<em>In vitro</em> interference of pesticides and ideal conditions for papaya (<em>Carica papaya</em> L.) pollen tube germination and growth
Abstract
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.Downloads
