Produção de mudas de ipê-branco em diferentes substratos

Abstract: Objetivou-se, com este trabalho, avaliar a emergência de plântulas e o crescimento no viveiro de mudas de ipê-branco (Tabebuia roseo-alba (Ridl.) Sandwith) em diferentes substratos. Foram realizados dois experimentos independentes. O estudo da emergência foi realizado em seis substratos: 1- Plantmax® - P; 2- vermiculita - V; 3- areia - A; 4- solo + areia - SA (1:1); 5- solo + casca de arroz carbonizada - SC (1:1); 6- solo + areia + casca de arroz carbonizada - SAC (2:1:1) (v/v), sendo utilizado o delineamento … Show more

“…There was no significant difference in the treatments within and between the two soil textural classes in variables AP, SC and TC (Table 5). However, the values obtained in this experiment are similar to those obtained by Macedo et al (2011) in ipê-roxo (Handroanthus impetiginosus) seedlings with different substrates and shadings and to those obtained by Goulart et al (2017) when testing doses and nitrogenated sources in the production of ipê-amarelo seedlings. LAP is an excellent parameter to measure the quality of forest species seedlings, above all because it is easy and quick to measure and non-destructive.…”

“…Por outro lado, para as mudas de ipê-branco (Tabebuia roseo-alba Ridl. Sandwith) cultivadas em diferentes substratos houve incremento dessa variável no tratamento com casca de arroz carbonizada e solo (Macedo et al, 2011).…”

“…The specific surface area of the roots of earpod tree seedlings was higher with the poultry litter mix at a ratio of 33% and 41% in the commercial substrate and in the peat, respectively ( Figure 1E). Macedo et al (2011) mention the higher availability of nutrients as a factor that is responsible for the higher root growth of white ipê (Tabebuia roseoalba) on substrates with soil or sand mixed with semi-decomposed poultry litter. Thus, the increase of the root specific surface area, added to the increase in the root dry matter with the addition of organic compound, in this case poultry litter at the proper ratio, allows greater root expansion, with the production of fine roots, providing greater absorption of water and nutrients (Kiehl, 2008).…”
