📘 Topic: Vernalisation
📗 Chapter: 8 – Plant Physiology
📙 Subject: Biology
🎓 Class: 11 (FSc 1st Year)
📚 Board: Punjab Board (New Biology Book 2025)
🧬 Definition:
Vernalisation is the process in which seeds, seedlings, or plants are exposed to low temperature for a specific period to induce early flowering. This ensures flowering at a favorable time and protects plants from environmental stress.
🌱 Importance of Vernalisation:
✔ Ensures timely flowering in winter crops
✔ Increases crop yield and productivity
✔ Helps plants adapt to temperate climates
✔ Plays an important role in plant breeding
✔ Improves quality and timing of harvest
