Table 1

Comparison of EL₅₀ values of leaves from RLD and transgenic Arabidopsis plants. EL₅₀values were calculated and compared by analysis of variance (25). EL₅₀ ± SE (n) are presented on the diagonal line for leaves from nonacclimated RLD (RLDw), cold-acclimated (7 to 10 days) RLD (RLDc), and nonacclimated A6, B16, and T8 plants. P values for comparisons of EL₅₀values are indicated in the intersecting cells.
