Accelerated Aging (AA) Test for Seed Vigor (त्वरित कालप्रभावन परीक्षण - Delouche & Baskin, 1973):

• Developed by Delouche and Baskin, the Accelerated Aging Test is a premier physiological stress test to assess seed storability and vigor.
• Seeds are exposed to high temperature ($40^\circ\text{C} - 45^\circ\text{C}$) and near $100\%$ relative humidity for a short period (48–72 hours), which artificially accelerates the physiological deterioration and aging process.
• The seeds are then germinated under standard conditions; high-vigor seed lots withstand accelerated aging and maintain high germination rates, whereas deteriorated lots show precipitous drops in germination.

Correct Answer: Option 3 (Accelerated aging test).
