Pinus greggii has potential for inclusion in temperate zone breeding programs around the world as it is frost resistant and produces high yields for pulp production. This study estimates the genetic parameters for two P. greggii progeny tests established in Telêmaco Borba, Paraná, Brazil. We evaluated diameter at breast height (DBH) and total height (H) at seven and nine years of age. The narrow-sense heritability ( h i 2 ) ranged from 0.225 (H, 7 years) to 0.515 (H, 9 years). The genetic correlation was high for all traits, reaching up to 0.91 between traits and 0.94 between ages. In addition, the results show the presence of Genotype x Environment interaction, and as such, the most productive and stable progeny were identified based on the Harmonic Mean of the Relative Performance of Genetic Values (MHPRVG) values. These population has genetic materials that are superior in terms of both DBH and H compared to the control and to P. greggii materials analyzed internationally. Our results contribute to the literature by providing further genetic information on this species, while also demonstrating the implications of thinning for genetic gains and effective population size.

Acrocomia aculeata is a tropical palm tree native to Central and South America that has significant economic, social, and environmental potential. However, land encroachment due to the expansion of agribusiness, and other factors such as urban sprawl, have resulted in the fragmentation and destruction of its habitat, leading to the loss of genes and genotypes in A. aculeata populations. In this context, the objective of this study was to characterize the genetic variability of A. aculeata populations by estimating gene flow and effective population size using an approach based on coalescent theory. Four populations located in the municipalities of Teodoro Sampaio (TSI and TSII), Rosana (RA), and Amparo (AP) in São Paulo State, Brazil, were genotyped with nine microsatellite markers. Gene flow and effective population size were estimated using a coalescent-based Bayesian inference implemented in the MIGRATE-N software. The effective population size (Ne) was obtained considering an assumed mutation rate of 5 × 10−5. Gene flow (Nm) for pairwise populations ranged from 0.28 to 1.17, with higher levels of migration between the three geographically proximal locations (TSI, TSII, and RA). The estimates of effective population size (Ne) were 444, 835, 838, and 874 for AP, TSII, RA, and TSI, respectively, showing that the effects caused by genetic drift may be more pronounced when Ne is smaller. The coalescent-based results add to our understanding of A. aculeata population genetics and suggest that some traditional assessment methods may be ineffective in characterizing historical evolutionary processes.

As native tree species are often used for densification, enrichment and degraded areas recovery, a better understanding of the behavior of their seedlings in response to light exposure is needed. This study evaluates the growth and morphological behavior of five native forest species of the Brazilian Mixed Ombrophilous Forest under shading levels of 90%, 50%, and 0%. The species were measured for height to root collar diameter (RCD) ratio (H:D), leaf area (LA), Dickson’s quality index (DQI), and stem, leaf, and root biomass. The LA did not differ among the treatments for three species and did not differ among species in full sun. The results for H:D ratio, DQI, and biomass indicate better growth in treatments with greater light availability. The species are recommended to be used as follows: Cedro-vermelha in full sun; Tarumã-azeitona, Ingá-doce, and Ocotea-guaicá in varying environmental conditions; and Branquilho-bravo in 50% shade and full sun conditions.

AbstractForest companies prefer a coppice system as a silvicultural strategy owing to its economic and sustainability advantages compared to developing new plantations for second rotations. However, studies aiming to determine the selection of superior genetic material for this management strategy are scarce. In this study, we evaluated five clonal tests of Eucalyptus spp. located in Itatinga and Angatuba, São Paulo State, Brazil, to determine the genetic correlations and control of productivity for regrowth management in two rotations. The volume (m3) and survival of the Eucalyptus spp. clonal tests were determined for the two rotations at 5.5 years of age. The experiments were carried out in a randomized block design with six replicates, five plants per plot, and unbalanced treatments. The heritability in the normal scale (\\hat h_n^2) for the survival ranged from 0.056 to 0.11, the heritability in the broad sense (\\hat h_g^2) ranged from 0.205 to 0.334, and the genotypic correlation was positive and high (0.71-0.86), and statistically significant to the genetic means for the two rotations. The ranking of the best clones in the second rotation was similar (76 %) to their ranking in the first selection. Thus, for the evaluated material, there was no need for the second measurement to obtain accurate selection when managing a coppice system.

