Selection Of Phosphorus Deficiency-Resistant Tomato Genotypes And Characterization Of Phosphorus Efficiency Mechanisms By Morphological And Physiological Aspects

Low levels of available P in soils limit the plant production. Although total P concentrations are generally high in soils, because of some soil characteristics (low and high pH, high CaCO3, low organic matter etc.) in soils, it might be fixed in unavailable forms. Under P-limiting conditions, plant...
