Fig. 3. Temperature (A), relative humidity (B), and vapor pressure deficit (C) vs. plant height across all treatments and years. In year 2000 Temperature = 44.4 – Height x 19.8, r = 0.70, p < 0.016 Relative Humidity = –17.18 + Height x 120, r = 0.90, p < 0.001 and Vapor Pressure Deficit = 0.406 – Height x 0.41, r = 0.90, p < 0.001. In year 2001 Temperature = 44.7 – Height x 18.5, r = 0.58, p < 0.063 Relative Humidity = 112 – Height x 37.6, r = 0.58, p < 0.063 and Vapor Pressure Deficit = –0.114 + Height x 0.22, r = 0.57, p < 0.068.