* Corresponding author: fbp.engflorestal@gmail.com Abstract The Pinus genus covers a wide variety of widely cultivated species due to adaptability, high growth and wood quality. Molecular markers have been used for many genetic analyses, and among them, the microsatellite markers (SSR) have several applications and can be found in chloroplast genome (cpDNA) as well as in nuclear genomes (ntDNA). The chloroplast microsatellites markers (cpSSR) can be used for gene flow analysis, identification of hybrids,clones, paternity tests, genetic diversity studies, phylogenetic analysis, among others. The work aimed to characterize the cpSSRs of Pinus species with cpDNA sequenced and deposited in NCBI (National Center for Biotechnology Information). In the twenty species of Pinus spp. studied, 1.542 cpSSRs were identified, with 86,45% of mononucleotide type, and the less frequent the penta(1.10%) and hexanucleotide (1.04%) types. Predominated cpSSRs in non-coding regions (intergenic). The results indicate presence of a wide range of cpSSR for Pinus spp., which can subsidize breeding programs of interesting species.

The aims of this research was to evaluate the influence of foliar architecture of mini-cuttings associated with biological fertilizer application kinds based on macronutrients, micronutrients and amino acids in the production of clonal seedlings of Eucalyptus benthamii. The study was conducted in a completely randomized design in a 2 x 5 factorial arrangement (two types of leaf architecture “full leaf” and “Christmas kind” type of mini-cuttings and five kinds of application of biological fertilizer), in which each treatment constituted of four replicates, containing thirty mini-cuttingss per replicate. The use of the biological fertilizer provided a rooting of 51.67 to 65% and a mean survival of the mini-cuttings of 68.42%. For a higher operating income, the leaf architecture of “full leaf” mini-leaves is considered to be more viable than “Christmas tree”.

AbstractIn this study, we isolate and analyse a new set of microsatellite loci for Cattleya walkeriana. Twenty-two primer pairs were screened for C. walkeriana (n = 32) and assessed for their transferability to Cattleya loddigesii (n = 12) and Cattleya nobilior (n = 06). All loci amplified for C. walkeriana; however, for C. loddigesii and C. nobilior, four and five primers, respectively, did not present amplification. The polymorphic loci presented between 2 and 13 alleles per locus for both C. walkeriana and C. loddigesii, with respective averages of 5.1 and 4.2. For C. nobilior, we found between two and five alleles per locus, with an average of 2.6. For C. walkeriana, observed heterozygosity varied from 0.100 to 0.966, whereas expected heterozygosity ranged from 0.097 to 0.900. The observed and expected heterozygosity for C. loddigesii and C. nobilior were also estimated. We found no significant linkage disequilibrium between any pair of loci, and evidence of null alleles at four loci (Cw16, Cw24, Cw30 and Cw31) for C. walkeriana. The combined power to exclude the first parent and combined non-exclusion probability of identity were 0.999 and 2.3 × 10−20, respectively. These new loci can be used in studies of germplasm resources, and assessments of genotypic and genetic diversity and population structure, thus improving the accuracy of such analyses and their applicability in the conservation and protection of these endangered species.

O uso de microrganismos com efeito de promotores de crescimento e enraizamento de plantas tem apresentando resultados promissores no desenvolvimento de mudas clonais. Assim, o objetivo do estudo foi avaliar o potencial de isolados de rizobactérias e residentes do filoplano na promoção de crescimento e enraizamento de miniestacas de Eucalyptus dunnii. O experimento foi conduzido no delineamento de blocos casualizados, em arranjo fatorial 4 x 4 x 3, sendo os fatores constituídos por quatro coletas, quatro isolados bacterianos e três métodos de aplicação. Foram avaliados o percentual de sobrevivência das miniestacas na saída da casa de vegetação, casa de sombra e área de pleno sol e, o enraizamento das miniestacas aos 90 dias de idade. A resposta na sobrevivência de mudas na casa de vegetação, sombra e área de pleno sol variaram de acordo com o isolado, forma de aplicação e período de realização da coleta. Não foi observado efeito significativo dos isolados bacterianos sobre o enraizamento das miniestacas. Os isolados bacterianos apresentaram ora efeito benéfico, ora ausência de efeito para a sobrevivência e enraizamento das miniestacas. Por ser o primeiro relato do uso de rizobactérias e residentes de filoplano na promoção de crescimento de E. dunnii há demanda de novos estudos para a confirmação da efetividade destes microrganismos.

