“…Since the work of Pires (1973), which proposed a classification for Amazonian plant formations, a little over 60 studies have been conducted in restingas in Pará, including abstracts, scientific articles, theses and dissertations. Some of these works focus on species aspects of the vegetation: floristics/phytosociology (Bastos 1996;Santos et al 2003;Silva et al 2010;Quaresma & Jardim 2015); relationships of plant communities and environmental factors (Jardim et al 2016;Silva et al 2018); and taxonomic groups (Vicente et al 1999;Rocha 2000;Rocha et al 2001a,b;Rocha & Bastos 2004;Rosário et al 2005;Margalho et al 2009;Sousa et al 2009;Barbosa et al 2013;Mesquita et al 2013;Abreu et al 2014;Lima et al 2014;Falcão-da-Silva et al 2015a, b;Schneider et al 2017). In addition, Bastos et al (2003) covers botanical and medicinal use aspects and a book by Bastos et al (2014) is about flowers and fruits that are part of the beauty of these environments.…”

Pará state has one of the longest coastal in Brazil. However, floristic surveys have been conducted in few regions and only one study has comprehensively evaluated the coastal flora of the state. The objective of this study was to create an updated and certified checklist of the angiosperms in the restingas of Pará. The list was made using literature, floristic and taxonomic revisions, herbaria specimens from HBRA, IAN, MFS and MG, and collections made between 2014 and 2018. Overall, 470 species, 279 genera and 92 families were recorded. Of this total, 11 species are new records for coastal Pará. The families with the greatest number of species are Fabaceae, Cyperaceae, Poaceae, Myrtaceae, Rubiaceae, Asteraceae, Apocynaceae, Polygalaceae, Convolvulaceae and Melastomataceae, which correspond to 52% of the species. Cyperus, Eugenia, Rhynchospora, Eleocharis and Ipomoea are the most representative genera. For life forms, herbs and shrubs are predominant. Dune fields, restinga forest and herbaceous swamp are the phytophysiognomies with the greatest number of species. A comparison with restingas of northeastern Brazil showed that the flora surveyed is most similar to that of Maranhão, since many species of the Amazonian flora also occur in restingas in this state.

“…Studies of phenotypic diversity among accessions were only found for garlic (Silva et al, 2014) and cocoa (Leal et al, 2008), no records of the use of this technique in lima beans and other important crops were found. The use of bidimensional scaling has been more common in the study of natural populations (Telles et al, 2001;Souza et al, 2015;Higuchi et al, 2018;Silva et al, 2018), in the construction of genetic linkage maps (Preedy & Hackett, 2016) and not frequent in plant breeding when using molecular data, such as studies of genetic distances between cultivars and varieties of lima bean (P. lunatus) and common bean (P. vulgaris) (Beebe et al, 1995;Nienhuis et al, 1995, Fuente et al, 2012. However, the routine of conventional breeding programs, are mainly based on phenotypic data based on qualitative and quantitative characters, and scaling may be highly applicable for studies of dispersion between accessions.…”

Studies about phenotypic diversity are common in germplasm banks. The inference about this variability must be realized through several methods. The multidimensional scaling is a multivariate technique that has not yet been well explored in plant breeding programs. The objective of this study was to evaluate the phenotypic dispersion of landrace lima bean varieties using the non-metric multidimensional scaling technique (nMDS) based on seed morphology. Seeds of 25 lima bean accessions were characterized based on the morphological descriptors proposed by the International Plant Genetic Resources Institute. Distance matrices between the accessions were estimated based on the qualitative and quantitative variables, in addition to simultaneous analysis of the qualitative and quantitative data, using the Mahalanobis and Gower distances. The distances were represented by non-metric multidimensional scaling. The adjustment level of the nMDS mapping was calculated using Kruskal’s Stress. The scaling based on the quantitative and mixed data was efficient to represent the distances of the lima bean accessions in the bidimensional plane presenting Stress less than 20%. Divergent accessions, such as 11, 13, 17 and 25 were identified. The inclusion of qualitative characters provided the best discrimination of the accessions, confirming the importance of the simultaneous character analysis. The nMDS must be used as a complementary technique to those commonly employed in studies of phenotypic diversity in lima beans.
