Este ensaio comparou os efeitos de quatro tubetes no crescimento de mudas deCordia trichotoma (Vell.) Arrab. ex steud, e Jacaranda micranta Cham. at´e 180 dias ap´os
o plantio. Foram utilizados tubetes pl´asticos de se¸c˜ao circular e volume de 55 cm3 , 120
cm3, 180 cm3, e 300 cm3 preenchidos com substrato comercial. Os resultados indicaram
que, durante a fase de viveiro, os tubetes menores causaram diminui¸c˜ao da massa seca do
sistema radicular e do n´umero de radicelas. O crescimento das mudas de caroba e de louropardo
em altura e diˆametro plantadas a campo resultou em similaridade estat´ıstica entre as
originadas de tubetes de 120 cm3, 180 cm3, e 300 cm3 ao final de 180 dias ap´os plantio. O
plantio de mudas das esp´ecies testadas em solos de boa fertilidade possibilita a utiliza¸c˜ao de
tubetes de 120 cm3 com economia de substrato, de espa¸co de viveiro e de esfor¸co no plantio.
