Effect of Nitrogen Addition and Weed Interference on Soil Nitrogen and Corn Nitrogen Nutrition
Duration of weed interference nitrogen uptake
2015/12/23
Weeds cause crop loss indirectly by reducing the quantity of resources available for growth. Quantifying the effects of weed
interference on nitrogen (N) supply, crop growth, and N nutrition may assi...

PEMV Pisum sativum heat shock proteins
2015/3/10
The physiological responses of pea plants during 40 days of compatible interaction with Pea enation mosaic virus
(PEMV) were evaluated. PEMV induces systemic changes in the concentration of phytohor...
Effect of mycorrhizal inoculation on growth, nitrogen fixation, and nutrient uptake in Cicer arietinum (L.) under salt stress
Cicer arietinum Glomus mosseae growth nitrogenase
2011/6/29
Most legumes in natural conditions form a symbiosis with arbuscular mycorrhizal (AM) fungi. AM fungi in saline soils have been reported to improve salinity tolerance and growth in plants.
