The pine nuts, as the most expensive ones, are a source of healthy oil. Accordingly, the hypothesis was genetic differences of pine species (Pinus spp.) affect their nut oil content and fatty acid phytovariability. A completely randomized design experiment with three replicates was done in Isfahan Flower Garden, Iran, using four pine species of chir pine (Pinus longifolia<...

Stone pine (Pinus pinea) grows in natural stands within the Mediterranean basin and its nut is highly appreciated for nutritional profile. Nevertheless, a decline this species due to biotic abiotic damages currently being clearly observed. This situation has led development as crop, try save production obtain regular harvests over years. Under agronomic scenario, aim of work was compare behavio...

the big eye kilka, clupeonella grimmi, is a marine fish living in depth of 20 to 200 meter of the caspian sea. its eye and retina were processed for histological and sem studies. paraffin embedded retina was cut radially and tangentially in 5 ?m thickness and stained with hematoxylin and eosin method. the unstained sections were manipulated for sem image observations. tangential retinal section...

The time interval between stand-replacing fires can influence patterns of initial postfire succession if the abundance of postfire propagules varies with prefire stand age. We examined the effect of fire interval on initial postfire lodgepole pine (Pinus contorta var. latifolia Engelm.) density in Yellowstone National Park (YNP) following the 1988 fires. We asked whether postfire propagule abun...

hSTRACT.-htomatk cameras were used to record adult red-cockaded woodpecker (pi-coides borealis) nest visits with food for nestlings. Diet of nestlings on or near an old-growth longleaf pine (Pinus palustris) remnant in southern Georgia was compared to that in longleaf pine stands established on old farm fields in western South Carolina. Diets of nestlings were expressed as percent nest visits a...

The traditional method of gas chromatography-mass spectrometry for monosaccharide component analysis with pretreatment of acetylation is described with slight modifications and verified in detail in this paper. It was then successfully applied to the quantitative analysis of component monosaccharides in polysaccharides extracted from the pine cones. The results demonstrated that the three pine...

Maritime pine (Pinus pinaster Ait.) is native to the western Mediterranean basin and has an economic importance in southwestern Europe. This based on use of its wood construction, furniture, paper industries. Bark other parts plant, such as resin, needles, cones, are by-products with potential industrial application. These tree stand out because presence secondary metabolites, main ones being p...

In Quebec, jack pine (Pinus banksiana Lamb.) is an important commercial species, used principally for timber wood and pulp. The natural ecology of jack pine is related to fire, which allow opening of the cones and dispersal of seeds (Burns and Honkala 1990). The exploitation of jack pine stands disturbs this cycle and the regeneration remains low after harvesting and plantation must be done to ...
