An experiment was undertaken to evaluate the effects of three-day periods of high and very high temperatures (32/24C and 37/25C day/night temperatures, respectively) at different stages of seed development (10, 20 and 30 days after flowering) on the fatty acid composition of a high erucic acid rapeseed (HEAR) and a mid oleic acid canola (MOAC) breeding line (“cultivar”). The earliest formed see...

background and objectives: drought stress is one of the most important environmental factors reducing growth and yield of crops, especially in arid and semiarid regions of the world. during drought stress, nutrient uptake diminishes due to rising of solute concentrations and so increasing of osmotic potential in the root zone. with increasing soil ph, micronutrient uptake decreases more than ot...

in a sustainable agriculture system, application of the fertilizers which are nature friendly and suitable for plants is essential. this becomes more important when dealing with medicinal plants. therefore, a factorial experiment in a randomized complete block design with three replications was set up in the 2012-2013 on nigella sativa l. treatments were nano­fertilizer (pharmks®) (at 2 levels ...

Japanese horse chestnut (Aesculus turbinata) seed extract inhibits the activity of cyclooxygenase (COX), but its active constituents have not been identified. In the present study, COX inhibitors were isolated from the hexane extract of this seed by means of 4 steps of liquid chromatography and were identified by gas chromatography/mass spectrometry and nuclear magnetic resonance. The COX inhib...

The quality of edible seeds for human and animal nutrition is crucially dependent on high zinc (Zn) and iron (Fe) seed concentrations. The micronutrient bioavailability is strongly reduced by seed phytate that forms complexes with seed cations. Superior genotypes with increased seed Zn concentrations had been identified, but low micronutrient seed levels often prevail when the plants are grown ...
