“…The study of divergence performed by Tocher cluster analysis grouped the accessions through analysis of the descriptors evaluated in such a way that there was greater homogeneity within the group and a higher level of heterogeneity among the groups (CRUZ; REGAZZI; CARNEIRO, 2013;ROSA et al, 2019). Group I was formed by eight accessions that were similar in relation to the shape of the apex (caudate), shape of the leaf in the transversal section (elliptical), and rhizome color (orange).…”

Morphological Characterization and Genetic Diversity in Ornamental Specimens of the Genus Sansevieria

The aim of this study was to characterize and estimate genetic divergence among twelve specimens of the Sansevieria genus from the collection of the Universidade Federal do Piauí (UFPI). A completely randomized experimental design was used with three replicates, and the plot consisted of four plants. In morphological characterization, qualitative and quantitative descriptors of leaves were evaluated. Genetic divergence among the specimens was determined by the Tocher clustering method and the hierarchical UPGMA. There is genetic variation among specimens evaluated, which was also expressed by the variability of colors, shapes, and sizes of the leaves. The Tocher clustering method and the hierarchical UPGMA were effective in differentiation of the specimens from multi-categorical qualitative descriptors, as the Tocher method grouped the accessions in two groups and the UPGMA in seven different groups. We highlight the accessions SSV 09 and SSV 10 as exhibiting the highest mean values in weekly leaf growth and in leaf height, important characteristics for local sale and for export.

“…Cluster analysis (Unweighted Pair-Group Method Using Arithmetic Mean -UPGMA) and dispersion (principal components analysis -PCA) methods are examples of multivariate techniques used in the analysis of morphological data. UPGMA cluster analysis determined by Sneath and Sokal (1973) seeks to genetically discriminate individuals and allows them to be separated into groups by analyzing a set of characteristics inherent to each individual, so that there is homogeneity within the group and heterogeneity between groups (ROSA et al, 2019). Studies using the UPGMA method were carried out to identify variability among accessions of lima beans (GUIMARÃES et al, 2007;BRITO et al, 2020).…”

Selection of Superior Genotypes of Lima Bean Landraces by Multivariate Approach

et al. 2022

The knowledge of genetic diversity in plant population is essential to the success of plant breeding programs. Thus, previous characterization of landraces is one of the first steps before the indication of genotypes to these plant breeding programs. This study aimed to characterize, through morphological traits, and estimate the genetic diversity in landraces of lima bean (Phaseolus lunatus L.). Genetic diversity was estimated by using multivariate methods that selected individual landraces to be indicated for farmers and consumers. According to morphological traits proposed by Biodiversity International, the genotypes UFPI-667 and UFPI- 682 showed higher dissimilarity and high potential to be used in crosses since they are genetically distant and complementary. The principal component analysis identified positive and significant phenotypic associations between variables: pod length, pod width, and grain production. According to the multivariate methods used, the landraces UFPI-666, UFPI-650, UFPI-651, UFPI-687, UFPI-658, UFPI-673, UFPI-667, and UFPI-674 are potential candidates for selection since they have relevant features for lima bean breeding, such as shorter cycles and higher grain production. This study showed that multivariate analysis can be used as an effective tool to find potential traits in lima bean and can assist the lima bean breeders in the selection of potential landraces. Accessions UFPI-667 and UFPI-682 can be indicated as genitors for breeding programs, as they are genetically distant and complementary in their characteristics.

The species Lecythis pisonis (L. pisonis) popularly known as "sapucaia" or "cumbuca de macaco", is a plant belonging to the family Lecythidaceae. This family has interesting pharmacological activities that have driven researchers to explore their species. Observing the biological potential of the species L. pisonis, this work aimed to trace the chemical profile of its leaves and to evaluate the in vitro antioxidant (DPPH and ABTS •+) and cytotoxic activity against Artemia salina Leach larvae. Qualitative tests identified the presence of triterpenes, steroids, saponins, flavonoids, and phenolics in general. The phytochemical investigation of the leaves resulted in the identification of the mixture of triterpenes: epifriedelanol and friedelin (1+2), α-amyrin and β-amyrin (4+5), squalene (3) and ursolic acid (16); the mixture of steroids: stigmasterol and β-sitosterol (6+7); α-tocopherol (8); of the mixture of esters: methyl palmitate, ethyl palmitate, ethyl 9-octadecenoate, 9,12,15-methyl octadecanoate, butyl palmitate, ethyl octadecanoate and butyl octadecanoate (9-15); the mixture of isoquercitrin and astragalin flavonoids (20+21); gallic acid and methyl gallate (17+19); gallic acid (17) and ellagic acid (18). This the first report of the identification of substances 8-15, 17-21 in the leaves of the species L. pisonis. The evaluation of the antioxidant activity of polar extracts revealed a great antioxidant potential, which may be associated with high levels of phenols and total flavonoids. The quantification of proanthocyanidin in the extract in MeOH showed a content of 8.65 mg EC/g of crude extract. The bioassay carried out with A. salina MeOH and MeOH:H 2 O extracts showed mild toxicity. A espécie Lecythis pisonis (L. pisonis), conhecida popularmente como sapucaia ou cumbuca de macaco, é uma planta pertencente à família Lecythidaceae. Esta família possui atividades farmacológicas interessantes que têm impulsionado pesquisadores a explorar suas espécies. Observando o potencial biológico da espécie L. pisonis, este trabalho teve como objetivo traçar o perfil químico de suas folhas, avaliar a atividade antioxidante in vitro (DPPH e ABTS •+) e citotóxica contra larvas de Artemia salina Leach.
