Effects of foliar and soil boron fertilization on yield, leaf physiological tra...
Silva, A.P.; Aires, Alfredo; Barreales, David; Rodrigues, M.A.; Ribeiro, A.C.; Gonçalves, Berta M.; Morais, Maria C.Boron (B) fertilizers are recognized as essential for ensuring yield and fruit quality. However, the importance of soil and foliar B fertilization in almond orchards under rainfed conditions is presently unclear. To address this literature gap, in the present study, the impact of soil and foliar application of B on leaf gas exchange, leaf photosynthetic pigments, yield, and fruit quality in almonds was investig...
Combined soil and foliar nitrogen fertilization effects on rainfed almond tree ...
Morais, Maria Cristina; Aires, Alfredo; Barreales, David; Rodrigues, M.A.; Ribeiro, A.C.; Gonçalves, Berta C.C.; Silva, A.P.Cultivation of almond in the Mediterranean region is traditionally done under rainfed conditions and poorly established cropping practices resulting in low yields. Despite the importance of nitrogen (N) fertilization to increase yield in cultivated species, this practice is usually neglected in rainfed managed almond orchards. Selection of the most appropriate rate and method of nitrogen (N) application are utm...
Manual prático da amendoeira
Ribeiro, A.C.; Silva, A.P.A amendoeira é uma das principais culturas de frutos secos cultivadas em Portugal. As baixas produtividades da cultura estão associadas a uma instalação deficiente de muitos amendoais tradicionais de sequeiro, em áreas pouco aptas para a cultura e com técnicas culturais pouco adequadas. As condições climáticas durante o período de floração, em particular a ocorrência de geadas, a que acresce o acentuado défice ...
Physiological and biochemical performance of almond trees under deficit irrigation
Prgomet, Iva; Pascual-Seva, Núria; Morais, Maria Cristina; Aires, Alfredo; Barreales, David; Ribeiro, A.C.; Silva, A.P.; Barros, Ana I.R.N.A.The almond tree is generally recognized as drought-tolerant, though it depends on water resources to achieve high yields. During the summer months of two consecutive years, several physiological and biochemical parameters were observed, to understand the almond tree’s seasonal sensitivity and behavior under different irrigation strategies based on crop evapotranspiration (ETc): T100 optimal water requirement re...
What is the role of the new index relative fat mass (RFM) in the assessment of ...
Machado, M.V.; Policarpo, S.; Coutinho, J.; Carvalhana, S.; Leitão, J.; Carvalho, A.; Silva, A.P.; Velasco, F.; Medeiros, I.; Alves, A.C.; Bourbon, M.Introduction: Nonalcoholic fatty liver disease (NAFLD) is the liver manifestation of adiposopathy. Recently, a new score was developed to estimate body fat percentage (relative fat mass, RFM). We aimed to evaluate the value of RFM in predicting the presence and severity of NAFLD, compared with other anthropometric measurements. Methods: RFM, body mass index (BMI), and other anthropometric measurements were eval...

Variation of almond yield, biometry, α-tocopherol levels, and antioxidant prope...
Aires, Alfredo; Morais, Maria Cristina; Barreales, David; Rodrigues, M.A.; Ribeiro, A.C.; Gonçalves, Berta C.C.; Silva, A.P.A two years’ experiment (2015–2016) was set in a factorial design in which the effect of two application forms of nitrogen (N) (soil and soil + foliar spray) in different doses (0, 25, 50, and 100 kg N ha-1) on almond (Prunus dulcis Mill. cv. “Masbovera”) was evaluated. Kernel yield, biometric properties, phytochemicals, and antioxidant activities were assessed. The results showed that almond kernel yield incre...
Rega deficitária em amendoeira: economicamente vantajosa sem comprometer a prod...
Morais, Maria Cristina; Aires, Alfredo; Morais, Silvina; Barreales, David; Ribeiro, A.C.; Victor, João; Gonçalves, Berta C.C.; Silva, A.P.A amendoeira (Prunus dulcis (Mill.) D.A.Webb) é uma das espécies de frutos secos mais característica da paisagem da Terra Quente Transmontana. Embora se trate de uma cultura bem adaptada às condições edafoclimáticas desta região, a produtividade dos amendoais é geralmente baixa devido, em parte, ao uso de técnicas de produção pouco adequadas. De facto, o cultivo desta espécie na região transmontana continua a s...
Hepatic steatosis in an adult population: stronger correlation with the presenc...
Leitao, J.A.M.C.P.; Cochicho, J.; Carvalhana, S.; Velasco, F.; Silva, A.P.; Medeiros, I.S.; Alves, A.C.; Bourbon, M.; Oliveiros, B.; Rodrigues, V.Background and Aims: Hepatic steatosis is very frequent in thegeneral population, mostly associated with obesity and insulinresistance. Typical dietary patterns have been difficult to identifywith controversial information. We aimed to estimate in a represen-tative sample of the Portuguese adult population, what was thecontribution of the dietary pattern in what concerns macronutrientsand food groups for the pr...
Prevalence of alcoholic steatosis in the general adult Portuguese population
Leitao, J.A.M.C.P.; Carvalhana, S.; Cochicho, J.; Silva, A.P.; Velasco, F.; Medeiros, I.S.; Alves, A.C.; Bourbon, M.; Oliveiros, B.; Rodrigues, V.Background and Aims: Fatty liver is very frequent in the general population. Although many studies evaluated the prevalence of nonalcoholic fatty liver disease there is scarce information regarding alcoholic fatty liver. We aimed to estimate the prevalence of alcoholic hepatic steatosis, and to what extent it depended on obesity and its interaction.
