Rosmarinus officinalis is a well-studied species; however, R. essential oil (EO) from West highlands of Algeria was not investigated chemically and biologically. In this context, chemical composition EOs obtained leaves stem were determined by GC/MS analysis their antifungal activity against Fusarium oxysporum f. sp. albedinis (Foa) evaluated. The indicated that monoterpenes the dominant class ...

The desired future condi t ion the overstory is a product ive pinelhardwood mixture, wi th white pine, which is resistant to southern pine beetle (Dendroctonus frontalis...

A fundamental goal in ecology is to link variation in species function to performance, but functional trait-performance investigations have had mixed success. This indicates that less commonly measured functional traits may more clearly elucidate trait-performance relationships. Despite the potential importance of leaf vein traits, which are expected to be related to resource delivery rates and...

To understand the physiological mechanism by which soybean (cultivar: Glycine max L. Merr. cv.JH13) regulates its growth in response to drought under elevated CO 2 concentration, a pot experiment with two levels of CO 2 (350 vs. 700 μmol·mol) and two levels of water (well irrigated vs. drought) was conducted. Plant relative growth rate (RGR), water potential (WP), photosynthetic pigment (chloro...

The objective of this study was to develop a growth model for grafted hot pepper seedlings as affected by air temperature and light intensity. After union formation, the were cultivated in various environmental factors terms four levels, mean daily (17, 22, 27, 32 °C) 3 levels intensity (150, 350, 550 ?mol·m?2·s?1). traits measured 0, 7, 14, 21, 28 days after formation (DAGU). plant height impr...

Oilseed crops grown in different types of soil experience nutrient deficiency, especially sulphur, zinc and boron, which affect crop productivity. To tackle it, management practices must be streamlined to avoid improper fertilizations deterioration health. With this background, experimental trials were conducted study the effect boron application on growth, yield components hybrid sunflower at ...

introduction growth analysis has been widely used in breeding programs to identify the important plant developmental phases and components related to higher yield under a particular set of environmental conditions. castor bean (ricinus communis l.) is an important commercial crop. castor oil based by products is used in manufacturing of several commercially important commodities like surfactant...

The combined effects of water activity ([a(w)] 0.99 or 0.95), pH (4.5 or 3.5) and antimicrobial agent (potassium sorbate, sodium benzoate, sodium bisulfite, carvacrol, citral, eugenol, thymol, or vanillin) concentration (0, 100, 200 up to 1800 ppm) on the growth of Aspergillus flavus were evaluated in potato dextrose agar (PDA). Mold spore germination time and radial growth rates (RGR) were sig...
