Role of mycorrhizae:
They modify the physiology of the plant. They have an important role for three reasons:
• Biofertilizers: better use of soil resources
• Bioregulators: They homogenize the growth of plants and participate in the hormonal balance of the plant.
• Bioprotectors: They delay diseases and activate peroxidases (thicker wall allowing better resistance to diseases).
The benefits of mycorrhizal symbiosis with the vines are:
• Increased nutrient withdrawal
• Soil aeration
• Reduced incidence of root diseases
• Protection against environmental stress
• Glomaline = Glycoprotein produced by the fungus (important constituent of organic matter)
The roots of the mycorrhizae called hyphae can drain and transport nutrients to the plant and are capable of growing in the pores of the soil inaccessible to the roots
Moreover, this fungi is capable of taking Phosphorus and transporting it further than the roots.
Reciprocal profit between the vine and the mushroom:
The vine will transmit the sugar to the mycorrhizae and the fungi will transmit phosphorus to the vine. This phenomenon therefore allows plant growth as well as the increase in the efficiency of the vine to absorb the mineral elements of the soil
