All the four plant species responded to UV exclusion by a significant increase in plant height, leaf area, leaf biomass, total biomass accumulation and yield.
The micropropagated plants showed significantly higher values for leaf area, leaf length, leaf width and leaf dry mass.
For growth indices, such as leaf area ratio (LAR), leaf weight ratio (LWR), specific leaf area (SLA), and root shoot ratio (RSR) formulae by Hunt (1982), were used as shown: LAR cm 2 g - 1 = Leaf area Total biomass, LWR g g - 1 = Leaf dry weight Total biomass, Open image in new window RSR g g - 1 = Root dry weight Shoot biomass, SLA cm 2 g - 1 = Leaf area Leaf biomass.
Subscript 'i' represents either one of the leaf variables: leaf number, leaf area, leaf mass or leaf N. When i = leaf number or area, 'loss' is equal to litter (dead leaf) production.
The resistance of me crop to vapour transfer is affected by leaf area (number of stomata), leaf age and condition, and the degree of stomatal control.
Leaf area was measured by leaf area meter (LICOR model LI-3000, LiNEoln, NE) from plant parts separated as leaves during destructive mid-pod filling plant sampling and converted into leaf area index (m m−2) for statistical analysis.
As E is expressed per unit leaf area, values of KL have been scaled by leaf area.
For instance, Foley et al. [23] obtained LAI of each PFT by simply dividing leaf carbon by specific leaf area, and Sitch et al. [2] represented LAI by dividing leaf mass by crown area which was obtained from the allometric relationship between crown area and stem diameter.

Pruning, by decreasing leaf area, decreased water loss.
