## 2.2 Applications of Plant Physiology ### Short-day Plants - Short-day plants respond to day lengths shorter than a certain maximum (less than about 12 hours) - Chrysanthemums are short-day plants and will bloom when day lengths range from 16 hours down to 7 hours, depending on the cultivar....

## 2.2 Applications of Plant Physiology ### Short-day Plants - Short-day plants respond to day lengths shorter than a certain maximum (less than about 12 hours) - Chrysanthemums are short-day plants and will bloom when day lengths range from 16 hours down to 7 hours, depending on the cultivar. ### Day-Neutral Plants - Day-neutral plants *do not* respond to day length, but must have sufficient growth to support flowering **QUESTION BANK** 1. To what extent can the knowledge of plant physiology help us to improve agriculture and horticulture? 2. Discuss briefly the role of plant physiology in: - Agriculture - Horticulture 3. How can the study of plant physiology be useful in agriculture and horticulture?
