The Impact of Deficit Irrigation on the Agronomic Performance and Chemical Comp...
Polyzos, Nikolaos; Paschoalinotto, Beatriz H.; Pires, Tânia C.S.P.; Añibarro-Ortega, Mikel; Calhelha, Ricardo C.; Ferreira, Isabel C.F.R.In the current study, the effects of drought stress on the growth and phytochemical profile of Scolymus hispanicus L. (a.k.a. golden thistle) were evaluated. Plants were treated with three irrigation regimes, e.g., plants that received only rainwater (Control; C), deficit irrigation (I1; 50% of field capacity (FC)), and full irrigation (Ι2; 100% of FC). The fresh weight of the rosette of leaves was not negative...
Biochemical Composition of Pumpkin Seeds and Seed By-Products
Polyzos, Nikolaos; Fernandes, Ângela; Calhelha, Ricardo C.; Petrović, Jovana; Soković, Marina; Ferreira, Isabel C.F.R.; Barros, LillianThe goal of the current work was to assess the nutritional profile and phytochemical properties of cucurbit (Cucurbita maxima L.) seeds, seed oils and oil extraction by-products (e.g., seed-cakes). Our results suggest a high nutritional value for both cucurbit seeds and cucurbit cake, while γ-tocopherol was the richest compound, with traces of α, β and δ-tocopherol compounds also detected. Regarding the free su...
Domestication of wild edible species: the response of Scolymus hispanicus plant...
Paschoalinotto, B. H.; Polyzos, Nikolaos; Compocholi, Maria; Rouphael, Youssef; Alexopoulos, Alexios; Dias, Maria Inês; Barros, LillianScolymus hispanicus L. is a wild edible species with wide distribution in the Mediterranean area. Recent research has focused on the domestication of wild edible greens, which is essential for the preservation of agroecosystems and the increase in biodiversity, especially under the adversely changing climate conditions. In the present work, the aim was to evaluate the response of S. hispanicus plants to differe...
Combined effect of biostimulants and mineral fertilizers on crop performance an...
Fernandes, Ângela; Polyzos, Nikolaos; Mandim, Filipa; Pereira, Carla; Petrović, Jovana; Soković, Marina; Petropoulos, Spyridon Α.The aim of the present study was to evaluate the possible effects of two different biostimulant formulations at different application regimes and combined or not with mineral fertilizers (e.g., W1–W8, including the control treatment (no formulations added)) on the yield parameters and fruit quality of watermelon plants. The highest yield was recorded for the W5 treatment due to the formation of more fruit. The ...
Fertilization of pot-grown Cichorium spinosum L.: how it can affect plant growt...
Polyzos, Nikolaos; Paschoalinotto, B. H.; Compocholi, Maria; Pinela, José; Heleno, Sandrina A.; Calhelha, Ricardo C.; Dias, Maria Inês; Barros, LillianCichorium spinosum L. is a perennial wild edible plant that is usually found near the coasts of the Mediterranean basin. In the present study, we evaluated the effect of the fertilization regime on the growth and chemical profile of pot-grown C. spinosum plants, as well as the effect of extraction protocol (aqueous and hydroethanolic extracts on bioactive properties). For this purpose, plants were fertilized vi...

Paschoalinotto, B.H.; Prieto Lage, Miguel A.; Compocholi, Maria; Polyzos, Nikolaos; Petropoulos, Spyridon Α.; Ferreira, Isabel C.F.R.; Dias, Maria InêsIntrodução - Scolymus hispanicus L. (cardo dourado) é uma planta silvestre comestível da região do Mediterrâneo, tradicionalmente consumida pelos seus efeitos benéficos para a saúde, o que tem vindo a despertar grande interesse para a produção controlada1. Objetivos e metodologia - Avaliação do efeito da adubação, usando soluções nutritivas com diferentes rácios de azoto (N), fósforo (P) e potássio (K), no perf...
Combinação de diferentes regimes de fertilização e irrigação para a produção de...
Paschoalinotto, B.H.; Prieto Lage, Miguel A.; Polyzos, Nikolaos; Compocholi, Maria; Petropoulos, Spyridon Α.; Barros, Lillian; Dias, Maria InêsScolymus hispanicus L. (cardo dourado) é uma planta silvestre comestível que foi popularmente inserida no passado na Dieta Mediterrânica e que caiu em desuso em prol de outras espécies mais apreciadas pelo consumidor [1]. Considerando a atual preocupação por uma alimentação mais funcional e, consequentemente, mais saudável dos consumidores, a par da perda de biodiversidade pela colheita irracional de espécies s...
Nutritional profile and mineral content of Sonchus asper: a wild edible plant f...
Paschoalinotto, B.H.; Prieto Lage, Miguel A.; Compocholi, Maria; Polyzos, Nikolaos; Petropoulos, Spyridon Α.; Ferreira, Isabel C.F.R.; Dias, Maria InêsAgrobiodiversity as part of overall biodiversity can be defined as the variety of living forms within agricultural ecosystems and is strongly linked with diversity in food and agricultural production and, thus, with nutrition and human health. In addition to the diversity of common crop species, Mediterranean agrobiodiversity resources also include Wild Edible Plants (WEPs)1. Sonchus asper is considered a wild ...
The bioactivities and chemical profile of turnip-rooted parsley germplasm
Petropoulos, Spyridon Α.; Fernandes, Ângela; Finimundy, Tiane C.; Polyzos, Nikolaos; Pinela, José; Ivanov, Marija; Soković, MarinaIn the present study, the chemical profile and bioactive properties of the roots of turnip-rooted parsley (Petroselinum crispum spp. tuberosum) germplasm were evaluated. For this purpose, plants from seventeen parsley cultivars were grown in 6 L pots, and the obtained roots were analyzed in terms of nutritional value, chemical composition (tocopherols, sugars and organic and fatty acids) and bioactive content (...
