Mineral Uptake Questions

Question 1

Submit Answer 1

Answer 1

The plant will have adequate P concentrations in shoot tissue, and is likely to retain sufficient AM colonisation to maintain Zn uptake. However, if the plant reduces AM colonisation, Zn deficiency may result, reducing rates of plant growth.

Question 2

Submit Answer 2

Answer 2

The plants will become increasingly deficient in P, Zn and Cu, and Mn toxicity signs may develop depending on the mineral status in the soil. K deficiency is possible though rare in reality.

Question 3

Submit Answer 3

Answer 3

Most dependent plants are competitive species, though the relationship is not simple. Crop species are highly dependent on soils with high levels of mineral nutrients, and thus might be expected to be ruderal. Further, the use of fertiliser under breeding conditions may remove genes responsible for responsiveness to AM.
