Abstract
Mycorrhizae are mutualistic associations between plant roots and fungi.
These beneficial symbioses are ubiquitous in nature and almost all plant species have some form of mycorrhizal association with fungi.
Arbuscular mycorrhizas, or AM (formerly known as vesicular-arbuscular mycorrhizas, or VAM), are mycorrhizas whose hyphae enter into the plant cells, producing structures that are either balloon-like (vesicles) or dichotomously-branching invaginations (arbuscules). The current study explored the effects of arbuscular mycorrhizae inoculation on the growth and P and Zn absorption from the soil for wild jujube (Zizyphus spinosus Hu) seedlings grown in synthetic glass pots.
The pot had three compartments, a central compartment for root growth separated by 30 μm nylon mesh from two outer compartments for mycorrhizal hyphae growth.
For the check treatments the meshes were 0.45 μm to prohibit the fungi of the inner compartment into the outer.
The results showed that no colonization occurred in non-mycorrhizal wild jujube seedlings.
In the AM-inoculated plants, 82.5-87.0% of roots were colonized.
AM inoculation was able to significantly increase the fruit bearing shoots growth and improve P and Zn amount of plant.
With the increasing of soil P concentration in the outer compartments, hyphal uptake of P increased.
The percent of P absorption by the fungi were between 17.4 and 28.1%, those of Zn were between 13.1 and 33.1%.
