    Asparagus officinalis is a spring vegetable contains flavonoids, amino acid derivatives, glycolic acid, tyrosine, vitamins, saponins and essential oils and it has health benefits such as prevention of cancer, mutation, inflammation, and liver damage. The aim of this study is to investigate drying kinetics of Asparagus officinalis. According to R, ¤ç2, RMSE and Error values, the model parameters at different temperatures (70┬░C, 80┬░C, 90┬░C), spear thickness (1 mm, 2 mm and 3mm), and microwave power (100 W, 200 W, and 300W) were compared. Midilli and Kucuk equation was found as the best equation to describe drying of Asparagus officinalis. R values of Midilli and Kucuk Equation changed between 0.8886 and 0.9989 for hot air drying and between 0.9568 and 0.9999 for a microwave drying

    Effect of NaCl on Asparagus Quality, Production and Mineral Leaching

    Previous research has shown that the incidence of Fusarium oxysporum and F. redolens on asparagus roots was reduced by field applications of NaCl. F. oxysporum and F. redolens are important diseases in asparagus crops causing physiological rust (brown discoloration on the harvested spears), reduced yields, smaller spears, plant losses and may be implicated in asparagus decline. Since 2001 research has been carried out in Lelystad with asparagus plants grown in large wooden containers filled with a typical asparagus replant soil to study the effect of applications of Asparagus Salt (NaCl with addition of Mg) on asparagus quality, production and mineral leaching. In 2003 and 2004 the trial was harvested for a period of 35 days each year. In 2004 spears were graded into standard sizes to identify differences between treatments and to start with an economic evaluation. In both years Asparagus Salt had a positive effect on total yield, marketable yield and number of spears. Field applications of NaCl stimulated earliness in production. The higher loss of Mg due to leaching is compensated by adding Mg to the salt. In this experiment leaching of Mn was also studied in combination with adding Mn to Asparagus Salt

    The potential of biological soil disinfestation to manage Fusarium foot and root rot in Asparagus

    In a field experiment on an abandoned asparagus field we studied the effect of Biological Soil Disinfestation (BSD) on survival of buried inoculum samples of three test pathogens (Fusarium redolens f.sp. asparagi (FRA), Rhizoctonia tuliparum (RT) and Verticillium dahliae (VD)) and on the Fusarium infestation level. The BSD treatments involved incorporation of grass into moist soil and covering the soil with airtight plastic. The amount of grass incorporated was varied (42, 62 or 102 tons of grass/ha) as well as the depth of incorporation (40 or 80 cm). It was found that BSD greatly reduced all three pathogens in buried soil samples and that incorporation of 62 or 102 tons of grass per ha to 80 cm soil depth resulted in a significant decrease in soil infestation in the upper 40 cm; in the deeper layer the decrease was lower. Asparagus plants grown from seed in the field for one year showed a strong decrease in Fusarium root rot severity with all BSD treatments. The results clearly show the potential of BSD to decrease soil infestation levels of Fusarium pathogens and to contribute to an enhanced life span of replanted asparagus crop

    Asparagus (Asparagus officinalis) is a member of the lily family. It has been grown for more than 2,000 years and is quite popular in the home garden today. Asparagus is an excellent source of vitamin A and contains significant levels of calcium, phosphorus, riboflavin, thiamine and Vitamin C

    Medicinal Properties of Selected Asparagus Species: A Review

    Get PDF
    Asparagus species are naturally distributed along Asia, Africa, and Europe and are known to have numerous biological properties. This review article was aimed to provide an organized summary of current studies on the traditional uses, phytochemistry, and pharmacological and toxicological studies of Asparagus laricinus Burch., Asparagus africanus Lam., Asparagus officinalis L., Asparagus racemosus Willd., and Asparagus densiflorus (Kunth) Jessop to attain and establish new insights for further researches. Information used in this review was obtained from electronic database including PubMed central, Google scholars, Science direct, Scopus, and Sabinet. Based on the present findings, the existing literature still presents some breaches about the mechanism of action of various constituents of these plants, and their relation to other plant compounds in poly-herbal formulations, as well as their long-term use and safety. More in-depth studies are still needed for active compounds and biological activities of Asparagus laricinus, Asparagus africanus, and Asparagus densiflorus. Therefore, innumerable opportunities and possibilities for investigation are still available in novel areas of these plants for future research stud┬Čies. It can be concluded that all selected Asparagus species have tremendous potential to improve human health and the pharmacological activities of these plants can be attributed to bioactive phytochemicals they possess

    Antioxidant and antibacterial activities of ethanolic extracts of Asparagus officinalis cv. Mary Washington: Comparison of in vivo and in vitro grown plant bioactivities

    Get PDF
    The antioxidant and antibacterial activities of ethanolic extracts of in vivo grown Asparagus officinalis cv. Mary Washington were investigated using superoxide dismutase, erythrocyte haemolysis and 2,2- diphenyl-1-picrylhydrazil free radical scavenging methods. The measured antioxidant and antimicrobial potential were then compared to the activities offered by the ethanolic extracts of in vitro grown A. officinalis as well as ethanolic extract of undifferentiated callus cells of A. officinalis produced on Murashige and Skoog medium containing 1.5 mg/l 6-benzylaminopurine combined with 0.5 mg/l naphthalene acetic acid. The highest antioxidant capacity was obtained from the in vivo grown plant extract followed by in vitro grown plant extract in all three examined assays. Although, no antibacterial activity was detected from both in vivo and in vitro grown plant extracts in the disc diffusion antimicrobial assay, ethanolic extract of A. officinalis offered antibacterial activity against Bacillus cereus.Key words: Antibacterial activity, antioxidant activity, Asparagus officinalis
