Question

Why is a mycorrhizal association necessary for pinus seed germination?

Answer 1

Seed germination:

1. Seed germination refers to the sprouting of seeds to give rise to whole new plants.
2. The seeds of the pinus trees possess hardened seed coats and thus, cannot germinate on their own.
3. The fungal bodies are present in association with their seedlings and protect the seeds from any diseases.
4. This association with mycorrhiza is crucial for the germination of pinus seeds.
5. It shields the seeds from becoming immature.
6. The seed provides sugars for the fungus and the fungus presents the seeds with water and essential minerals.
