mycorrhizal symbiosis increase nutrient uptake and enhance plant growth by elaborating root system. the positive effects of mycorrhizal symbiosis on the growth, physiology and ecology of various plants have been recognized. the symbiotic relations between mycorrhizal fungi and date palm with regard to nutrient uptake by this plant have not yet been explored and studied in iran. this project was...

BACKGROUND AND AIMS High Al resistance of Rumex obtusifolius together with its ability to accumulate Al has never been studied in weakly acidic conditions (pH > 5.8) and is not sufficiently described in real soil conditions. The potential elucidation of the role of organic acids in plant can explain the Al tolerance mechanism. METHODS We established a pot experiment with R. obtusifolius plant...
