Quantify Proline Accumulation to Assess Plant Stress Response
A Molecular Insight Into How Plants Are Coping With Stress
When plants are exposed to heat, drought, salinity, or heavy metals, they don’t always show visible symptoms— but internally, proline levels spike. Proline is a naturally occurring amino acid that plays a critical role in plant stress response. By measuring proline accumulation in leaf tissue, this test helps you evaluate early-stage stress, osmotic imbalance, and oxidative load
before damage is irreversible.
The Proline Stress Indicator Test
is ideal for research trials, agronomic diagnostics, and advanced crop management
under suboptimal growing conditions.
What This Test Measures
Free Proline Concentration
in fresh plant tissue
Reported in standardized units for comparative and diagnostic use
Serves as a biochemical marker for abiotic stress, including:
Drought
Salinity
Temperature extremes
Heavy metal exposure
General oxidative stress
Why Proline Matters
Osmoregulation
– Helps maintain water balance under drought or salt stress
Membrane Stability
– Prevents electrolyte leakage and cell damage
Antioxidant Role
– Reduces oxidative stress by neutralizing ROS
Stress Signaling
– Functions as a biochemical “alert” during environmental pressure
This test is especially valuable when paired with visual assessments, nutrient tests, or environmental data
for a complete plant health profile.
Sample Requirements
Fresh Tissue: 15–20 full leaves per sample ▪️ Double the amount for small-leaf crops (under 1 inch in size)
Packaging: Ship in paper bags only(plastic will cause degradation)
