Caracterização morfológica do ramo, sementes e plântulas de matayba guianensis Aubl. e produção de mudas em diferentes recipientes e substratos

Matayba guianensis Aubl . is a shrubby or arborial Sapindaceae quite common in the Brazilian Cerrado with a key role in providing resources for ants and bees. It presents a rapid growth, and is important for the recovery of degraded areas, but little is known about its seedlings production. Therefore, the aim of this study was to describe the morphology of the branch and the seed germination and of seedling Matayba guianensis Aubl . in its post-seminal development and define the type of substrate and container suitable for seedling emergence and seedling production of this species. We evaluated three types of containers: black polyethylene bags, cartridge and polystyrene tray, with 5 kinds of substrates: sand, earth, earth - sand - manure (1:1:1); commercial substrate, and coconut fiber, with 4 replicates of 25 seeds per treatment . The branch, fruit, seed, seedling and their morphological events were described. The branch is cylindrical with paripinnate and alternate leaves, the fruit is dry and dehiscent. The seeds have a large amount of aryl, and the germination is cryptocotylar and hypogeal. The highest percentage of emergence occurred in styrofoam container with 91 % of the seeds germinated in commercial substrate , followed by coconut fiber (88 %). The development of root and stem were higher in tubes and plastic bags , using coconut fiber or commercial substrate.

Riqueza e composição de espécies de formigas no processo de recuperação de uma voçoroca

This study aimed to determine how the richness and composition of ant species behaves with changes in the recovery process of a gully erosion. The study area has 0.9 hectares subdivided into three sections called sector: A, B and C. For the definition of the sectors, erosive and natural restoring were taken as the base level of activity. Four transects were laid systematically throughout the area and surrounding compound with forest and grassland. Each transect had three pitfall trap ten meters apart from each other, with catches of ants were held in rainy and dry seasons. Analysis of variance was applied to compare the number of ant species per plot captured and Scott-Knott test 5% for comparison of means. To verify the similarity of species between environments it was performed an analysis of similarity (ANOSIM) and ordering of environments a Nonmetric Multidimensional Scaling (NMDS). We captured 74 species of ants inside and around the gully erosion. The more degraded environment and initial stage of regeneration, showed greater richness of ant species. The composition of ant species was different between the recovery environments and around. The parameters of ant communities analyzed, richness and composition species were influenced by the regeneration of the area, indicating that ants can be used as bioindicators of gullies recovery.
