“…Sagar et al (2014) found lower values than the current study, 89.1% of antioxidant activity in fruits of mature acerola (red colour) produced in India. Similar to current work Adriano et al (2011) reported levels of 810.2 ± 53.3 mg of ascorbic acid 100 g -1 of pulp in Olivier ripe fruit. Higher levels, 3,629.6 mg of ascorbic acid 100 g -1 of pulp were found by Figueiredo Neto et al (2014), in mature fruits of Okinawa.…”

The increased consumption of acerola in Brazil was triggered because it is considered as a functional food mainly for its high ascorbic acid content, but the fruit also has high nutritional value, high levels of phenolic compounds, total antioxidant activity, anthocyanins and carotenoids in its composition. The objective was to evaluate the chemical, physical-chemical and antioxidant activity of eight varieties of acerola tree. The acerolas used in the research were the harvest 2015, 8 varieties: BRS 235 -Apodi, Mirandópolis, Waldy -CATI 30, BRS 238 -Frutacor, Okinawa, BRS 236 -Cereja, Olivier and BRS 237 -Roxinha, from the Active Bank Germplasm APTA Regional Alta Paulista in Adamantina -SP. Avaluated the following attributes: pH, titratable acidity, soluble solids, reducing sugar, instrumental color, ascorbic acid, total phenolics, flavonoids and antioxidant activity. The design was completely randomized, 8 varieties and 3 replications of 20 fruits each. Acerola fruit of the analyzed varieties prove to be good sources of phenolic compounds and antioxidant activity, ensuring its excellent nutritional quality relative to combat free radicals. The variety BRS 236 -Cereja presents higher ascorbic acid content, antioxidant activity and phenolic compounds, and the lowest value for flavonoid, which was higher than the other cultivars, especially Olivier and Waldy CATI-30.

ResumoO aumento do consumo de acerola no Brasil foi desencadeado por ser considerada como alimento funcional principalmente por seus altos teores de ácido ascórbico, mas o fruto também apresenta alto valor nutritivo, elevado teores de compostos fenólicos, atividade antioxidante total, antocianinas e carotenoides em sua composição. O objetivo do trabalho foi avaliar as características químicas, físico-químicas e atividade antioxidante de oito cultivares de aceroleira. As acerolas utilizadas na pesquisa foram da safra 2015, de 8 cultivares: BRS 235 -Apodi, Mirandópolis, Waldy -CATI 30, BRS 238 -Frutacor, Okinawa, BRS 236 -Cereja, Olivier e BRS 237 -Roxinha, proveniente do Banco Ativo

“…West Indian cherry (Malpighia emarginata) fruits are known for their pleasant taste, high contents of vitamin C, vitamin A, B-complex vitamins, iron, calcium (SÁ et al, 2017), anthocyanins and carotenoids, compounds which have beneficial effects on human health for their known antioxidant action (MACIEL et al, 2010). The crop is adapted to the most diverse climates and can be found in several regions of the planet, but its commercial cultivation is concentrated in tropical and subtropical regions (ADRIANO et al, 2011), such as those found in the Brazilian territory.…”

Gas Exchanges, Quantum Yield and Photosynthetic Pigments of West Indian Cherry Under Salt Stress and Potassium Fertilization

et al. 2019

Water resources in the semi-arid region of Northeast Brazil commonly contain high salt concentrations, compromising the quality of water for agriculture. Thus, adopting techniques that make the use of these resources feasible in agriculture is fundamental. The present study aimed to evaluate the gas exchanges, quantum yield and photosynthetic pigments of grafted West Indian cherry subjected to salt stress and potassium fertilization under greenhouse conditions in the municipality of Campina Grande, PB, Brazil. Treatments were distributed in randomized blocks, composed of two levels of electrical conductivity -ECw (0.8 and 3.8 dS m -1 ) of water and four doses of potassium (50, 75, 100 and 125% of the dose recommended for the crop), with three replicates. The dose relative to 100% corresponded to 19.8 g of K 2 O per plant. Gas exchanges, chlorophyll a fluorescence and photosynthetic pigments of West Indian cherry are negatively affected by irrigation using water with electrical conductivity of 3.8 dS m -1 , which compromises the photosynthetic apparatus of the plant, a situation evidenced by the reduction in photosystem II quantum efficiency. Increasing potassium doses led to increments in transpiration, chlorophyll a maximum fluorescence and chlorophyll b content in West Indian cherry grown under salt stress, but do not attenuate the negative effects of irrigation with 3.8 dS m -1 water on its potential photochemical efficiency.Keywords: Malpighia emarginata.

TROCAS GASOSAS, RENDIMENTO QUÂNTICO E PIGMENTOS FOTOSSINTÉTICOS DA ACEROLEIRA SOB ESTRESSE SALINO E ADUBAÇÃO POTÁSSICARESUMO -Os recursos hídricos da região semiárida do Nordeste Brasileiro comumente possuem elevadas concentrações de sais, comprometendo a qualidade da água para agricultura. Desta forma, a adoção de práticas de manejo que viabilizem o uso de tais recursos na agricultura é fundamental. Neste trabalho, objetivou-se avaliar as trocas gasosas, o rendimento quântico e os pigmentos fotossintéticos da acerola enxertada submetida ao estresse salino e adubação potássica em condição de casa de vegetação no município de Campina Grande-PB. Os tratamentos foram distribuídos em blocos casualizados, sendo constituídos de dois níveis de condutividade elétrica da água -CEa (0,8 e 3,8 dS m -1 ) e quatro doses de potássio (50, 75; 100 e 125% da dose recomendada para a cultura), com três repetições. A dose de 100% correspondeu a 19,8 g de K 2 O por planta. As trocas gasosas a fluorescência da clorofila a e os pigmentos fotossintéticos da aceroleira são afetados negativamente pela irrigação com água de condutividade elétrica de 3,8 dS m -1 que compromete o aparato fotossintético da planta, situação observada através da redução da eficiência quântica do fotossistema II. As doses de potássio crescentes promovem incremento na taxa de transpiração, fluorescência máxima da clorofila a e no teor de clorofila b da aceroleira cultivada sob estresse salino, porém não atenuam os efeitos negativos da irrigação com água de 3,8 dS m -1 sobre a...

Agricultural exploitation in the semi-arid region of Northeast Brazil depends on the use of irrigation to guarantee safe production of crops. Nevertheless, the waters commonly used in this region have high levels of salts and require management strategies that make their use possible in agriculture. In this context, the present study aimed to evaluate water relations, photosynthetic pigments and growth of grafted West Indian cherry as a function of saline water irrigation and potassium (K) fertilization. The study was conducted under greenhouse conditions in lysimeters filled with eutrophic Regolithic Neosol with sandy loam texture, in the municipality of Campina Grande-PB, Brazil. Treatments were distributed in randomized blocks and consisted of two factors: two levels of irrigation water electrical conductivity -ECw (0.8 and 3.8 dS m -1 ) and four K doses (50, 75; 100 and 125% of the recommendation), with three replicates and one plant per plot. The 100% dose corresponded to 19.8 g of K 2 O per plant per year. The West Indian cherry crop was sensitive to water salinity of 3.8 dS m -1 in the post-grafting phase, resulting in a decline in photosynthetic pigment content and growth. Increasing K doses reduced the percentage of cell membrane damage and promoted increase in the synthesis of chlorophyll a and carotenoids in West Indian cherry plants. There was significant interaction between salinity levels and K doses for the leaf osmotic potential, water saturation deficit, percentage of cell membrane damage and chlorophyll b content in West Indian cherry plants.
