Regression analysis parameters and R² or r² for purple basil, sage, spearmint, and sweet basil branch number, height, maximum quantum yield of dark-adapted leaves (F_v/F_m), leaf area of four most recently fully expanded leaves, dry matter concentration (DMC), leaf mass fraction, and fresh mass in response to mean daily temperature (MDT;°C) and daily light integral (DLI; mol·m^‒2·d^‒1).

All models are in the form of: f = y0 + a*MDT + b*DLI + c*MDT2 + d*DLI2 + e*MDT*DLI.
