Drought is the major abiotic stress that decreases plant water status, inhibits photosynthesis, induces oxidative stress, restricts growth and finally lead to the reduction of wheat yield. It has been proven that drought priming during vegetative growth stage could enhance tolerance to drought stress at grain filling in wheat. However, whether drought priming imposed at grain filling in parenta...

The low seed germination response and seedling growth of crops to salinity is common problem in Pakistan. To overcome this problem,seed priming used as an economic effective approach. Present study was conducted evaluate the effects halopriming ofseeds on germination, yield tomato under saline conditions. seeds variety ‘Raja’ were primed with 0, 50mM 100mM NH4NO3, KNO3, (NH4)2SO4 solutions for ...

Seed germination is the stage in which plants are most sensitive to abiotic stress, including salt stress (SS). SS affects plant growth and performance through ion toxicity, decreasing seed percentage increasing time. Several priming treatments were used enhance under SS. The objectives of this study (1) identify shorten emergence period, (2) evaluate against SS, (3) induce synchronized germina...

Three studies investigated how subliminally primed thoughts of an agent prior to action can aVect ascriptions of authorship for that action. Participants competed against a computer program to remove words from a computer screen. Participants reported greater feelings of authorship when primed with Wrst person singular pronouns, and lower feelings of authorship when primed with “computer.” We a...

Memory T cells respond in several functionally different ways from naive T cells and thus function as efficient effector cells. In this study we showed that primed T cells were more resistant to Fas-mediated activation-induced cell death (AICD) than naive T cells using OVA-specific TCR transgenic DO10 mice and Fas-deficient DO10 lpr/lpr mice. We found that apoptosis was efficiently induced in a...

welsh onion (allium fistulosum l.) is one of the important vegetable crops in china. however, the seeds of this crop are short-lived and their vitality tends to be easily lost in the course of storage. the present study was conducted to elucidate the effects of welsh onion seed priming with potassium nitrate (kno3) on seed vigor and on other such related mechanisms during twelve months of stora...

in arid and semi arid, seedling emergence and establishment are key stages for final plant density in chickpea production. drought stress, especially at the end of the growing season, is one of the factors which decrease a main part of chickpea grain yield in these areas. therefore the aims of this study were assess to the effects of hydro priming and hormonal priming by gibberellin and abscisi...

Whooping cough remains a problem despite vaccination, and worldwide resurgence of pertussis is evident. Since cellular immunity plays a role in long-term protection against pertussis, we studied pertussis-specific T-cell responses. Around the time of the preschool acellular pertussis (aP) booster dose at 4 years of age, T-cell memory responses were compared in children who were primed during in...

The growth and performance of cowpea seedlings are negatively impacted by climate change the subsequent occurrence drought stress. Osmotic stress leads to formation reactive oxygen species, causing membrane breakdown, impairs metabolic activities. harmful effects osmotic can be reduced using seed priming techniques. Seeds var. Anaswara were treated with polyethylene glycol (PEG) ?-amino butyric...
