Abstract
A alelopatia é muito comum em gramíneas como a Brachiaria brizantha e B. decumbens, podendo representar um problema em pastagens consorciadas com Stylosanthes, já que, nessa situação, a perpetuação da leguminosa depende da ressemeadura natural. Apesar da grande quantidade de sementes de estilosantes produzidas anualmente, nessas pastagens consorciadas, observa-se, em campo, pequena quantidade de plantas jovens, o que pode ser atribuído a um possível efeito alelopático da gramínea. Considerando a importância da alelopatia no consórcio de braquiárias com estilosantes, testou-se o potencial alelopático de extratos de Brachiaria brizantha e B. decumbens na germinação de sementes de três espécies de estilosantes. Verificou-se que há efeito alelopático negativo de B. brizantha e B. decumbens na germinação de sementes de Stylosanthes guianensis e somente de B. decumbens na germinação de S. capitata; há efeito alelopático positivo de B. brizantha nas sementes de S. macrocephala; não há efeito alelopático de B. brizantha na germinação de sementes de S. capitata e nem de B. decumbens em S. macrocephala.
The allelopathy is very common in grasses such as Brachiaria brizantha and Brachiaria decumbens, could represent a problem in pastures consortium with Stylosantes since, in this situation, the perpetuation of the legume dependent natural reseed. In spite of the great amount of estilosantes seed produced annually in those pastures consortium, it is observed in field, small amount of young plants, which can be attributed to a possible allelopathic effect of the grass. Considering the importance of allelopathy in the consortium of Brachiaria with estilosantes, we tested the allelopathic potential of extracts of B. brizantha and B. decumbens on seed germination of three estilosantes species. It was found that there allelopathic negative effect of B. brizantha and B. decumbens on seed germination of Stylosanthes guianensis and only of B. decumbens in seed S. capitata; there allelopathic positive effect of B. brizantha on germination of S. macrocephala; there is no allelopathic effect of B. brizantha on seed germination of S. capitata neither of B. decumbens in S. macrocephala.
