Fig. 1From: Phenomics for photosynthesis, growth and reflectance in Arabidopsis thaliana reveals circadian and long-term fluctuations in heritabilityDistribution of photosystem II efficiency (ΦPSII) in a phosphate deficient Arabidopsis. a False colour ΦPSII image of a phosphate deficient plant, the scale bar on the right shows ΦPSII values from 0 (black) to 1 (green). b Image a plotted as a histogram of pixels at specific ΦPSII values. The distribution is bimodal hence the mean value fails to aptly represent the plant’s phenotypeBack to article page
