Resumo: | The cold test has been employed mainly for corn seeds but its use is steadly growing for crops as cotton, soybean, common bean, pea, etc. It seems also to be true that for each of these crops the procedures of the cold test should be standardized. Thus, seed vigor of five cotton delinted seed lots was evaluated by means of different procedures of the cold test: soil plastic boxes, soil in rolled paper towel and rolled paper towel without soil. Seeds were exposed to 10°C during three, five and seven days. Simultaneously, seeds were submitted to the electrical conductivity and the accelerated aging vigor tests to make a comparison with the cold test. The paper towel method for five and seven days allowed, consistently, the detection of different vigor classes of seed lots when compared to the other cold test procedures as well as to the electrical conductivity and accelerated aging tests. The use of the paper towel as substratum and the exposure of seeds to 10°C for five days is therefore indicated as a reliable method for cotton seed vigor evaluation. |

O teste de frio tem sido usado principalmente para sementes de milho. Porém, seu uso em outras espécies como feijão, soja, algodão e ervilha tem crescido significativamente em todo o mundo. No entanto, ressalta-se a necessidade da padronização de metodologias do teste de frio de acordo com as características de cada espécie a ser testada. Dessa forma, com o objetivo de determinar a eficiência do teste de frio na avaliação do potencial fisiológico de sementes de algodão, cinco lotes do cultivar Delta Pine - Acala 90, deslintados quimicamente, foram submetidos a diferentes procedimentos: caixa com terra, rolo de papel com terra e rolo de papel sem terra, variando-se o período de exposição (três, cinco e sete dias) das sementes à baixa temperatura (10°C). Paralelamente, as sementes foram submetidas aos testes de condutividade elétrica e de envelhecimento acelerado, para comparação com os resultados obtidos nos diferentes procedimentos do teste de frio. A utilização de rolo de papel sem terra, com cinco e sete dias de exposição ao frio, permitiu classificar de maneira mais consistente, os lotes de sementes de algodão, em função do potencial fisiológico, com relação às informações obtidas nos testes de condutividade elétrica e de envelhecimento acelerado. O uso desse procedimento, com cinco dias de exposição a 10°C, pode ser indicado para avaliação do vigor de sementes de algodão. Universidade de São Paulo.
