“…Knowledge of the morphology, growth habit, and data regarding biology of species are of fundamental importance to define strategies in breeding programs. Such practices aim at creating conditions favorable to plant development, and visual quality is an important criterion for consumers that look for plants with immediate decorative effects (GARBEZ et al, 2017;OLIVEIRA et al, 2017).…”

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.

“…The number of woody species traded by local nurseries made up 39% of the same found in native fragments of Cerrado and it may be insufficient to meet the demand of restoration plans for achieving rich and diverse plant communities. However, this scenario is better than the one found by Oliveira et al (2017), who evaluated the availability of native species saplings in nurseries settled in the Rio Grande catchment area, Minas Gerais (Brazil) and found a species richness lower than 10% compared to the regional native vegetation. Cerrado is the species-richest savanna in the world (Mendonça et al, 2008) and the relatively low species richness available in nurseries (39%) is attributed to difficulties in collecting seeds from a wide range of native species and the poor knowledge on germination and growth of many native plant species 19 -23 (Oliveira et al, 2016;Oliveira et al, 2017;Santos & Queiroz, 2011).…”

The main obstacles for plant sapling production of Brazilian native species are seed shortage (80%), difficulties in trading plant saplings (75%), and poor training for the management of native species (65%) (Silva et al, 2017).…”

Richness of Cerrado Woody Species Engaged in Ecological Restoration in the Brazilian Federal District

2020

This study has evaluated the richness of Cerrado woody species engaged in ecological restoration in the Brazilian Federal District (BFD). A survey gathered information on plant species traded by local nurseries, species recommended in restoration plans (PRADs), species effectively introduced in areas under restoration, and species present in preserved fragments of Cerrado. Results summed 566 Cerrado woody species from 80 botanical families of which 171 species were traded by local nurseries, 277 were recommended in PRADs, 190 were effectively used in restoration projects, and 434 species were sampled in fragments of native Cerrado. We found low similarity between species composition available in nurseries, recommended in PRADs, used in restoration projects and present in preserved fragments of native Cerrado. Such results indicate a poor connection between steps related to the selection of native woody species that make up initial plant communities on sites under ecological restoration.

“…Apesar da diversidade encontrada para o fragmento em processo de restauração ser baixo, podemos afirmar que a área em estudo está seguindo uma trajetória positiva quando comparado com a Matinha que tem um tamanho de área maior (5,72 ha) e um tempo maior de implantação. A baixa riqueza de espécies plantadas na área de restauração, podemos atribuir a baixa produção de espécies nativas produzidas nos viveiros da região (DE OLIVEIRA et al, 2017).…”

By monitoring and evaluating areas in the process of restoration, it is possible to monitor the evolution of the ecosystem as a whole and even make decisions in these areas. The objective of this work was to evaluate the attributes of the species composition, structure and functionality of the forest restoration process in a semideciduous seasonal Forest area at 8 years. The data for the arboreal vegetation were evaluated in total area, for soil cover in transects and for natural regeneration in plots. In the floristic survey of the arboreal stratum were recorded 257 individuals distributed in 19 species, being the Fabaceae family the one that presented the greatest richness of species; being Trema micranta the arboreal species with the highest value of basal area and of absolute density. The predominant ecological group was that of pioneer species with predominance of zoocoric dispersion. In the evaluation of the floristic composition of the natural regeneration, 54 individuals were found distributed in 19 genera and 13 families. The Shannon index (H ') found for the tree species was 2,375 and for the species of the regenerating stratum it was 2,584. In the soil cover the percentage of litter predominated. The attributes of the species composition, structure and functionality of the forest restoration process of this seasonal semideciduous forest, through the use of ecological indicators, suggest the efficiency of the restored area.
