Ciência Rural , 1997, DOI: 10.1590/S0103-84781997000200009
Abstract: the wood anatomy of mimosa trachycarpa benth. is described. photomicrographs as well as quantitative and stereological data of its minute structure were furnished. very fine rays, paratracheal parenchyma, libriform and not septated fibres, vestured pits and pores in clusters, tending to a diagonal pattern, were found. the wood anatomy was checked with literature of the leguminosae family and genus mimosa, considering its phylogenetical, taxonomical and ecological aspects.

Abstract: This work aimed to compare the diffusion of CCB preservative in bracatinga (Mimosa scabrella Benth.) and Eucalyptus viminalis Lab. round fence posts when exposed to dip-diffusion method. The pieces were submitted to the concentration of 2; 3.5 and 5% of active ingredients of “Osmose CCB” commercial preservative, during 2, 5 and 8 days. The penetration was analyzed in six positions in the pieces and the retention in three positions in the disks taken in ground contact area in the fence posts fitted out. The increase of treatment time and preservative concentration provided significant gains on penetration and retention of CCB for both tree species. In the work conditions, the eucalypt fence posts showed better response to the treatment.

Abstract: mimosa caesalpiniaefolia benth. is a native species from northeast region, brazil, which is cultivated progressively from maranh?o to rio de janeiro states. its presents great potential for arborization, it surrounds it lives and wood production. the present work was realizated with mimosa caesalpiniaefolia seeds with the objective to determine the substratum type, temperature, the middle time and the relative frequency of germination, for use as a pattern in the conduction of germination and vigor tests. it took place an experiment in the laboratório de análise de sementes do cca-ufpb, in areia-pb, in completely randomized design with the treatments distributed in outline factorial 4x4, temperatures (constant of 20, 25 and 30oc and alternate of 20-30oc) and substrate (seeds cowered by paper shits, seeds on paper sheets, seeds into sand and seeds into vermiculite) in four replications of 25 seeds. the following parameters were analyzed: germination and of abnormal seedlings (%) first germination count, germination speed, medium time and relative frequency of germination, fresh matter and weight of dry matter of seedlings. according the results in all substrates the temperature of 25oc was most adequate for conduction of germination and vigor tests for mimosa caesalpiniaefolia seeds. for all temperatures utilized the best germination was observed when the seed were sowed covered bay paper shits.
Estudo comparativo da madeira de Mimosa ophthalmocentra Mart. ex Benth e Mimosa tenuiflora (Willd.) Poir. (Fabaceae-Mimosoideae) na caatinga nordestina

Abstract: due to the economic importance of the wood of mimosa l. species in northeastern brazil's caatinga and to the fact that mimosa ophtalmocentra mart. ex benth. ("jurema-de-imbira") is confused with mimosa tenuiflora (willd.) poir. ("jurema-preta") and vice versa, this research aimed to present new data related to the anatomy and basic density of the wood of both species; to contribute to the taxonomic study for differentiating them; to identify anatomical characters of the wood relating them to the caatinga environment; and to present the energetic potential that they possess. the anatomical study and wood density determination were carried out with samples at dbh level and with two branches of individuals within the municipalities of serra talhada and sertania (pernambuco). the species both differed in bark type, color of heartwood and sapwood, besides the different anatomical characteristics found in the wood. mimosa ophtalmocentra has distinct growth layers consisting of parenchyma lines containing crystals, scarce parenchyma and smaller quantity of rays. mimosa tenuiflora, on the other hand, also has growth layers, but without crystals, axial parenchyma vasicentric, confluent and in bands, and greater percentage of rays. both species have some wood elements with anatomical characteristics typical of representatives of mimosa, contributing therefore to a better taxonomic understanding of the genus. based on wood anatomical parameters and elevated basic density (> 0.84 g/cm3), the conclusion was reached that both species have great perspectives for the production of fuel alcohol and charcoal since juvenile wood age. because mimosa ophthalmocentra has scarce parenchyma and fewer rays, it shows greater energetic potential than mimosa tenuiflora.

