Resumos

Experimentos realizados em casa de vegetação ou em laboratório, em Viçosa (MG), visaram determinar os sítios preferenciais de penetração do quinclorac em sementes e plântulas de Echinochloa spp. e Cucumis sativus L. cv. Caipira AG 221. O quinclorac foi eficientemente absorvido por semente, radícula, coleóptilo ou hipocótilo do capim-arroz e do pepino. As maiores reduções no alongamento e na massa seca do sistema radicular e aéreo ocorreram quando o herbicida foi absorvido por radículas, em ambas as espécies, indicando ser o sítio preferencial de penetração em estruturas jovens. O quinclorac produziu sintomas visuais de fitotoxicidade ou alterações morfológicas nas plantas tanto de pepino quanto de capim-arroz.

The experiments were carried out under greenhouse or laboratory conditions at Viçosa, State of Minas Gerais, Brazil, in order to determine the preferential sites of quinclorac uptake in seeds and seedlings of Echinochloa spp. and Cucumis sativus L. cv. Caipira AG 221. The quinclorac was efficiently uptaken by seed, radicle, coleoptile or hypocotyl of barnyardgrass and cucumber. The herbicide uptake by radicle produced great reduction on elongation and dry weight of shoots and roots in both species, indicating that radicle may be the preferencial site of quinclorac penetration in young structures. The quinclorac induced visual symptoms of phytotoxicity or morphological alterations in cucumber and barnyardgrass plants.

ABSTRACT

The experiments were carried out under greenhouse or laboratory conditions at Viçosa, State of Minas Gerais, Brazil, in order to determine the preferential sites of quinclorac uptake in seeds and seedlings of Echinochloa spp. and Cucumis sativus L. cv. Caipira AG 221. The quinclorac was efficiently uptaken by seed, radicle, coleoptile or hypocotyl of barnyardgrass and cucumber. The herbicide uptake by radicle produced great reduction on elongation and dry weight of shoots and roots in both species, indicating that radicle may be the preferencial site of quinclorac penetration in young structures. The quinclorac induced visual symptoms of phytotoxicity or morphological alterations in cucumber and barnyardgrass plants.

Index terms: cucumber, Cucumis sativus L., barnyardgrass, Echinochloa spp., herbicide.
