Question:
Exposing seed to beneficial microorganisms is called as
Exposing seed to beneficial microorganisms is called as
Show Hint
Associate the prefix "Bio-" with living organisms. Since Trichoderma and Pseudomonas are living beneficial microbes used to coat and prime seeds, the process is called "Bio-priming."

The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Seed priming is a pre-sowing hydration treatment that initiates the early physiological processes of germination (imbibition and metabolic activation) without allowing the radicle to emerge.
Primed seeds exhibit rapid, uniform germination and improved seedling vigor.
Step 2: Detailed Explanation:
Let us define and distinguish the different seed priming techniques:
- Bio-priming: This is a specialized biological seed treatment where seeds are hydrated under controlled conditions in the presence of beneficial microorganisms (such as plant growth-promoting rhizobacteria like Pseudomonas fluorescens or biocontrol fungi like Trichoderma harzianum).
This process allows the beneficial microbes to colonize the seed coat.
Upon sowing, these colonized microbes establish rapidly in the rhizosphere, protecting the seedling from soil-borne pathogens and promoting early growth.
Let us review the incorrect options:
- Matrix priming (Matriconditioning): Uses solid insoluble carriers (like vermiculite or peat) to regulate water uptake.
- Hydropriming: Uses pure water as the hydrating agent.
- Halopriming: Hydrates seeds in dilute inorganic salt solutions (like $\text{NaCl}$ or $\text{KNO}_3$) to improve salt and drought tolerance.
Therefore, exposing seeds to beneficial microorganisms is defined as bio priming.
Step 3: Final Answer:
Exposing seed to beneficial microorganisms is called Bio priming.
