DESEMPENHO NO CAMPO DE MUDAS DE Eucalyptus urophylla, Eucalyptus camaldulensis E Corymbia citriodora PRODUZIDAS EM DIFERENTES RECIPIENTES

Performance in the field of Eucalyptus urophylla, Eucalyptus camaldulensis and Corymbia citriodora produced in different containers. We evaluated the production of Eucalyptus urophylla, E. camaldulensis and Corymbia citriodora in pressed blocks and two tubes models by the evaluation of survival and early growth of seedlings. We assessed survival at sixty days and initial growth in height and diameter at ground level to the tenth month after planting. We used a randomized block design with five replications. Seedlings of E. urophylla and E. camaldulensis produced in blocks, and in two tube models, and seedlings of C. citriodora produced in two tube models had high survival rates. On the other hand, seedlings of C. citriodora produced in blocks presented the lowest survival mean. The initial seedling growth mean of E. urophylla produced in blocks and tubes of 50 cm 3 were higher than for seedlings grown in tubes of 35 cm 3 . In relation to E. camaldulensis and C. citriodora the average initial growth were similar in the three containers. Production of seedlings of E. urophylla is recommended in tubes of 50 cm 3 or in compressed blocks, E. camaldulensis seedlings can be produced in three containers, and C. citriodora in tubes of 50 and 35 cm 3 .
