Q & A

What is mycorrhiza, and why is it important?

Mycorrhiza is a symbiotic relationship between fungi and plant roots. It is important because it helps plants absorb water and essential nutrients, especially phosphorus, and provides them with carbohydrates produced through photosynthesis. This underground interaction is crucial for plant growth, ecosystem balance, and agricultural sustainability.

How does mycorrhiza contribute to plant health?

Mycorrhiza enhances plant health by improving nutrient absorption, especially phosphorus and nitrogen. It also increases plant resistance to environmental stresses like drought, pathogens, and heavy metals in the soil. Moreover, it helps in strengthening the root system and promoting better growth, particularly in nutrient-poor soils.

What are the two main types of mycorrhiza, and how do they differ?

The two main types of mycorrhiza are ectomycorrhiza and arbuscular mycorrhiza (AMF). Ectomycorrhiza forms a network on the surface of the plant roots without penetrating root cells, often found in forest ecosystems. AMF, on the other hand, penetrates root cells and forms structures like arbuscules and vesicles to enhance nutrient exchange.

How does mycorrhiza help in phosphorus absorption?

Mycorrhiza plays a crucial role in phosphorus absorption by breaking down phosphorus compounds in the soil that are otherwise inaccessible to plant roots. The fungal network extends deep into the soil, absorbing phosphorus and delivering it to the plant roots.

Why is phosphorus critical for plants, and how does mycorrhiza address its scarcity?

Phosphorus is essential for plant growth as it is a key component of DNA, RNA, and ATP, which are vital for energy transfer and cell function. However, phosphorus is often limited in soil, and mycorrhiza helps by facilitating its absorption from otherwise unavailable sources, reducing the need for chemical fertilizers.

What is the role of mycorrhiza in improving soil structure?

Mycorrhiza improves soil structure by enhancing soil particle aggregation, which increases soil aeration and water retention. This contributes to better soil health, particularly in degraded or compacted soils.

How does mycorrhiza contribute to drought resistance in plants?

Mycorrhiza helps plants survive drought by storing water in the fungal network, which acts like a sponge. This allows the plant to continue receiving water even in dry conditions, helping to reduce the risk of crop failure due to water stress.

What is the significance of mycorrhiza in sustainable agriculture?

Mycorrhiza is significant in sustainable agriculture as it reduces the need for chemical fertilizers by enhancing nutrient absorption and improving soil health. It also helps in reducing water usage and increasing plant resilience against pests and diseases, contributing to more eco-friendly farming practices.

How does mycorrhiza protect plants from root pathogens?

Mycorrhiza protects plants from root pathogens by producing antimicrobial compounds that inhibit the growth of harmful microorganisms. Additionally, the fungal network can occupy spaces around the root, preventing pathogens from accessing the plant roots.

What is the role of mycorrhiza in ecological restoration?

Mycorrhiza plays a key role in ecological restoration by improving soil fertility and structure in degraded lands. It aids in the rehabilitation of soil after mining or deforestation and supports the growth of pioneer plants, accelerating ecological succession and promoting the restoration of stable ecosystems.
