What is dormancy breaking? The role of Thiourea 99% in agriculture
What is dormancy breaking?
Dormancy is a period when crops temporarily stop growing, usually after harvest or in cold, dry seasons. During this period:
- Shoots and dormant buds stop growing
- The plant conserves nutrients to "rest"
- No new leaves or flowers; physiological activity slows down
Dormancy breaking is a technique that helps the plant come out of rest and resume growth and development.
