Strong antioxidant activity of Pelargonium graveolens is well known. The question addressed in this study was whether different concentrations of exogenous ascorbic acid (AsA) and iron (Fe) were able to influence antioxidant activity and total phenol content (TPC) of geranium. Thus, three levels of Fe (0, 20 and 40 µM) and three levels of AsA (0, 1 and 2 mM) in nutrient solution were c...

The global population is expected to reach 7 billion by the year 2013. How are we going to feed the world, prevent further degradation of our environment, and begin to reverse the damage that our increasingly industrialized society has already caused to the biosphere? We argue that plants with enhanced mineral acquisition and storage strategies can help us to achieve these goals. For example, w...

The increase in worldwide population observed the last decades has contributed to an increased demand for food supplies, which can only be attained through improvement agricultural productivities. Moreover, practices should become more sustainable, as use of chemically-based fertilisers, pesticides and growth stimulants pose serious environmental problems lead scarcity finite resources, such ph...

To survey the effects of flooding during the reproductive growth stages of aerenchyma formation and ethylene production in soybean cultivar DPX experiment  the completely randomized factorial was in 2012 in Gorgan University of Agricultural Sciences and Natural Resources. Factors examined include nutrition levels in three levels (1 - inoculated with bacteria JaponicumBradyRhizobium 2 - non-inoc...

since the use of antibiotics in animal feeds has been banned, researches on alternative natural products that modulate ruminal fermentation have been intensified. natural compounds such as plant extracts have been considered to be replaced antibiotics as safe and sustainable alternatives. plant extracts especially essential oils and saponins have strong antimicrobial, antiparasitic, antiprotozo...

in order to assess the effect of salinity constraint on some agro-physiological and biochemical traits in medicago sativa l., four alfalfa populations (tafilalet 1, tafilalet 2, demnate and tata), originated from mountains and oasis of morocco, were tested. the plants were grown under greenhouse conditions in pots filled with sand and peat under three salt treatments (0, 100 and 200 mm nacl). t...

Considered to play an important role in plant mineral nutrition, arbuscular mycorrhizal (AM) symbiosis is a common relationship between the roots of a great majority of plant species and glomeromycotan fungi. Its effects on the plant host are highly context dependent, with the greatest benefits often observed in phosphorus (P)-limited environments. Mycorrhizal contribution to plant nitrogen (N)...
