EFEITO DE DIFERENTES SUBSTRATOS NO DESENVOLVIMENTO DE MANDACARU (Cereus jamacaru P. DC.), FACHEIRO (Pilosocereus pachycladus RITTER), XIQUEXIQUE (Pilosocereus gounellei (A. WEBWR EX K. SCHUM.) BLY. EX ROWL.) E COROA-DE-FRADE (Melocactus bahiensis BRITTON & ROSE)

Abstract

Different rooting average were tested to identify those whch would provide the best conditions for growth of mandacaru (Cereus jamacaru P.. DC.), facheiro (Pilosocereus pachycladus Ritter), xiquexique (Pilosocereus gounellei (A. Webwr ex K. Schum.) Bly. ex Rowl.) and coroa-de-frade (Melocactus bahiensis Britton & Rose). five different compositions for rooting average were (sand; soil; sand + soil; sand + cattle manure; soil + cattle manure) the study was carried out from september of 2004 to december of 2005, in an area room temperature at Embrapa semi-arid, Petrolina, PE, Brazil. the substrate composed with sand + cattle manure and soil + cattle manure rooting medium showing the highest rates. In relation to the development of the system to radicular of the cactáceas was verified that in treatment 1 (sand) all had presented the biggest values in length terms. The growth in height of the cactáceas was influenced by different analyzed substrata. Between substrate, optimum cattle manure was with ground.
