Tree Physiology 24, 1209-1220 6CO2 + 6H2O + energy (from sunlight) → C6H12O6 + 6O2 The carbohydrates are manufactured by plants during the process of photosynthesis The primary product of photosynthesis is Glucose which is the source of carbohydrates like cellulose, starch etc. Main soluble sugars Glucose Fructose Sucrose (n is the number of repeating glucose units and ranges in the 1,000's) Starch Starch is a long, straight chain of glucose units. Starch is the principal polysaccharide used by plants to store glucose for later use as energy. Glucose St h arc C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + energy Carbohydrates are broken down during the process of metabolism to release energy Total non-structural carbohydrates (TNC) Represent a tree’s capital for growth: TNC = Carbon gain (photosynthesis) – Carbon loss (respiration) = total soluble sugars + starch Li MH et al. 2002. Trees 16, 331-337 Non-structural carbohydrates (NSC) = Glucose + Fructose + Sucrose + Starch
