Fig 1. Effects of high temperature (HT) stress (34/26°C) on physiological traits.

Fig 1

Effects of HT on (A) leaf temperature (°C), (B) leaf chlorophyll (SPAD unit), and (C) maximum quantum yield of PSII (Fv/Fm, unitless) of wheat chromosome translocation lines and cultivars are presented compared to their performance at optimum temperature (22/14°C). Each bar represents LSMeans ± standard error of LSMeans of 24 observations (2 plants × 3 replications × 4 d). Genotypes with non-significant treatment effects are indicated by the same letters on top of the bars.
