Fig. 3From: Functional relationship between photosynthetic leaf gas exchange in response to silicon application and water stress mitigation in sugarcaneEffect of water stress a–d) and different silicon levels (e–h) on the rate of transpiration (mmol H2O m−2 s−1) in sugarcane (Saccharum officinarum L. cv. GT 42) plants. Average mean values are each point (n = 5). Blue ovals denote the actual values and red lines show the predicted values. Parenthesis values indicate ( +) percent gain against stress.
