“…Em condições específicas como em ambientes tropicais, pode ocorrer estresses bióticos e/ou abióticos que podem diminuir a viabilidade do plantio de diversas espécies de alto potencial produtivo, sendo necessário a estratificação ambiental (Silva et al 2017). Nas espécies de eucalipto há uma classificação quanto a adaptação aos estresses e nessa classificação a produtividade é inversamente proporcional à tolerância adaptativa da espécie (Florence 2004).…”

“…Such survival rates are considered high, and they indicated that the experiments were properly conducted and there was a good adaptation of the clones, as observed in other clonal tests with Eucalyptus sp. (Silva et al 2017, Amâncio et al 2020).…”

Eucalyptus plantations in Brazil are expanding toward the northern and mid-western regions of the country. The objective of the present study was to select clones adapted to the local conditions, with a focus on the Cerrado region. Three clonal experiments were conducted in the municipalities of Catalão, Corumbá-de-Goiás, and Luziânia, in Goiás State, with 109 genotypes of eucalypts. The experimental design consisted of a randomized complete block design with single-tree plots and 29 blocks. Diameter at breast height and total height of all trees were measured four years after planting, for use in the estimation of wood volume for each genotype. The genotype × environmental interaction was significant and predominantly (74%) complex. The genotypic correlation among environments was moderate (< 0.47), indicating that clones should be selected for specific sites. However, some clones performed relatively well across all environments, such as clones CCL21, CCL30, AEC144, CCL07, and CCL35.

“…Species of the genus Corymbia have growth potential under several Brazilian climatic conditions. However, their potential has only been explored recently (Silva et al 2017, Tambarussi et al 2018, Araujo et al 2021. Diversification of species and genera for commercial planting is a way to reduce plantation vulnerability to biotic and abiotic stresses.…”

The objective of this study was to establish populations to start the breeding program of three species of Corymbia that are not widely planted in Brazil yet. To this end, basic density, bark content and growth of seedlots/provenances were evaluated three years after planting. The experiments consisted of 14 treatments for Corymbia citriodora subsp. variegata (CCV), 15 for C. maculata (CM), and five for C. henryi (CH). The species exhibited high survival, indicating adaptation to the Cwa climate while average coefficients of determination of seedlots exhibited intermediate values. The CCV from the Richmond Range (28º 55' S) exhibited the highest productivity. The mean annual increment was low (22 to 26 m 3 ha -1 ), but the basic density (573 to 613 kg m -³) was high compared to the standard for eucalypts in Brazil. The bark content was close to 15% and varied between and within species.
