| Descrição: | The quality of conilon coffee seedlings produced is influenced by genetic variability among clones, the time of cutting collection, and the low concentration of endogenous auxin. The objective of this study was to evaluate the quality of seedlings of five conilon coffee genotypes produced by vegetative propagation through orthotropic branches (cuttings) with different concentrations of auxin (indole-3-butyric acid - IBA) and different times of cutting collection. The experiment was conducted in a nursery in the municipality of Linhares, Espírito Santo state, Brazil, in a randomized block design. The experiment consisted of five conilon coffee genotypes (A1, LB1, 143, 02, and 748) and concentrations of indole-3-butyric acid (IBA: 0, 500, 1000, 1500, and 2000 mg L⁻¹) and two cutting collection periods, summer (December) and winter (June). The cutting collection period played a crucial role in seedling bud formation, with cuttings collected in winter (June) showing a 72% reduction in bud formation in genotype 748. Genotype 143 exhibited limited bud development, regardless of the collection period. IBA was effective in improving the performance of cuttings collected in summer, especially at a dose of 959 mg L⁻¹. The results demonstrate the importance of the conilon coffee genotype and the cutting collection period in seedling quality. Furthermore, the proper use of IBA can be an advantageous strategy to promote seedling growth, especially for genotypes with lower vigor |
