          Abstract

          Em um experimento conduzido em área experimental da EMBRAPA, UEPAE de Porto Velho, Rondônia, localizado no km 5,5 da BR-364, com latitude sul 8º46'5", longitude 63°5' de Greenwich e altitude de 96,3 metros acima do nível do mar, avaliou - se em 5 cultivares de Pimenta - do - reino (Piper nigrum L.), por ocasião da primeira produção, 18 meses após plantio, a incidência da doença antracnose provocada pelo fungo Colletotrichum gloeosporioides e a porcentagem de desfolha das plantas, correlacionando-as com a produtividade dos cultivares. Os resultados obtidos permitiram concluir que: o cultivar Guajarina mostrou ser menos susceptível a antracnose e mais resistente a desfolha; os cultivares Bragantina, Cingapura e Djambi comportaram-se de maneira semelhante com relação a desfolha; os cultivares Bragantina e Cingapura, foram iguais entre si e menos susceptíveis com relação a antracnose quando comparados com os cultivares Djambi e Belantung, enquanto que o cultivar Belantung mostrou ser mais susceptível à antracnose e menos resistente a desfolha.

          Translated abstract

          In an experiment carried out in an experimental area of EMBRAPA (Brazilian Agriculture Research Enterprise) UEPAE (Unit for Execution of Research) of Porto Velho, State of Rondonia, Brazil, located at km 5.5 of the BR-364 Highway, latitude 8°46'5"S, longitude 63°5' Greenwich and altitude 96.3m above sea level, evaluations were made of both the occurence of anthracnose caused by the fungus (Colletotrichum goeosporioides) in 5 cultivars of pepper (Piper nigrum L.) at the time of the first yield, 18 months after planting and of the leaves, correlating them with productivity of the cultivars. The results obtained led to the following conclusions: the cultivar Guajarina showed to be less susceptible to anthracnose and more resistant to fall of the leaves; the cultivars Bragantina, Cingapura and Djambi behaved similarly as to fall of the leaves; the cultivars Bragantina and Cingapura had the same behavior and were less susceptible to anthracnose when compared with cultivars Djambi and Belantung, while the cultivars Belantung showed to be more susceptible to anthracnose and less resistant to fall of the leaves.
