Arbuscular Mycorrhizal Fungi: A Blessing or A Curse for Weed Management in Organic Olive Crops?
(2011)Arbuscular Mycorrhizal (AM) fungi form symbiotic associations with the roots of many plants including important weeds. Cultural practices affect the populations and the infectivity of AM fungi. Density, biomass, root ... -
Are Leaf Glandular Trichomes of Oregano Hospitable Habitats for Bacterial Growth?
(2012)Phyllospheric bacteria were isolated from microsites around essential-oil-containing glands of two oregano (Origanum vulgare subsp. hirtum) lines. These bacteria, 20 isolates in total, were subjected to bioassays to examine ... -
Banana: cultivars, biotechnological approaches and genetic transformation
(2008)Genetic modification of banana has been considered as a path towards increasing the value of this crop according to health and nutrition in developing countries. Banana as a crop is one of the most important and widely ... -
Breeding Objectives and Selection Criteria for Milk Thistle Silybum marianum (L.) Gaertn. Improvement
(2013)Milk thistle [Silybum marianum (L.) Gaertn.] is an important medicinal-industrial plant. The medicinal compounds of milk thistle are derived from its seeds. The plant is commercially cultivated for the production of ... -
Cultivation of cow cockle (Vaccaria hispanica (Mill.) Rauschert): An industrial-medicinal weed
(2012)Cow cockle (Vaccaria hispanica (Mill.) Rauschert) is an important medicinal weed. Its therapeutic properties are due to present of triterpenoid saponins. Large potential exists to use cow cockle as source of pharmaceutical ... -
Cultivation of milk thistle (Silybum marianum L. Gaertn.), a medicinal weed
(2011)Milk thistle (Silybum marianum L. Gaertn.) is the most researched plant for the treatment of liver disease. Its therapeutic properties are due to the presence of silymarin, a mixture of three flavonolignans (silybin, ... -
Determinants of hazard confronting new entry: Does financial structure matter?
(2000)This paper attempts to identify the determinants of hazard confronting 219 new manufacturing firms established in 1982-84 and followed up to 1992 using a Cox regression model. Three sets of variables are combined in the ... -
Dissipation of pure and broccoli-released glucosinolates in soil under high and low moisture content
(2013)Glucosinolates (GSLs) are secondary metabolites found in Brassica species. Upon tissue disruption GSLs are hydrolyzed by myrosinase enzymes to isothiocyanates (ITCs) which are highly toxic to microbes. Therefore the ... -
Distribution of heavy metals of agricultural soils of central Greece using the modified BCR sequential extraction method
(2007)The state of heavy metal (Cd, Cu, Ni, Zn, Pb, and Cr) pollution was studied, in 440 texturally different soil profiles in Thessaly, an intensely cultivated region in Central Greece. The study was carried out in 2004 and ... -
Effect of two UV-absorbing greenhouse-covering films on growth and yield of an eggplant soilless crop
(2006)The use of UV absorbing films as greenhouse cover material is spreading out in protected cultivation. Although their effects on pest and disease management have received much attention, few studies focus on their effects ... -
Effects of aluminum and moisture levels on aluminum bioaccumulation and protein content in the earthworm Octodrilus complanatus
(2013)Laboratory experiments were conducted to determine the effects of soil aluminum levels and moisture content on aluminum (Al) bioaccumulation and protein content in the earthworm (Octodrilus complanatus). The experimental ... -
Emerging technologies in bioremediation: constraints and opportunities
(2012)Intensive industrialisation, inadequate disposal, large-scale manufacturing activities and leaks of organic compounds have resulted in long-term persistent sources of contamination of soil and groundwater. This is a major ... -
Growth, grain yield and nitrogen use efficiency of Mediterranean wheat in soils amended with municipal sewage sludge
(2014)The application of sewage sludge (SS) to agricultural land can improve soil fertility and physical properties, and enhance crop production. This field study was conducted for two consecutive growing seasons to investigate ... -
Heavy metal concentrations in soils and irrigation waters in Thessaly region, Central Greece
(2005)The purpose of this work was to provide information on heavy metals concentrations in soils and in irrigation water in Thessaly, Central Greece, where tobacco (Nicotiana tabacum) is cultivated. Tobacco tends to accumulate ... -
How apple responds to boron excess in acidic and limed soil
(2013)Two year-old apple plants (Malus domestica cv. Red Chief Delicious) were grown in an acidic and limed soil, and fertilized with B (0, 1, 3 and 5 mg kg(-1) soil). Fresh matter weight of plants was positively correlated with ... -
Influence of Ambient Ozone Pollution on Olive Leaf Gas Exchange Irrigated with Saline Water
(2011)Saline water is often available for irrigation and ambient ozone pollution is significant in the Mediterranean region. These two factors may negatively affect cultivated plant productivity. We studied the effects of a ... -
Influence of some soil parameters on heavy metals accumulation by vegetables grown in agricultural soils of different soil orders
(2008)The main purpose of this research was to determine the levels of heavy metals in tomato, potato and lettuce, grown in agricultural soils of different soil orders (Alfisols, Endisols and Vertisols), located at Central Greece. ... -
Location and survival of new entry
(2000)Drawing from two different strands of literature, industrial ecology and spatial analysis, the paper attempts to examine the role that location plays in determining firm survival. A time-varying covariates hazard model is ... -
Major and trace element contents in apples from a cultivated area of central Greece
(2013)Forty-two soil and apple samples from central Greece were collected and analyzed with regards to the content in major (Ca, Fe, K, Mg, Na, P, and S) and trace elements (As, B, Ba, Cd, Co, Cr, Cu, Hg, Mn, Mo, Ni, Pb, Sb, Sc, ... -
