“…9, No. 3; between fresh mass and dry mass, divided by fresh mass (Moura, 2010). We calculated the length/diameter ratio (C/D) of the fruits, regarding that the ratio C/D < 1 indicates flat shape, C/D > 1 is ovoid, and the ratio C/D = 1 means globose (Sacramento et al, 2003).…”

The genus Acrocomia (Arecaceae) is widely distributed in the Neotropics, without consensus on the number of species. The arboreal species are explored in their native countries. To subsidize better use of the observed variation in fruits of different species for product extraction, taxonomy, conservation and genetic improvement, our objective was to characterize biometrically the fruits and anatomically the mesocarp from natural populations of A. aculeata, A. intumescens and A. totai. We observed different colors of epicarp and mesocarp in A. aculeata and A. totai, while the fruits of A. intumescens were light green or yellowish. The fruits of A. aculeata showed diameter considered large (3.9-4.6 cm) and the highest dry mass (26.3-33.5 g), A. intumescens presented intermediate diameter (3.1-3.9 cm) and mass (11.5-18.8 g), and A. totai had the smallest diameter (2.2-3.0 cm) and mass (4.1-11.4 g). The morphoanatomical analysis of the mesocarp did not distinguish the three species. However, it revealed the presence of useful compounds for human consumption and with economic potential, such as oil in the parenchyma cells, mucilage, starch and phenolic compounds. We concluded that the mesocarp anatomy is not useful for taxonomy, but the biometric variation is, as well as variation within species can be applicable in conservation and genetic improvement.Keywords: biofuel, palm, plant anatomy, plant products, plant taxonomy ResumoO gênero Acrocomia (Arecaceae) é amplamente distribuído no continente americano não havendo consenso sobre o seu número de espécies, sendo as de porte arbóreo comercialmente exploradas nos países onde ocorrem. Com intuito de gerar subsídios para melhor aproveitar a variação observada nos frutos das diferentes espécies para taxonomia, conservação e melhoramento genético das espécies, o objetivo do presente estudo foi caracterizar biometricamente os frutos e anatomicamente o mesocarpo de populações naturais de A. aculeata, A. intumescens e A. totai. Foram observadas diferentes colorações de epicarpo e do mesocarpo em A. aculeata e A. totai, enquanto os frutos de A. intumescens são verde-claros ou amarelados. Os frutos de A. aculeata têm diâmetro considerado grande (3,9-4,6 cm) e de maior massa seca (26,3-33,5 g), A. intumescens apresentou diâmetro e massa intermediários dos seus frutos (3,1-3,9 cm e 11,5-18,8 g, respectivamente). A. totai apresentou os menores diâmetro e massa de frutos (2,2-3,0 cm e 4,1 -11,4 g, respectivamente). A análise morfoanatômica do mesocarpo não diferenciou as espécies do estudo. No entanto, revelou a presença de compostos úteis para consumo humano e potencial econômico dos compostos identificados, como a presença de óleo nas células do parênquima, mucilagem, amido e compostos fenólicos. Conclui-se que a anatomia do mesocarpo não é útil para taxonomia e que variação biométrica entre as espécies pode ser empregada para este fim, assim como a variação dentro das espécies pode ser útil para fins de conservação e melhoramento genético.

“…The morphometric characterization of seeds allows congeners to be differentiated (CRUZ; MARTINS; CARVALHO, 2001), and the dispersion form of the taxon and manner of seedling establishment to be identified (FENNER, 1993), as well as the tropical forest successional stage to which a species belongs (BASKIN; BASKIN, 1998). According to Moura et al (2010), biometric differences in fruit and their seeds are related to environmental factors, and to how a population behaves during establishment in a new environment, in particular when a species is widely distributed. However, in the present study of individuals from different areas, no biometric differences were observed in C. prunifera seeds, indicating both homogeneity of the species in relation to the factors evaluated and uniformity of the evaluated characteristics in responding to environmental factors.…”

Evaluation of Carnauba Progenies and Estimates of Genetic Parameters in the Juvenile Phase

Carnauba (Copernicia prunifera) is a forest species with multiple uses, and is of great economic and social importance for several communities involved in extractive agriculture in northeastern Brazil. However, there are few studies on genetic variability in this species. Thus, this work aimed to produce information about the genetic characterization of C. prunifera seeds and seedlings, using provenance and progeny evaluations. A progeny test was performed in a plant nursery, using seeds of 36 matrices sampled in the municipalities of Mossoró and Apodi (Rio Grande do Norte State), and Russas and Icapuí (Ceará State). Three groups were derived according to the spatial distance between the collected matrices. Biometric analyses of the seeds were performed, adopting a completely randomized experimental design, with four replicates of 25 seeds in each analysis. A randomized block design (five replicates and five plants per plot) was used at the seedling production phase. The data evaluated included the emergence speed index, emergence percentage, leaf size, leaf base diameter, and survival (at 30, 60, and 90 days after sowing). The restricted maximum likelihood method was used in the statistical analysis, with the aid of SELEGEN software. In order to evaluate genetic variability in the C. prunifera population samples, it was verified that the juvenile characters presented a moderate genetic control. The three groups of spatially delimited matrices presented no significant genetic differences. This information may assist in the development of forestry practice for this species.

“…Roveri Neto e Paula (2017) e Marzinek e Mourão (2003) em estudo com C. speciosa obtiveram médias menores do que a encontrada neste estudo para o comprimento do fruto (12,99 cm e 14,68 cm, respectivamente). Essa diferença pode estar relacionada a diversos fatores, entre eles, condições ambientais e origem genética do material estudado (MOURA et al, 2010 As estimativas dos coeficientes de correlação de Spearman (rS) entre as características biométricas de frutos e sementes de C. speciosa encontram-se na tabela 3, onde observou-se que a maior estimativa de correlação ocorreu entre a largura e a espessura do fruto (0,834). A variável massa do fruto (MFF) correlacionou de forma positiva e significativa com comprimento do fruto (CFR) e largura do fruto (LFR), indicando que quanto maior o tamanho do fruto (comprimento e largura) maior a massa do mesmo.…”

RESUMOCeiba speciosa (Malvaceae) é uma espécie arbórea nativa do Brasil, conhecida popularmente como paineira, apresenta importância econômica e ecológica. Objetivou-se neste estudo caracterizar biometricamente os frutos e sementes de C. speciosa ocorrentes no município de Alta Floresta, Mato Grosso. Foram amostrados 25 frutos provenientes de árvores distribuídas em fragmentos florestais. O comprimento do fruto variou de 22,30 a 35,00 cm, a largura de 63,50 a 97,27 cm, a espessura de 65,79 a 93,28 cm e massa de 287,15 a 958,85 g. O número médio de sementes por fruto foi de 141,72. Em relação ás sementes, o comprimento variou de 6,17 a 8,82 cm, a largura de 6,32 a 8,37 cm, a espessura de 5,82 a 8,37 cm e a massa de 35,00 a 121,35 g. O valor médio de massa de paina foi 39,78 g. Ceiba speciosa apresentou maior variabilidade quanto ás características massa do fruto, número de sementes por fruto, massa da paina e massa das sementes. Verificou-se correlação significativa entre a largura e a espessura do fruto; entre a massa e o comprimento e largura do fruto, e entre a massa da paina e massa das sementes, evidenciando forte associação entre as mesmas.
