What hypothesis were the researchers testing in this study? What hypothesis were the researchers testing in this study? Sugar beet seedlings have a higher rate of fungal infection in heated soils. Soils can be treated to reduce their ability to suppress fungal disease in seedlings. Sugar beet seedlings have a lower rate of fungal infection in disease-suppressive soils. The disease-suppressive properties of soils are due to the activities of soil microorganisms.

What hypothesis were the researchers testing in this study? The disease-suppressive properties of soils are due to the activities of soil microorganisms.

Explanation:

Scientists wanted to know if microorganisms protect against crop disease. Researchers tried to figure out if microorganisms were responsible for the protective effects of disease-suppressive soils. The spil layer surrounding plant roots is called. When plants are attacked by fungal or bacterial pathogens, soil from the rhizosphere may protect them from future attacks.
