Calendula officinalis (Marigold) was characterized in respect to its chemical composition, antioxidant potential and antimicrobial activities. Five compounds were identified and quantified by LC/MS and HPLC in leaves and flowers of aqueous-methanolic extracts. Total flavonoids ranged between 44.91 and 76.44 mg QE/g dry weight in leaf and flower extracts, respectively. Rutin, quercetin-3-O-gluco...

Single clover plants were grown in the vegetative state, at 20 +/- 1 degrees , 85 +/- 5% relative humidity, 320 +/- 10 ppm CO(2), 12-hour day, with Hoagland nutrient in Perlite, and 100 w . m(-2) of photosynthetically active radiation (0.4-0.7 mu) from mercury-fluorescent lamps. Each plant was confined within a circle 18 cm in diameter by means of a wire framework. The CO(2) exchange rate of th...

A pot experiment was carried out spring season on 16 ⁄ 3 2019 one fields College Agriculture - University Anbar, by following design complete randomized sectors RC...

wheat, cv. alvand, under late sowing condition and comparison with conventional sowing date was investigated in a field experiment in 2009-2010. the factors were seven levels of priming by sa, including control or untreated seeds, 400, 800, 1200, 1600, 2000 and 2400 µm sa and two sowing dates including conventional sowing date (23 october) and late sowing (22 november). results showed that prim...

Four-week-old French Colombard plants rooted from green cuttings were inoculated with 0, 1,000, 2,000, 4,000, or 8,000 Meloidogyne incognita second-stage juveniles and maintained at 25 C night and 30 C day. Leaf area and dry weight and the rates of photosynthesis, stomatal conductance, and internal leaf CO concentration were measured at intervals up to 59 days after inoculation. Nematode stress...

This study was conducted to assay the effects of methanol foliar application (0, 10, 20 and 30% v/v) and bed cover (control, white and black covers) on yield and some physiological traits of marigold as a factorial based on RCBD. The results revealed the significant interaction effects of bed cover and methanol foliar application on chlorophyll a content and plant height. The highest plant heig...
