abstract for evaluating nacl salinity effect on some physiological and qualitative attributes of five winter canola cultivars, an experiment was conducted in a rcd base factorial in three replicates in greenhouse of east azarbaijan agricultural research center in 2008. five salinity levels as 0, 50, 100, 150 and 200 mm nacl treated as first factor on five rape seed (fornax, licord, elite, slm04...

The increasing commercial production and the broad usage of engineered nanoparticles (ENPs) have led to concerns over the potential adverse impacts of these ENPs on biota in natural environments. Silver nanoparticles (AgNPs) are one of the most important and widely used ENPs which enter natural ecosystems. In this study we examined the effects of AgNPs on growth and some physiological parameter...

turf is one of the most important ground covers and it is one of the main elements ofurban landscape design. plant growth regulators, such as growth inhibitors, are widelyused in turfgrass management to suppress shoot growth and inflorescences production.this experiment was conducted to determine the interactive effects of trinexapac-ethyl(te) and salinity on the growth, visual quality, and che...

The impact of water stress on antioxidant enzyme activities, proline, soluble sugars, and carotenoids contents found in Digitaria commutata Cenchrus ciliaris plants was investigated. Two different watering regimes were used over a period three months. Water decreased total chlorophyll content plants, but increased content. Interestingly, no change observed the quantum yield PSII photochemistry ...

Growth, development and plants productivity are usually affected by photosynthetic pigments activity. Magnetic fields are known to induce biochemical changes and could be used as a stimulator for growth related reactions including affecting photosynthetic pigments. The impact of magnetic field strengths on chlorophyll and carotenoids were investigated in this study through the use of date palm ...
