Bemisia tabaci is one of the most devastating pests in tomato greenhouse production. Insecticide resistance management for B. tabaci requires a novel approach that maximizes non-chemical methods for pest control. The aim of this study was to test the effects of rootstocks on B. tabaci populations in hydroponically grown tomato plants. In order to contribute to the better understanding of the me...

in order to locate the qtls involved in the inheritance of agronomical, physiological and metabolitical indicators of drought tolerance in barley, an experiment was carried out using a wheat-barley disomic addition lines. this research was conducted in 2003-2004 at the dry land agricultural research institute, sararood, kermanshah, iran. the results of analysis of variance revealed highly signi...

The seasonal changes of leaf physiological traits and its relationship with abiotic factors (photosynthetic active radiation-PAR, leaf temperature-Tleaf, air temperature-Tair, Tleaf - Tair- ΔT) were studied on sugar beets grown under the semi-arid conditions of central Greece. Sugar beet (Beta vulgaris L.) cv Rizor was established in a Randomised Complete Block design experiment for two years (...

drought, ultraviolet radiation and atmospheric co2 are some three environmental factors that seriously affect future food security. the objective followed in the present research was to study the effect of two levels of carbon dioxide (400 and 900 ppm), ultraviolet radiation (uv a, b and c with intensities of 18, 25 and 40 microw.cm-2 respectively) and water deficit (%100 and %60 of field capac...

Although water and land pollution are very dangerous, air pollution has its own peculiarities due to its transboundary dispersion of pollutants over the entire world. In any well planned urban set up, industrial pollution takes a back seat and vehicular emissions take precedence as the major cause of urban air pollution. In the present study, Air pollution tolerance index was calculated for var...

abstract pistachio ( pistacia vera l.) is an important crop in our country and has a unique position in export goods. in respect to better nut quality this research was conducted during 2005-2006. macro and micronutrients were used as foliar application to surmount soil limitations in nutrient uptake and alternate bearing control with “owhadi” cultivar in rcbd with 3 replications. the treatment...
