Figure 1. Number of main-stem nodes of cotton above a sympodial branch with a first-position white bloom (bloom at anthesis) at various times throughout the 2003 and 2005 growing seasons in plots of two different temperature regimes. These temperature regimes means were averaged across two cotton cultivars (SureGrow 125 and SureGrow 125BR). Vertical bars denote LSD values at the 0.05 level and are present only when the differences between temperature regimes are statistically significant at the 0.05 level.
