Abstract

CUNHA, Adriane Oliveira et al. Effects of substrata and containers dimensions on the quality of Tabebuia impetiginosa (Mart. Ex D.C.) Standl. seedlings. Rev. Árvore [online]. 2005, vol.29, n.4, pp.507-516. ISSN 0100-6762.  https://doi.org/10.1590/S0100-67622005000400002.

The growing demand for seedlings of native species has required research on the use of substrata and containers capable of producing seedlings with high initial growth and surviving rates after planting. This work aimed to evaluate the effects of substrata easily found in farms, and the size of containers used to produce seedlings of Tabebuia impetiginosa (Mart. ex D.C.) Standl. (Ipê roxo). The experiment was conducted in an experimental field of the Department of Agronomy-CCA/UFPB, District of Areia. The experiment was carried out in a randomized block design, totalizing 14 blocks. The treatments consisted of combinations of the following substratas: S1-subsoil and S2-subsoil plus organic compost and polyethylene bags with the following dimensions: I - 20 x 36.5 cm; II - 15 x 32 cm; III - 13 x 25.5 cm; IV - 13.5 x 9 cm. For all the studied variables, the container I and substratum S2 gave the best results. However, considering the difference among the results and the demand for substratum and handling in the first case, it is recommended the use of container II and substratum S2 in the production of seedlings of this species.

Keywords : Tabebuia impetiginosa; seedlings; polyethylene bags.
