Let ‘s Test Germination Rate of seeds!!
Formula for Computing Seed Germination Rate:
No. of Seeds Germinated
Total No. of Seeds
x 100 = % GERMINATION RATE
Example: 85 seeds germinated 100 seeds tested
.85 x 100 = 86% Germination Rate
Methods of Testing Seed Germination
Rag doll method - testing seeds using a towel.
STEPS
Get a firm towel
Wet the towel and allow free water to drip off for a minute.
Lay the wet towel flat.
Prepare the seeds

Use a bamboo stick and roll the towel
Spray water 2x a day to keep moisture

STEPS
Count the number of seeds germinated
Use the formula for computing the germination rate
Open the towel after 3 days
Petri dish method - testing seeds using a petri dish and tissue.
STEPS
