Initial growth and quality of jussara palm seedlings cultivated in biosolid-based substrates

All palms present ornamental appeal and may be widely used in landscaping, especially the native ones because of their ecological importance, such as jussara palm (Euterpe edulis Mart.). In this sense, aiming at maximum plant development urban environment, it is necessary to use high-quality seedlings; substrate one key factors that directly influence it. The objective study was evaluate initial growth seedlings cultivated biosolid-based substrates, which a material good characteristics besides attending sustainability issues. experimental design entirely randomized with six treatments consisted substrates composed by biosolid (BIO) subsoil (SS) different proportions (v:v): 100% SS - control; 20% BIO + 80% SS; 40% 60% BIO. Seedlings were greenhouse evaluated according following variables: height aerial part; root length; collar diameter; leaf number; dry mass part roots; total mass; chlorophyll content; part/collar diameter rate; part/dry roots Dickson Quality Index. There significant effect (p < 0.05) for all characteristics. biosolid, combined subsoil, composition, potentially appropriate seedling production. Higher toxic growth.
