1. Physiology of the forage cactus cultivate Opuntia stricta (Haw.) Haw under different irrigation frequencies in the Semiarid
ABSTRACT The objective of this work was to evaluate the physiological variables of the cultivar Opuntia stricta (Haw.) Haw in the first cycle and in the regrowth, under different frequencies of drip irrigation, cultivated in the Agreste da Paraíba mesoregion. Therefore, a randomized block design was used, with 2 treatments (irrigation frequencies) and 4 rep

2. Carbon Dots from Pilosocereus gounellei for Fluorimetric Determination of Tannin in Tea Using a Flow-Batch System
In this study, xiquexique (Pilosocereus gounellei) native endemic cactus from the Brazilian semiarid was used for the first time as a natural carbon source (“green precursor”) for the synthesis of highly fluorescent carbon dots (CDs). These CDs were successfully used to develop a fast, low-cost, eco-friendly fluorescence method for the determination of t

3. GERMINATION OF CACTUS SEEDS UNDER SALINE STRESS
RESUMO As sementes de cactáceas que ocorrem em florestas tropicais sazonais secas estão sujeitas a múltiplos estresses, a exemplo do estresse salino, que limita a embebição e, consequentemente a germinação. Assim, objetivou-se comparar o desempenho germinativo de sementes de Cereus jamacaru subsp. jamacaru e Pilosocereus pachycladus subsp. pernambucoe

4. ROOT DISTRIBUTION, NUTRIENT CONCENTRATION AND ACCUMULATION IN ‘GIGANTE’ CACTUS PEAR IRRIGATED WITH SALINE WATER
RESUMO Em regiões semiáridas com maior variabilidade climática, mais eventos de seca e retardo das estações chuvosas, a suplementação hídrica favorece a segurança produtiva do cultivo da palma forrageira. Objetivou-se avaliar a distribuição radicular, o teor e a exportação de nutrientes em palma forrageira ‘Gigante’ submetida a diferentes co

6. Nutrients in ‘Gigante’ forage cactus pear under different saline water irrigation depths and planting densities
RESUMO Variações climáticas tendem a aumentar a ocorrência de condições extremas de seca em ambientes semiáridos e isso pode comprometer o rendimento mesmo de culturas tolerantes como palma forrageira. A irrigação da palma com água salina têm possibilitado bons resultados, e sua combinação com modificações nas densidades de plantio pode reflet

7. Total phenolic acids and flavonoid contents determination in Yemeni honey of various floral sources: Folin-Ciocalteu and spectrophotometric approach
Abstract Twenty-nine Yemeni honey samples were analyzed to determine total phenolic and flavonoid contents using Folin-Ciocalteu and spectrophotometric technique. These tested honey samples were collected from different regions corresponding to various floral species: jujube, cactus and multifloral plants. Folin-Ciocalteu method was adopted for the analysis

10. Pollination biology of the endangered columnar cactus Cipocereus crassisepalus: a case of close relationship between plant and pollinator
ABSTRACT The family Cactaceae possesses considerable floral diversity and is exclusively zoophilic. Cipocereus crassisepalus is an endangered species of columnar cactus, whose floral characteristics fit the chiropterophily syndrome. This study aimed to assess the correspondence between floral traits and pollinators and whether the pollination system of C. cr

11. Flowering and pollination ecology of Cleistocactus baumannii (Cactaceae) in the Brazilian Chaco: pollinator dependence and floral larceny
ABSTRACT Cleistocactus baumannii is the only ornithophilous cactus species in the Brazilian Chaco. In addition, this species of Cactaceae invests heavily in flowering in the ecoregion. Such characteristics motivated us to evaluate the temporal availability of flowers in the context of its floral visitors. The reproductive system of C. baumannii, the number o

12. Characterization of Nanocellulose Obtained from Cereus Forbesii (a South American cactus)
Crystalline cellulose nanofibers are obtained from the bark of Cereus Forbesii, a cactus native to the arid areas of South America. The obtaining of cellulose nanofibers was carried out in several steps: pretreatment of the raw material, elimination of hemicellulose and lignin to obtain cellulose, and an acid hydrolysis of cellulose to obtain crystalline cel
