Root Colonisation Questions

Question 1

Submit Answer 1

Answer 1

Only if the root grows so fast that initial colonisation from the surface propagules is reduced. Otherwise, the fungi will elongate along the root at about the same rate as would normally be observed with primary colonisation from all depths.


Question 2

Submit Answer 2

Answer 2

The rate of colonisation is a function of root growth and fungal spread. In a blocky soil, the rate of root elongation and fungal spread will be reduced, so that the rate of spread of colonisation is likely to be slower than in normal soils, but relative to root length, about the same.


Question 3

Submit Answer 3

Answer 3

Probably. If roots are formed, then the plant has stores of organic carbon which can become available to the fungi. If the fungi are adapted to growing in cool temperatures, then the host may gain increased mineral uptake, and thus benefit from the association in the usual manner.
