e1“the improved model can now capture the decrease in protein concentration that occurs in Indian wheat exposed to elevated O3”
e3“the simulated percentages ranged from 0.26 % to 0.38 % for lysine and from 0.13 % to 0.22 % for methionine”
e4“while the observed values were 0.16 % to 0.38 % and 0.14 % to 0.22 %, respectively”

Other claims from this paper (8)
- Method / resource The improved model captured the ozone-induced decrease in protein concentration of Indian wheat, relative to observed values.
- Method / resource The model captured grain protein, lysine and methionine concentrations reasonably well.
- Method / resource Simulated lysine ranged from 0.26 % to 0.38 % of dry matter, against observed values of 0.16 % to 0.38 %.
- Method / resource The model underestimated the decrease in lysine and methionine concentrations under ozone exposure by about 10 percentage points for methionine in both cultivars.
- Method / resource The model underestimated the ozone-induced decrease in lysine by 37 and 19 percentage points for HUW234 and HD3118, respectively.
- Method / resource Simulated relative yield loss was fairly accurate, with an average deviation of 2.5 percentage points excluding outliers.
- Mechanism The interdependence between parameters reduced the accuracy of simulated relative protein loss for grain and leaf.
- Recommendation Future experiments should measure N and protein concentrations in leaves and stems.
