Thermal Profile of Wood Species From the Brazilian Semi-Arid Region Submitted to Pyrolysis

Abstract

Thermal profile of wood species from the brazilian semi-arid region submitted to pyrolysis. CERNE, v. 25, n. 1, p. 44-53, 2019. HIGHLIGHTS We analyzed native and endangered species of the Brazilian semi-arid region. The thermal profile of the species was questioned for energy generation. Mimosa tenuiflora and Poincianella pyramidalis were the most suitable wood species for sustainable charcoal production. The energy characteristics will allow the efficient management of the species in mixed plantations for this purpose.

ULTRASOUND AND WATER IMMERSION TO PROMOTING VIGOR IN SEEDS AND SEEDLINGS OF Cnidoscolus quercifolius

“…P á g i n a | 73 entering the seeds due to the action of the porosity of the integument seeds (RIFNA et al, 2019). For the C. quercifolius seeds, the cerose coat that recover the tegument can be broken with this treatment, probably (DIAS JÚNIOR, et al, 2019). In general, Dry lands biome seeds respond well to immersion in water before sowing in according to Lima et al (2019).…”

“…Currently, there are some efforts to promote a sustainable production of forest essences from Caatinga biome, for example, studies in seedling formation (ANTUNES et al, 2014;ANDRADE et al, 2015;MENINO et al, 2015), bioecology (APGAUA et al, 2014), morphology (LOUREIRO et al, 2013), satellite analyses (SILVA et al, 2018), and thermal image (DIAS JÚNIOR, et al, 2019). However, for some species in Caatinga species have dormancy and this fact can be disturbing the forest production and this fact is poorly studied (Medeiros et al, 2005) or are recommendation the acid treatments to improve the germination to broken the seed resistance in Euphorbiaceae family (LOUREIRO et al, 2013).…”

“…The Euphorbiaceae family is an important taxon present in Caatinga biome area (APGAUA et al, 2014;ANDRADE et al, 2015;MENINO et al, 2015;DRUMOND et al, 2016;DIAS JÚNIOR, et al, 2019).…”

“…The seeds produced by this family there is a formation of lipoprotein caruncle and a tegument that protect the seeds from environmental factors, but that can allow the seeds to have a low germination and uniformity under commercial conditions (ANDRADE et al, 2005;LOUREIRO et al, 2013;MENINO et al, 2015;DRUMOND et al, 2016). An important example is Cnidoscolus quercifolius Pohl specie (DIAS JÚNIOR, et al, 2019).…”

“…The pharmaceutical industry has requested specimens of this species to produce medicines. For this reason, planting areas must be implemented to prevent them from being removed from nature, in an extractive way, the raw material for this sector (DIAS JÚNIOR, et al, 2019).…”
