Table II. Canopy K_L and b for 16 cultivars of wheat.

Crops were grown in the field at CF during the 2006–2007 (CF07) and 2007–2008 (CF08) growing seasons and at SB during the 2006–2007 growing season (SB07). Data are means ± se for two treatments × three independent replicates. P values of the main effects and interactions from split-plot ANOVAs for the 16 cultivars at CF are reported.
