Study on Method for Investigating Nutrient Changes in the Hyphae-soil Interface |

Abstract: |
VA mycorrhzal infection plays a very important role in plant nutrition,especially on soils low in fertility.The mycorrhizal hyphae are in fact the absorbing organ for nutrient acquisition from soil.The hyphal uptake was expected to induce changes in nutrient content in the soil near the hyphae(hyphae-soil interface).In order to investigate the effect of mycorrhizal hyphae on nutrient distribution in the hyphae-soil interface,a pot experiment system was developed.The pot was distinctly separated in root,hyph... |
