Efeito de diferentes substratos na germinação de <i>Chroma pyramidale</i> (Cav. ex Lam.) Urb. (Bombacaceae).

Abstract: O objetivo deste trabalho foi analisar o efeito de diferentes substratos na germinação de Ochroma pyramidale (Cav. ex Lam.) Urb. (Bombacaceae). O experimento foi conduzido em delineamento inteiramente casualizado com três tratamentos (substratos) e quatro repetições de 25 sementes. Foram testados os seguintes substratos: areia + vermiculita (1:1); vermiculita e, areia + serragem (1:1). Foi avaliado o efeito dos substratos pelo percentual de germinação das sementes, tempo médio de germinação e índice de velocid… Show more

“…At high temperatures, the sand is not able to maintain the moisture, with better efficiency in moderate temperature due to its low retention and poor distribution of water, excessively draining with the characteristic of dry at the upper portion (ALVINO; RAYOL, 2007 These results are in agreement with those obtained by Zamith and Scarano (2006), as well as by Lopes et al (2008) with other species from the Bombacaceae family, where the maximum germination percentage (95%) was observed for Pseudobombax grandiflorum (Cav.) A. Robyns.…”

“…Means followed by the lowercase letters between substrates and uppercase between the temperatures do not differ at 5% probability according to Scott-Knott´s test In the optimum temperature is possible to achieve the highest percentage of germination in a short interval (MIJAN et al, 2013 Looking from an economical prospective, both substrates (vermiculite and sand) are recommended for germination test because they are inexpensive, easy to use and with high availability (ALVINO; RAYOL, 2007). The significant interaction between temperature and substrate found in this study corroborate to the results found by Pereira et al (2014), who reported the efficiency of vermiculite and sand as substrates in the germination of forest seeds.…”

“…A vermiculita é de fácil manuseio, inorgânica, neutra, leve e com boa capacidade de absorção e retenção de água, destacando-se dos demais substratos, razão pela qual vem sendo bastante utilizada em testes com espécies florestais (Figliolia et al 1993, Albuquerque et al 1998, Silva & Aguiar 1998, Alvino & Rayol 2007, embora a areia apresente maior facilidade de aquisição e menor custo, e isto pode ser um fator importante para a escolha do substrato, com bons resultados nos testes (Silva et al 2006, Machado et al 2002.…”

“…Possibly the high seedlings emergence obtained with the substrate soil + vermiculite + humus and with soil + humus can be explained by the excellent capacity of water storage performed by the vermiculite and the humus (Alvino and Rayol, 2007). Also the characteristics of the used soil can influence, because it is a clay soil with great water absorption.…”
