Field studies of the inselberg flora north-eastern Brazil have resulted in discovery much greater morphological diversity genus Ameroglossum, than previously envisaged. These enigmatic plants are endemic to isolated rock outcrops, which long been surrounded by unsuitable habitat. The forms geographically and stable cultivation when grown under similar conditions. We here provide detailed descriptions two known species propose an additional seven new genus. A taxonomic revision genus,...
Pepper ( Capsicum L.) is a major vegetable and spice crop worldwide. Global production of both fresh dried fruit continues to increase steadily in terms area harvested yield. Various topics are addressed this review, including recent additions clarification taxonomy, genetic resources , cytogenetic studies, the current status our understanding mechanisms affecting biosynthesis capsaicinoids, use gene mutations elucidate carotenoid biosynthetic pathways their regulation, advances whole-genome...
ABSTRACT Spondias tuberosa fruits are extractively exploited and its use viability is dependent on factors such as occurrence, ripening, maturity at harvest, which influence quality contribute to increased perishability. This study evaluates the physiology changes during maturation of umbuzeiro genotypes from states Paraiba Pernambuco. Fruits 16 were harvested three stages in municipalities Casserengue-PB Brejo da Madre de Deus-PE. The experiment was conducted using a completely randomized...
Cactus pear var. miúda (Nopalea cochenillifera L. Salm-Dyck) is an important crop for the Northeast region of Brazil, composing one main sources animal feed. By April 2021, cladode rot caused death several cactus plants in a production area located Itaporanga, Paraíba state, Brazil (7°21'55.35" S and 38°11'38.68" W). The infected cladodes showed brown circular necrotic spots, soft with perforations that extended throughout cladode, followed by tipping over plants. incidence disease ranged...
Cactaceae species are karyotypically well-known with x = 11 and chromosome number variation due mainly to polyploidization. However, both assumptions based on descriptive observations without taking an evolutionary framework of into account. Aiming confirm these hypotheses in context, we obtained numbers for 20 Cactoideae, performed extensive review the family, analyzed data using a phylogenetic approach. The karyotypes presented here were characterized by CMA/DAPI banding, six 5S 45S rDNA...
This study aimed to assess the effects of convective drying at different temperatures (50, 60, and 70 °C) on technological chemical properties Pereskia sp. leaf powders identify most accurate mathematical model for describing their kinetics. Drying kinetics were modeled using four models: Henderson Pabis, Lewis, Logarithmic, Page. The Page Logarithmic models provided best fit both species, with high coefficients determination (R2 > 0.98) low MSE χ2 values, indicating suitability behavior...
The aim of this study was to evaluate the potential effects administering mangaba powder on liver function and somatic, oxidative lipid metabolism parameters in rats fed a high-fat diet. Prepared has important amounts phenolic compounds, vitamin C, dietary fiber oligosaccharides. A total 32 adult Wistar were initially randomized into two groups for biological assay: normal-fat (NF, n = 16) (HF, diets 21 days. These subsequently subdivided four groups: NF (n 8), HF diet with administration...
Abstract Mandacaru is a cactus with great socioeconomic potential, but lack of information about its cultivation hinders domestication. Here, we aimed to evaluate the acclimatization and vegetative development mandacaru under different substrates irrigation levels. For this, seeds inoculated in vitro were grown for 120 days, being transplanted pots containing four types substrate (S1—caatinga soil + gravel; S2—washed sand organic matter charcoal; S3—washed cattle manure sand; S4—commercial...

Two new species and one nothospecies of Tacinga from semi-arid Eastern Brazil are described. The taxa were discovered on the basis material collected during field trips carried out by staff Cactarium Guimarães Duque Instituto Nacional do Semiárido. A morphologic comparison all currently known, together with cytogenetic analysis taxa, made. Full descriptions, illustrations, taxonomic discussions for three given as well an identification key known species. IUCN categories assessed, resulting...
Abstract: We present the first listing of odonatan species (Insecta: Odonata) that occur in state Paraíba, Brazil. There are 49 and 29 genera registered, making Paraíba third number among Brazilian states northeastern region. The families with largest were Libellulidae, 31 15 genera, followed by Coenagrionidae 11 7 genera. Interior regions under-sampled, which should still lead to an underestimated species. In addition, we taxonomic notes two collected during our expeditions: males...
ABSTRACT This study aimed to characterize and select silk blossom genotypes (Calotropis procera) with forage potential. Between April July 2014, we cultivated 89 in plastic tubes arranged a randomized block design three replications; each experimental plot was composed of 8 plants. The following characteristics were evaluated: plant height (PH), stem diameter (SD), number leaves (NL), total leaf area (TLA), fresh mass (LFM), (SFM), root (RFM), dry (LDM), (SDM), (RDM). Significant differences...
During field studies of the inselbergs northeastern Brazil, two potentially new species were discovered. They share morphological characters with several genera Linderniaceae (Lamiales) such as Ameroglossum, Cubitanthus and Stemodiopsis, but differences are that they do not make a good fit any known in Linderniaceae. most likely related to like members this genus plants have conserved chromosome number 2n = 60. Their exclusive occurrence on Brazil also hint at relationship, because their...
Forage palms of the species Nopalea cochenillifera Salm-Dyck are an important source food for animals in semi-arid region. The aim was to evaluate best methods breaking dormancy seeds from accessions Salm-Dyck. treatments were: immersion sulphuric acid 3 minutes (T1), mechanical scarification with 80º sandpaper (T2); water at 80ºC 1 and (T3 T4 respectively) control (T5) - intact seeds. results showed that A2, A4 A5 did not differ each other or evaluated. However, access A3 obtained emergence...

For research, we selected studies with low implementation costs and advanced development implementation. This study identified leather footwear, textile, metallic non-metallic mineral extraction food beverage industries. search was carried out scientific databases Scopus Web...
Forage cactus (Opuntia spp. and Nopalea spp.) have great potential for animal feed human consumption due to their adaptability semi-arid conditions. This study evaluated six accessions of N. cochenillifera, analyzing pollen viability, stigma receptivity reproduction mode. Four types pollination were tested: spontaneous self-pollination, manual natural cross-pollination. The results indicated high viability in some during flower bud development, allowing self-pollination controlled...
