Development of Mycorrhiza and their Influence on Nutrient Status, Plant Growth and Innate Immunity

Efficiency of Mycorrhizal Fungi with Different Levels of Phosphatic Fertilizer on Growth of Piper mullesua Plantlets

“…Like all other mineral nutrients, P enters the biosphere predominantly via the pedosphere through the root system of plants, where it is absorbed as inorganic orthophosphate (Pi), which is preferred form taken up by plants (Bucher, 2006). Phosphorus that exist in the environment as Pi, primarily evolved in inert complexes with cations such as iron phosphate (FePO 4 ) and aluminium phosphate (AlPO 4 ), and in organic molecules such as lecithin and phytate, the latter of which can account for up to 50% of total soil organic Pi (Brinch-Pedersen et al, 2002). Roots take up P as inorganic phosphate (Pi), and this leads to the creation of Pi depletion zones around them, a phenomenon that can lead to P deprivation.…”
