BACKGROUND Camelina sativa is an emerging dedicated oilseed crop designed for biofuel and biodiesel applications as well as a source for edible and general-purpose oils. Such valuable oilseed crop is subjected to plant breeding programs and is suggested for large-scale production of better seed and oil quality. To accomplish this objective and to further enhance its oil content, a better unders...

the genus hypericum is one of the most important medicinal plants that contain 17 species in iran, three of them are endemics. this paper reports the essential oil composition of eight hypericum species from iran. the essential oil analysis of a number of the studied plants has already been reported but their report from iran may be valuable for scientists.  samples collected from different pla...

This experiment was lay out in order to evaluate the effects of different biofertilizers on seed yield, protein and oil of rapeseed in Iran. The experiment was a factorial design with three replications. Treatments were four nitrogen biofrtilizers (control (N1), Nitroksin (N2), Azotobacter (N3) and Supernitroplat (N4)) and three phosphate biofrtilizer...

The commonly used seed spice Cumin (Cuminum cyminum Linn.) contains 3-4% volatile oil and about 15% fixed oil. Conventional grinding of cumin is associated with problems of temperature rise, caking, clogging of sieves and deterioration of quality due to loss of volatiles. Shortcomings of the conventional size reduction were obviated by flaking and the effect of flaking on the yield and quality ...

Background Biotechnology enables the production of high-valued industrial feedstocks from plant seed oil. The plant-derived wax esters with long-chain monounsaturated acyl moieties, like oleyl oleate, have favorite properties for lubrication. For biosynthesis of wax esters using acyl-CoA substrates, expressions of a fatty acyl reductase (FAR) and a wax synthase (WS) in seeds are sufficient. R...

Oil content, fatty acid composition and the distribution of vitamin-E-active compounds of selected Turkish seeds that are typically by-products of the food processing industries (linseed, apricot, pear, fennel, peanut, apple, cotton, quince and chufa), were determined. The oil content of the samples ranged from 16.9 to 53.4 g/100 g. The dominating fatty acids were oleic acid (apricot seed oil, ...

In recent years, the demand for plant-derived oils as renewable alternatives to fossil oil has increased due to the rising cost of petroleum and the increased concern about the environment. However, the supply of vegetable oils today relies upon only a few crops with low potential for further increases in oil yields. Redirection of carbon flux from starch to oil in the cereal seed can provide f...

While previous research has been contradictory, potential grain yield responses and seed protein increases have led to con­ tinuing interest in N fertilizer application to soybean (Glycine max (L.) Merr.]. Field experiments were conducted at seven lo­ cations from 1990 to 1991 in Alabama to determine soybean response to N fertilization at various growth stages. Treatments included a factorial a...
