Cold Stratification for Seed Germination
- Seeds need cold and moist conditions for germination
- Seed dormancy is overcome by a winter period in the ground
- Cold, moist period triggers seed embryo growth
- Seeds are refrigerated in a medium for 1-3 months
- Soaking seeds in cold water before stratification can reduce the time needed
Warm and Cold Stratification Process
- Seeds needing warm and cold stratification require a warm area followed by cold
- Warm stratification requires 15-20°C
- Planting seeds in summer for germination in spring can meet requirements
- Some seeds may not germinate until the second spring
Additional Techniques for Seed Preparation
- Scarification improves seed permeability for germination
- Vernalization induces flowering using cold
