introduction obtaining varieties with acceptable yield and tolerant to different arid and semi-arid climate condition of iran is an important goal in canola breeding programs. selection of genotypes base on one or more traits without regarding to correlation between them, could biases the expected results. therefore, identifying of genetic correlation among traits especially in environmental st...

The effects of lead on the proline content and dry weight of leaves and roots were investigated in two canola cultivars (Brassica napus L.) grown in the Hoagland solution. The growth of treated plants was inhibited under lead stress. Lead induced differential accumulation of proline in canola grown in solution with the addition of 0, 100 and 200 mgL-1 of Pb. Hyola308 cultivar showed low biomass...

in order to evaluate the effects of methanol on germination percentage, germination speed index, plumule and radicle length, plumule and radicle dry weigh, vigor index and consumed endosperm of bean in condition of water deficit, a factorial experiment done based on completely randomized design with three replications. the first factor was different levels of methanol included 0 (control), 5, 1...

BACKGROUND Occupational stress is a psychosocial dimension of occupational health concept on social determinants of health, especially, job & environmental condition. Recently, staff network of different government universities of Thailand have called higher education commission, and Ministry of Education, Thailand to resolve the issue of government education policy (e.g. wage inequity, poor we...

salt stress is a factor limiting crop growth and productivity around the world. developing salt tolerant cultivars using desired plant features has been considered as a way to cope with the problem. in this study, a factorial experiment was used in order to determine the effects of salt stress on stomatal length at abaxial and adaxial leaf surfaces, relative water content (rwc) and transpiratio...

water deficit is one of the most common constraints to crop productivity in the world and iran. in order to study effect of drought stress on morphologic traits, yield and yield components of 34 hybrids of corn, an experiment was carried out based of complete randomized block design with three replication under f.c. irrigation and drought stress in khorasan razavi agricultural research and natu...

in the current study, a set of 96 recombinant inbred lines (ril) at f8, derived from a cross between two varieties, anbarbu (sensitive to drought stress) and sepidroud (tolerant to drought stress) were used. the experiment was performed at gonbad kavous located in the golestan province of iran in 2010–2011 using two augmented designs at normal and stress conditions, separately. the ril populati...

In this letter, the characteristics of positive bias temperature instability (PBTI) and hot carrier stress (HCS) for the lowtemperature poly-Si thin-film transistors (LTPS-TFTs) with HfO2 gate dielectric are well investigated for the first time. Under room temperature stress condition, the PBTI shows a more serious degradation than does HCS, indicating that the gate bias stress would dominate t...
