997. The largest pollen grain germination was obtained with pollen collection at the anthesis, with culture media contents of: agar 1%, sucrose 8% and 2.4-D 0.002%. Methamidophos, dimethoate, methyl thiophanate, benomyl, and permethrin did not present toxicity to the pollen grains. Pirimicarb, abamectin, and the spreader-sticker nonil fenoxi poli (etilenoxi) ethanol reduced the germination of the pollen grains. Sulfur reduced germination and pollen tube length. Chlorothalonil, dicofol, mancozeb, naled, captan, and copper oxychloride inhibited completely the pollen grain germination.

Para a realização deste trabalho, foram conduzidos quatro experimentos na Universidade Federal de Viçosa, Estado de Minas Gerais, de março de 1995 a março de 1997. Verificou-se que os grãos-de-pólen do mamoeiro possuem um tempo de germinação menor que 12 horas. A maior porcentagem de germinação foi obtida com a coleta de pólen até a antese e com o meio de cultura contendo 1% de ágar, 8% de sacarose e 0,002% de 2,4-D. O metamidofós, dimetoato, tiofanato metílico, benomil e permetrina não apresentaram toxicidade aos grãos-de-pólen. O pirimicarb, a abamectina e o espalhante adesivo nonil fenoxi poli (etilenoxi) etanol reduziram a germinação dos grãos-de-pólen. O enxofre reduziu tanto a germinação quanto o comprimento do tubo polínico. O clorotalonil, dicofol, mancozeb, naled, captan e oxicloreto de cobre inibiram completamente a germinação dos grãos-de-pólen.Universidade Estadual de Maringá2008-04-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/216010.4025/actasciagron.v27i1.2160Acta Scientiarum.
