Response of stomatal conductance to water vapor (gs—mmol H₂O m⁻² s⁻¹) to water stress condition (55–50% soil moisture, moderate,a–d) and different silicon levels (e–h) 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
