Effect 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. S = standard error and r = correlation coefficient
