The effect of foliar application of zinc sulfate and seaweed on qualitative and quantitative characteristics of local Kermanshah cantaloupe (Cucumis melo L., Cantalupensis Group) cv. Kalak was investigated. After sowing seeds in the field, the plants were sprayed in three stages including the 4-6 leaf stage, flowering and after the fruit set. The experiment had a factorial design based on the r...
Background: Purple laver ((Porphyra dentate) is a popular edible seaweed in Asia. This study examined protective effects of extract from purple laver extract (PLE) in diabetic mice. Methods: Content of carotenoids and anthocyanins in PLE was analyzed. PLE at 0.5 and 1% was supplied for 7 weeks. Results: PLE was rich in anthocyanins. PLE intake at 0.5 and 1% lowered plasma glucose level (P<0.05)...
The effect of seaweed liquid fertilizer (SLF) of Sargassum myriocystum on germination, growth and biochemical constituents of Vigna mungo was studied. Different concentrations (5%, 10%, 25%, 50% and 75%) of SLF were prepared using distilled water. A total of 100 seeds were soaked for each SLF concentration for a 24-h period and were later placed in various Petri plates and watered regularly. Wa...
BACKGROUND: Biofertilizers, like amino acids, are used to reduce drought stress damage to plants and improve physiological factors, thereby increasing plant yield in arid and semi-arid regions. Seaweed extract has a beneficial effect on plant growth due to its growth hormones and elements such as iron, copper, zinc, cobalt, molybdenum, manganese and nickel, vitamins and amino a...
Two of the most important challenges facing humanity in the 21st century comprise food production and disease control. Eco-friendly control tools against mosquito vectors and agricultural pests are urgently needed. Insecticidal products of marine origin have a huge potential to control these pests. In this research, we reported a single-step method to synthesize silver nanoparticles (AgNP) usin...
The production of methane biofuel from seaweeds is limited by the hydrolysis of polysaccharides. The rumen microbiota of seaweed-eating North Ronaldsay sheep was studied for polysaccharidic bacterial isolates degrading brown-seaweed polysaccharides. Only nine isolates out of 65 utilized >90% of the polysaccharide they were isolated on. The nine isolates (eight Prevotella spp. and one Clostridiu...
A celebrated theorem of Suslin asserts that a unimodular row x1 1 , . . . , x mn n is completable if m1 · · ·mn is divisible by (n − 1)!. Examples due to Suslin and to Mohan Kumar and Nori show that this result is the best possible in all characteristics. We give a new version of the proof of Mohan Kumar and Nori which avoids the need to use Grothendieck’s Riemann– Roch theorem or other deep re...
Extensive use of chemicals in crop production has attracted global public concerns in terms of their effects on human health. The issue has led to movement toward reducing chemicals and replacing with environmentally-friendly compounds during production processes of agricultural crops. An experiment was carried out to evaluate the effects of fertilizers with biologic origin, including seaweed e...
Seaweeds are rich sources of bioactive natural products, which have been considered as potential biotic agents. Ulva flexuosa Wulfen is a species of seaweed which is endemic to the Persian Gulf. In this study, the effect of different concentrations of U. flexuosa extract on the antioxidant activity of Washington Navel orange (Citrus sinensis L. cv. Washington Navel)...
