What is the role of mycorrhizae in nursery plants?

Mycorrhizae play a crucial role in enhancing nutrient absorption and improving plant health, making it the correct answer. These beneficial fungi form a symbiotic relationship with the roots of nursery plants, extending the effective root surface area. This extension allows the plants to access water and essential nutrients, particularly phosphorus, which are often limited in soil.

Additionally, mycorrhizal associations can help improve soil structure, enhance drought tolerance, and increase resistance to root pathogens, leading to overall improved plant health. Through this enhanced nutrient uptake and the positive influence on plant resilience, mycorrhizae contribute significantly to the growth and vitality of nursery plants, ensuring that they are healthier and better equipped for their environment.
