Drought is the cause of adverse environmental impacts on plant growth and crop yield. In this study, the effects of water deficit on plant molecular and physiological responses were investigated using two cultivars (namely, Sardari and Zarin) of bread wheat selected based on the results of a three-year research. For the purposes of this study, they were grown in plastic pots containing field so...

Environmental pollution consists of different types of pollutants in air, soil, and water. Due to the fact that plants can respond to environmental pollution, they can be used as bio-indicators for environmental monitoring. Air pollution in areas with oil and gas refineries nearby is an important problem. This study aims to survey the effects of gas refinery air pollutants on Conocarpus erectus...

This study examined if pre-germination altered the water content and water activity, contents of phytate, total phenolic, (±)-catechin, quercetin and total antioxidant capacity of almond  (Prunus dulcis)kernel. Raw almond kernels were submerged for 15 hours in water, 0.02 mol dm-3 phosphate buffer solution (pH 5.0) and 0.02 mol dm-3 phosphate buffer solution (pH 7.0) at 25 and 40ºC, respectivel...

this study was conducted to evaluate the effect of water stress on the growth and mineral concentrations in the leaves and roots of four pistachio seedling rootstocks including pistacia vera ‘badami-riz-zarand’, ‘ghazvini’, ‘sarakhs’ and p. mutica. irrigation treatments were 100% etc (control), 65% etc (medium stress) and 30% etc (severe stress) applying for 75 days on four months old pistachio...

Canopy water content is a dynamic quantity that depends on the balance between water losses from transpiration and water uptake from the soil. Absorption of shortwave radiation by water is determined by various frequencies that match overtones of fundamental bending and stretching molecular transitions. Leaf water potential and relative water content are important variables for determining wate...

Background: In many developing countries, numerous brands of bottled water and the relatively cheaper counterpart, sachet water, can be found in all cities, towns, and even villages. This study assessed the concentrations of some phthalates and metals in bottled and sachet water sold in Lagos, Nigeria. Methods: Fifteen pieces of plastic bottled water and 15 pieces of sachet water were randomly...
