Olive cultivar diversity is rich in Algeria but most remain unexplored terms of quality traits. This work aimed to evaluate the physicochemical and organoleptic twenty olive oil samples belonging four Algerian cultivars ( Chemlal , Sigoise Ronde de Miliana Rougette Mitidja ) collected throughout national territory. Physical-chemical sensory results showed that 60% oils belong extra virgin categ...

olive oil is one of the oldest known vegetable oils, ranking sixth in world production. since it is extractedfrom fresh fruit and used without aging, the conditions of oil production are very important. during theextraction of virgin olive oil, the milling and malaxation steps are vital for increasing oil yield and quality.in this study, the effect of milling (single or double), temperature of ...

The effect of salinity was assessed on the activity of some major antioxidant enzymes i.e., superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), in the seedlings’ roots or shoots of three winter canola (Brassica napus L.) cultivars, Colvert (tolerant), Symbol (semi tolerant) and Agat (susceptible). Seedlings were treated with 0 (control), 50, 100 and 150 mM NaCl for 24 h in hydropoic c...

Background: Root-knot nematodes (Meloidogyne spp.) are the most devastating pests of vegetables, especially in tropic and subtropic regions. Meloidogyne incognita is among major pathogens found tomato crop causes a significant yield loss. This study evaluates resistance susceptible cultivar against root-knot incognita). Methods: A greenhouse was conducted to evaluate or susceptibility nine cult...

The analysis of the secoiridoid type phenolic compounds present in virgin olive oil has become a challenging area research since first evidence their presence polar fraction oil. Separation techniques, mainly liquid chromatographic ones, prevailed over years application toward elucidation structure, content determination and collection on cultivar, origin, processing storage conditions dependen...

Ozone (O3) is one of the major atmospheric pollutants in the Mediterranean area and negatively interacts with several biochemical and physiological processes of the plants. Olive is one of the most widely cultivated trees in the Mediterranean climates and previous studies have shown that O3 can potentially interfere with olive trees productivity. In order to test the physiological and biochemic...

The galanthamine, lycorine, and lycoramine content of Lycoris chinensis was researched during development from young to old plants, i.e. in seeds, ten-day-old seedlings, three-month-old seedlings, one-year-old seedlings, and perennial seedlings. Notably the alkaloid level reduced to its lowest content 10 days after seed germinating. Then the accumulation of galanthamine tended to increase with ...