Este trabalho teve como objetivos avaliar a influência de temperaturas de armazenamento dos frutos e de concentrações de sacarose na germinação in vitro de embriões zigóticos maduros de macaúba (Acrocomia aculeata (Jacq.) Lodd ex Mart.). Após a colheita, os frutos foram armazenados à temperatura ambiente (27 ± 2 ºC) ou em câmara fria (a 12-15 ºC). Decorrido esse período, os embriões foram isolados e, imediatamente, inoculados em meio básico MS (MURASHIGE; SKOOG, 1962) suplementado com 100 mg L-1 de mioinositol, 2 g L-1 de carvão ativado e 6,5 g L-1 de ágar Merck®. O experimento foi realizado em delineamento inteiramente casualizado, em esquema fatorial 2 x 6. Os tratamentos consistiram da combinação de duas condições de armazenamento dos frutos após a colheita (frutos armazenados à sombra, em temperatura ambiente (27 ± 2 ºC) ou em câmara fria a 12 - 15 ºC, na ausência de luz, durante 30 dias, e concentrações de sacarose no meio nutritivo (5, 10, 15, 20, 25 e 30 g L-1). Utilizaram-se cinco repetições por tratamento, cada uma composta por cinco explantes. Consideraram-se como fonte de explantes embriões zigóticos extraídos de frutos maduros. Após 90 dias, avaliaram-se a germinação de plântulas completas, os percentuais de plântulas viáveis ou normais, plântulas que emitiram apenas primórdios de raiz e plântulas hiper-hídricas. Observou-se maior percentual de germinação nos embriões isolados de frutos mantidos em temperatura ambiente. Menor porcentagem de plântulas com primórdios de raiz foi obtida para os frutos mantidos em câmara fria. O meio acrescido de sacarose a 30 g L-1 contribuiu para o desenvolvimento de plântulas viáveis ou normais.

Este trabalho teve como objetivo avaliar o enraizamento de miniestacas apicais, intermediárias e basais de Eucalyptus benthamii Maiden et Cambage. As miniestacas utilizadas foram coletadas de minicepas estabelecidas a partir de mudas de origem seminal. O experimento foi conduzido no delineamento inteiramente casualizado, em arranjo fatorial 4x3, sendo os fatores constituídos por quatro clones de E. benthamii (C50, C51, C52 e C53) e três tipos de miniestacas, confeccionadas das porções apical, intermediária e basal das brotações. Avaliou-se a sobrevivência e o enraizamento das mudas aos 45 dias de idade, em casa de sombra, e aos 90 dias em fase de pleno sol. Avaliou-se ainda a altura das mudas aos 90 dias de idade. Ao final das avaliações, o clone C52 se destacou dos demais em termos de sobrevivência, enraizamento e crescimento em altura. Na fase de pleno sol, quando as mudas já haviam completado o ciclo de desenvolvimento, a miniestaca apical comprovou ser o tipo de propágulo com maior aptidão ao enraizamento entre todos os clones avaliados.AbstractRooting of apical, intermediate and basal minicuttings in clones of Eucalyptus benthamii. This study aimed to evaluate the rooting of apical, intermediate and basal ministumps of Eucalyptus benthamii Maiden et Cambage. The minicuttings were collected from ministumps originated from seedlings. The experiment was conducted in a completely randomized design, in a 4x3 factorial arrangement with factors consisting of four clones of E. benthamii (C50, C51, C52 e C53) and three types of cuttings (apical, intermediate and basal). The survival and rooting were evaluated with 45 days in shadow house, and 90 days in the full sun stage. In the end of the evaluations, the clone C52 proved to be better in survival, rooting and height growth. In full sun stage, when the seedlings completed the development cycle, the apical minicutting proved to be the kind of propagules with grater aptitude on rooting when compared with the others clones.Keywords: Minicutting; types of cuttings; clonal propagation.

Este trabalho teve como objetivo avaliar a sobrevivência e o crescimento durante a etapa de aclimatização ex vitro de mudas de dois clones de Eucalyptus urophylla x E. grandis obtidas pela técnica de enxertia in vitro. Para a obtenção das plantas enxertadas, foram utilizados porta-enxertos oriundos de plântulas de Eucalyptus grandis e E. urophylla germinadas in vitro e, como enxertos, ápices caulinares de dois clones de Eucalyptus urophylla x E. grandis micropropagados. Após 50 dias de cultivo in vitro, as plantas foram transferidas para as condições ex vitro, avaliando-se a sobrevivência e o crescimento em altura das mudas. Elevados índices de sobrevivência dos enxertos (87%) foram observados aos 70 dias na condição ex vitro, assim como adequado vigor no crescimento em altura. Notou-se comportamento semelhante entre os clones, em relação aos porta-enxertos utilizados, indicando que o processo de aclimatização adotado mostrou-se eficiente.

O objetivo deste trabalho foi avaliar a eficiência da enxertia in vitro na propagação de dois clones híbridos de Eucalyptus urophylla e E. grandis. Foram utilizados porta-enxertos juvenis obtidos de sementes de E. grandis e E. urophylla germinadas in vitro. As plantas enxertadas apresentaram pegamento de até 93% aos 50 dias de idade para as combinações de enxerto e porta-enxerto. Quanto ao crescimento em altura, verificaram-se melhores resultados em relação ao porta-enxerto E. urophylla. A análise histológica das plantas enxertadas comprovou a eficiência do processo de cicatrização do calo formado na região de conexão, seguida da reconstituição vascular.
