Seed oil content is an important trait of nut seeds, and it is affected by the import of carbon from photosynthetic sources. Although green leaves are the main photosynthetic organs, seed sarcotesta photosynthesis also supplies assimilates to seed development. Understanding the relationship between seed photosynthesis and seed development has theoretical and practical significance in the cultiv...

Satureja hortensis L., (summer savory) is an annual, herbaceous aromatic and well-known medicinal plant. S. hortensis essential oil has a high percentage of carvacrol which is responsible mainly for its biological activity. The biomass production, essential oil composition and mineral content of Satureja hortensis are known to be dependent on its growth and development conditions. The aim of th...

In terms of sharp drop of international oil prices in the second half of 2008 after heading skyward in the first half of 2008 following continual growth since 2005, while at the same time certain parity among energy prices was disrupted, the author of this article tried to investigate key factors that influenced oil and gas industry and to answer the question what would be a »fair» price of cru...

The essential oil from the leaves of Juglans regia L. (Juglandaceae) growing wild in Kashmir (India) was obtained by hydro-distillation and analysed during different stages of growth ranging from April to October.

The olive tree is a plant of economic value for the oil of its drupe. It is a cultigen complex composed of genotypes with differences in cold-hardiness. About 90% of the oil is stored in oil bodies (OBs) in the drupe during the oleogenic phase. Phenols and lipids contribute to oil quality, but the unsaturated fatty acid (FA) fraction is emerging as the most important for quality, because of the...

Rates of hydrocarbon biodegradation were estimated by following oxygen uptake during mineral oil oxidation or oxidation of [1-14C]hexadecane to 14CO2, when these substrates were added to natural water samples from Wisconsin lakes. A lag phase preceded hydrocarbon oxidation, the length of which depended on population density or on factors influencing growth rate and on the presence of nonhydroca...