Abstract: the objective of this research was to study the dormancy of mimosa caesalpiniifolia benth. seeds during the maturation process. the seeds and fruits were collected from plants in a locality called engenho bujari, city of areia, state of paraíba, brasil. seed harvest extended from the 105th day after anthesis (d.a.a.) to the 210th (d.a.a.), from august 9 to november 22, 2001. the parameters evaluated were germination %, dormancy (%), vigor expressed by the first germination (%), seedling length, and seedling fresh and dry weight. it is concluded that to avoid seed dormancy in this species the collection must be done 154 d.a.a., when germination and accumulation of dry mass is maximum.

Abstract: The present study assessed the effects of different substrates on the emergence and initial development of Mimosa caesalpiniifolia Benth seedlings. For this purpose an experiment was done in a greenhouse of the Department of Plant Sciences of Universidade Federal Rural do Semi-árido (UFERSA), Mossoró-RN. The statistical design was completely randomized (CRD), where treatments were composed of nine substrates (T1: vermiculite, T2: coconut fiber, T3: trade hortimix , T4: vermiculite, coconut fiber and compost (1: 1:1), T5: coconut fiber and compost (1:1), T6: coconut fiber and compost (1:2),T7: vermiculite and compost (1:1), T8, vermiculite and compost organic (1:2) and T9: organic compost). All treatments were represented by four replications containing 25 seeds. The following variables were evaluated: emergency percentage, emergence rate index, length of shoot and root, stem diameter, dry leaves, stem, root and total leaf area, specific leaf area, leaf area ratio, and leaf weight ratio. Data were submitted to the Tukey test at 5% probability. The coconut fiber substrates, commercial hortimix and vermiculite proved superior promoted good emergence and early development of seedlings. The mixture of vermiculite, coconut fiber and compost (1:1:1), coconut fiber and compost (1:1), coconut fiber and compost (1:2) and organic compost and vermiculite (1: 1) was not shown to be adequate for the cultivation of seedlings. There was no emergency in the pure organic compound in the mixture of compost and vermiculite (1:2).Key words - Vermiculite. Organic compost. Coconut fiber. Sabiá. Substrates. = Objetivou-se com o presente trabalho avaliar o efeito de diferentes substratos na emergência e desenvolvimento inicial de plantulas de sabiá (Mimosa caesalpiniifolia Benth.). Para isso, foi instalado um experimento em casa de vegeta o do Departamento de Ciências Vegetais da Universidade Federal Rural do Semi-árido (UFERSA), Mossoró-RN. O delineamento estatístico utilizado foi inteiramente casualizado (DIC) e os tratamentos foram compostos por nove substratos (T1: vermiculita; T2: fibra de coco; T3: comercial hortimix ; T4: vermiculita, fibra de coco e composto organico (1:1:1); T5: fibra de coco e composto organico (1:1); T6: fibra de coco e composto organico (1:2); T7: vermiculita e composto organico (1:1); T8:vermiculita e composto organico (1:2) e T9: composto organico), com quatro repeti es de 25 sementes. As variáveis avaliadas foram: porcentagem de emergência; índice de velocidade de emergência; comprimento de parte aérea e de raiz; diametro do colo; matéria seca

Abstract: mimosa scabrella (mimosa scabrella benth.) is a multiple use forest species, typical from a mixed ombrophilous forest, asscociate to atlantic forest biome. the objective of this study was to compare structure, vegetal diversity and occurrence of mimosa scabrella among managed mimosa scabrella woods and forest formations. forest inventories were conducted in 45 plots (400- m2 plots), at different ages, and 40 secondary forest areas at different stages of natural succession (200 m2 plots). the results show that there are different patterns in the demographic structure of mimosa scabrella and species diversity between the bracatingais and secondary forests, particularly in the early years of both communities development. the significant difference in those patterns characterize the bracatingais as managed landscapes, which are strongly dependent on human action for its formation and maintanance.
