Para estabelecer plantios florestais, há que se atentar para a produção de mudas, que também deve ser de qualidade. Diante disso, o presente trabalho teve por objetivo avaliar algumas combinações entre substrato comercial, solo, e diferentes materiais orgânicos, e seus efeitos no crescimento e fisiologia de mudas de teca (Tectona grandis). O experimento foi realizado em delineamento inteiramente casualizado, com os tratamentos: T1 – 100% solo (solo nativo); T2 - 100% substrato comercial (SC); T3 – 50% solo + 25% resíduo bovino (RB) + 25% resíduo de aves (RA); T4 – 50% solo + 25% RB + 25% resíduo suíno (RS); T5 – 25% SC + 25% solo + 10% RA + 20% RB + 20% RS; T6 – 25% SC + 25% solo + 10% RS + 20% RA + 20% RB; T7 – 25% SC + 25 % solo + 25% RS + 25% RB; T8 – 25% SC + 25 % solo + 25% RS + 25% RA. Ao final de 90 dias, foram obtidas informações a respeito das características morfológicas e características fisiológicas das mudas, verificando-se que, a condição do tratamento 8 foi a mais favorável porque permitiu a obtenção de mudas de melhor qualidade. Esse resultado foi influenciado pela taxa líquida fotossintética, condutância estomática e concentração intrínseca de CO2 das plantas, em condições adequadas. Palavras-chave: Tectona grandis.

Therefore, this study aimed to evaluate combinations between commercial substrate, soil, and different organic materials, and their effects on the growth and physiology of teak (Tectona grandis) seedlings. The experiment was carried out in a completely randomized design, with the treatments: T1 – 100% soil (S - native soil); T2 - 100% commercial substrate (SC); T3 – 50% soil + 25% bovine residue (RB) + 25% poultry residue (RA); T4 – 50% solo + 25% RB + 25% swine residue (RS); T5 – 25% SC + 25% solo + 10% RA + 20% RB + 20% RS; T6 – 25% SC + 25% solo + 10% RS + 20% RA + 20% RB; T7 – 25% SC + 25 % solo + 25% RS + 25% RB; T8 – 25% SC + 25 % solo + 25% RS + 25% RA. At the end of 90 days, information was obtained about the morphological and physiological characteristics of the seedlings, verifying that the condition of treatment 8 was the most favorable because it allowed the obtainment of quality seedlings. This result was influenced by the liquid photosynthetic rate, stomatal conductance and intrinsic CO2 concentration of the plants, under suitable conditions. Keywords: Tectona grandis.
