Seedling Morphological Characteristics on Survival, Uniformity, and Growth during a Full Short Rotation in Eucalyptus grandis x E. urophylla Plantation

The objective of this work was to evaluate the losses in process, survival, uniformity and growth during an entire short rotation a clonal planting Eucalyptus grandis x urophylla Brazil as function different morphological characteristics seedlings considered proxy seedling quality. Seedlings were classified descending order quality by following treatments: A > B C. Treatment D composed prime 180 days old nursery. experienced mortality rate 3% 30 after planting, while C showed 8%. Throughout treatment had highest total 24%, which 15% higher than average other three treatments. seedlings, determined IQD, positively correlated with stem diameter, leaf biomass, PH50 at 60 age. However, these relationships lost significance later ages, DQI could not explain variation volume stand (PV50) along rotation. Despite early differences, from 36 64 months, only (Treat. D) difference wood
