2. Growth – Private life of plants, BBC documentary (1995)

3. Cellular growth Photosynthesis products invested in: Respiration Biosynthesis proteins, amino acids, storage, other metabolites. Cell walls (predominantly polysaccharides) of new and expanding cells.

4. Cellular growth - cell division Cell cycle

5. Cellulaire groei - cell expansion Module 2

6. Whole plant Growth + C-gain in photosynthesis - C-loss in respiration

7. How to express growth?

8. How to express growth:

9. RGR depends on species and ontogeny:

10. Why do some plants grow faster than others?

11. How does a plant spend its daily fixed C? 15% Shoot respiration 15% Root respiration 70% Growth

12. Calculating plant growth RGR

13. Calculating plant growth RGR ULR

14. Calculating plant growth RGR LAR ULR

15. Calculating plant growth RGR LAR ULR PS A [C]

23. Breakdown of LAR: 1. SLA (m 2 leaf. kg -1 leaf) 2. LMF (g leaf . g -1 plant) *

24. In formula: PS A = daily photosynthesis = mol C / (m 2 LEAF . day) FCI = Fraction of fixed C Incorporated = mol C for growth / mol C fixed SLA = Specific Leaf Area = m 2 LEAF / kg LEAF LMF = Leaf Mass Fraction = g LEAF / g PLANT [C] = C-concentration = mol C / g PLANT

25. Interspecific variation in RGR:

26. Interspecific variation: LAR variables

27. High and low light leaves: High light Thick leaf  Low SLA Low light Thin leaf  High SLA

28. Interspecific variation: LAR variables

29. High and low light leaves: High light Thick leaf  Low SLA Low light Thin leaf  High SLA
