Efeito de diferentes substratos na emissão de brotações de estacas e desenvolvimento de mudas de pimenta-do-reino

Abstract

The propagation of black pepper Piper mgrum for plantation is carried out through cuttingsfrom stockplant branch. This propagation procedure possibility to get early production than from seeds that it is feasible only for especies improvement. Although the cutings can be planted. without prior rooting. that techniques is very expensive due to be a very time consuming task for replanting. The major concern with the black pepper cultivation is the disease caused by the fungus of genera Fusarium and Phytophthora The disease occurrence could occur due to infected cuttings into the propagator or in thestand. Therefore I recommended for cuttings production on esteril substract into the propagator. In this trial was used three different substract as seedbed in the propagator such as: Washed sand; rice burned shell and wood burned dust. The results showed better rooting for treatments with rice burned shell and burned wood dust.
