for evaluation of drought tolerance of sugar beet genotypes by assessment of the drought tolerance indices under mild and severe stresses, furrow irrigated field experiments were carried out at zarghan research station in 2002 and 2004, and at motahari research station (located inkaraj) in 2002, 2003, and 2004. the experimental design was split plot, with a randomized complete block arrangement...

soil and water salinity are amongst the severe and progressive problems worldwide which affects most cropland areas of iran. using endophytic microorganisms (which are amongst the most important soil microorganisms) to alleviate the detrimental effect of environmental stresses such as salinity is recently globally considered. in order to test the effects of azospirillum strains and fungus pirif...

a field experiment was carried out during 2001 in the experimental fields of sugar beet seed institute in karaj. the objective of this study was to determine the response of some quantitative and qualitative traits of three sugar beet lines subjected to continuous water stress and normal conditions. three sugar beet lines 7219-p.69, bp-karaj and 7112 as tolerant, semi tolerant and sensitive to ...

the production of oxygen radicals in plants under salinity stress conditions in an the important factor for a diminishing of a photosynthesis and a cause fir a decrease in later vegetative growth. in order to study the effects of antioxidants and salinity stress on photosynthetic characteristics and growth in olive, an experiment was conducted in the research greenhouse of tabriz university in ...

Growth response of sugar beet plants to drought stress applied at different growth stages has been investigated. Cessation of watering imposed moderate water stress and resulted in the reduction of the relative water content of young and old leaves maximally by 6%. However, water content in taproot was more drastically decreased than in the shoot. Water withholding reduced dry ma�er accumulatio...

Borage is an important medicinal plant which must be cultivated commercially in order to meet the ever-increasing demand for pharmaceutical industry. This study was done under hydroponics condition. Seeds of Borage were obtained from Neka Research Center (North of Iran). After applying Benomyl fungicide, the seeds were rinsed with distilled water and planted in vermiculite. After germination an...

ABSTRACT- A detailed understanding of crop rooting systems will facilitate water use reduction, optimized nutrient uptake and irrigation scheduling more efficiently. A field experiment was conducted during 2005-2006 to investigate sugar beet rooting depth growth, irrigated with three irrigation methods (subsurface drip, surface drip and furrow) and two water qualities (recycled wastewater: EC= ...
