abstract field experiment was carried out at the ferdowsi university research field, mashhad, iran during 2006-2007, to determine how much effective the n-fertilization is, to find out the most suitable plant density which could be used in chamomile (matricaria chamomilla l. asteraceae) to increase the yield of anthodium flowers and content of essential oil. the experimental design was as two f...
Abstract: Sulphur dioxide (SO2) is one of the main air pollutants that can cause imbalance in growth and physiological function of plant in high concentrations. Rhizobium-plant symbiosis can cause increasing in plant resistance to abiotic and biotic stresses in addition to increase growth of plant. In this study, effects of Rhizobium (native and standard strains) on leaf anatomical parameter...
