Fig. 1 Daily average temperature regimes for the five treatment conditions represented by five lines in the curves. From the bottom up: the first thin solid line represents 2°C below the 1995 ambient temperature; the next bold line represents the 1995 ambient temperature; the following thin, bold, and thin lines represent 2, 5, and 7°C warmer than the 1995 ambient temperature treatments. An overall bold line not closely following the curve pattern indicates the 42-yr long-term average daily temperature for Stoneville, MS (a site representing the U.S. Mid-South during that time frame; Reddy et al., 1997). Plants were harvested as they reached 50% open bolls; the higher temperature treatments were therefore harvested earlier than the cooler treatments
