Effects of four delinting methods on the germination and longevity of cottonseeds of the cultivar IAC 13-1, treated and non-treated with the fungicide PCNB 75% were studied. The seeds were stored in uncontrolled conditions at Campinas, State of São Paulo for a period of 21 months. Seeds delinted by gas and treated with fungicide maintained germination rates higher than 80 %, up to 15 months storage. At the end of the storage period, the seeds that presented germination higher than 60% were those delinted by gas or acid and treated with fungicide. Seeds delinted by gas or acid presented higher germination percentages and stored longer than those delinted by mechanical means or by flame. Aside the delinting method, the fungicide treatment was beneficial to the germination of the seeds.
