Question
Define the term mycorrhiza. How are these associations affect a plant? Explain with examples.
✓
Answer
Mycorrhiza is a mutually beneficial or symbiotic association of fungi with roots of higher plants. Orchids grow as epiphyte on plants, have their roots associated with fungi right from the seedling stage.
Many orchids cannot survive without mycorrhizae associations. Many forest trees such as piles appear stunted if mycorrhizal associations are absent. In the presence of these associations, these plants absorb 2-3 times more nitrogen, potassium and phosphorus compared to without them.
