mprovement of N2 fixation might be an effective strategy in peanut breeding for high yield under drought stress conditions. However, under water limited conditions peanut varieties having high water-use efficiency (WUE) are favorable. A pot experiment was conducted under greenhouse conditions at Khon Kaen University, Thailand during December 2002 to May 2003, and repeated during June 2003 t...

MicroRNAs (miRNAs) are small non-coding RNAs that play critical roles in plant development and abiotic stress responses. The miRNA transcriptome (miRNAome) under water deficit stress has been investigated in many plant species, but is poorly characterised in durum wheat (Triticum turgidum L. ssp. durum). Water stress during early reproductive stages can result in significant yield loss in durum...

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 ...

In order to study the effects of different irrigation regimes and plant density on yieldcomponent and protein concentration and crop water stress index (CWSI), under research fieldconditions a split plot arrangement was conducted in completely randomized block designduring two years. The first factor of variables was the effects of 4 irrigation levels 120% (I1),100% (I2), 80% (I3) and 60% (I4) ...

root and shoot osmotic and elastic properties of two species of haloxylon aphyllum and h.persicum in response to water stress were studied. the main goal of the study was to determine if the tissuesof two species utilize osmotic adjustment and/or enhance their elastic property during prolonged water stresscondition. the results showed that although tissue elasticity of both species of haloxylon...

In this study, seven walnut populations (Rabor, Hanza, Sardoueih, Dalfard, Bidkhan, Dehbakri, and Baft) were selected from Kerman province and compared for drought stress tolerance. Water potential between 0 and -1.5 MPa was obtained by polyethylene glycol 6000 solutions. Germination percentage, leaf relative water content (LRWC), and growth parameter of seedlings diminished with increasing dro...
