Question

Match List-I with List-II

Choose the correct answer from the options given below:

• (A) - (IV), (B) - (I), (C) - (III), (D) - (II)
• (A) - (IV), (B) - (I), (C) - (II), (D) - (III)
• (A) - (II), (B) - (III), (C) - (I), (D) - (IV)
• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

Remember that "Halo" refers to salt (salinity stress), "Hydro" refers to water (arid/dry soils), and "Bio" refers to living beneficial microorganisms.
This botanical terminology makes matching options straightforward.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Seed priming is a pre-sowing physiological treatment that controls seed water uptake.
This controlled hydration initiates early metabolic processes without permitting full radicle emergence.
Various priming methods are customized depending on the environmental constraints of the target site.

Step 2: Detailed Explanation:
- (A) Hydropriming: This method involves soaking seeds in pure water followed by drying.
It is a simple, cost-effective method widely used in arid regions.
This treatment enhances seed performance and accelerates emergence under dry soil conditions. Thus, (A) matches (IV).
- (B) Halopriming: This method involves soaking seeds in inorganic salt solutions like \( \text{NaCl} \), \( \text{KNO}_3 \), or \( \text{MgSO}_4 \).
This treatment activates metabolic pathways that help seeds tolerate osmotic and ionic stresses.
It is highly effective for improving crop performance under salinity stress. Thus, (B) matches (I).
- (C) Matrix priming (Solid Matrix Priming - SMP): This method involves mixing seeds with a solid, insoluble carrier and a limited amount of water.
Typical carriers include vermiculite, diatomaceous earth, peat, or clay.
This mixture controls water uptake by the seeds through matric forces. Thus, (C) matches (II).
- (D) Bio priming: This method combines seed hydration with biological inoculation.
The seeds are treated with beneficial biocontrol agents like Trichoderma spp. or Pseudomonas fluorescens.
This treatment allows these beneficial microbes to colonize the seed coat, protecting it from soil-borne pathogens. Thus, (D) matches (III).
Matching these pairs results in: (A) - (IV), (B) - (I), (C) - (II), (D) - (III).

Step 3: Final Answer:
The correct matching sequence corresponds to option (B).
