Permafrost thaw in peatlands risks emitting vast stores of soil organic carbon (SOC) as greenhouse gases to the atmosphere, yet anoxic conditions and low peat quality may prevent rapid SOC loss. To assess differences anaerobic mineralization following vulnerability previously-frozen peat, we incubated (5° 14°C) from 15 depths ⁓6 m cores different sites including an intact permafrost plateau the...

Groundnut seed priming was performed with an aqueous solution of gibberellic acid (GA3) (0, 50, 100, and 150 ppm for 18h) and accelerated aging (96 h) was done prior to drought stress (-0.4, -0.6, and -0.8 MPa), then recovered. Investigated traits were germination percentage, mean germination time, germination rate, vigor index, plumule length, radicle length, seedling length, malondialdehyde c...

in order to evaluate the effect of priming on germination of black cumin under different levels of salinity, a factorial experiment on base of completely randomized design was conducted with three replications. the main factors consisted of five levels of priming (osmopraiming with kno3 (1 and 3%), salicylic acid (sa) (0.2 and 0.5 mm) and a hydropriming)) and four salinity levels (zero, 75, 125...

a pot experiment laid out in factorial arranged in completely randomized design with three replications was implemented to evaluate the effects of seed priming in ameliorating salinity stress in sesame (sesamum indicam l.) during seedling development and the early vegetative growth. factors included five priming treatments : control (non priming) , hydropriming, halopriming with nacl, kcl , cac...

in order to study the effect of on-farm seed priming and two bio-fertilizers on emergence and yield characteristics of chickpea, a factorial experiment was conducted in a randomized complete block design in hamedan with three replications in 2013. the factors consisted of phosphate fertilizer (0, 50 and 100 percent of recommended) bio-fertilizer (mycorrhizae, barvar2, both of them and no-applic...

Abiotic stresses spot lights the field crops at all growth phases and results in significant yield losses important crops, endangering safety of world's food supply. Numerous physiological, biochemical, molecular tactics have been examined by crop researchers to battle drought stress/water limiting stress, but current environment, these measures are meager. It is so claimed that plants can be p...

Seed priming improves vigor, but priming agents may differ greatly in their effectiveness. The present study was performed to unravel the physiological basis of vigor improvement by priming sunflower achenes with pre-optimized levels of hydrogen peroxide (H2O2), salicylic acid (SA), thiourea (TU), gibberellic acid (GA3), ascorbic acid (AA), sodium chloride (NaCl), freezing and heating. Most of ...
