Figure 3.

Box plots of Fv/Fm in R. lanuginosum from 11 different sites in Japan, after being exposed to short-term (12 days) temperature treatment ex situ. The median in the box plot is indicated by the horizontal line in the box, the box indicates the 25th and 75th percentiles and the bars indicate the 10th and 90th percentiles. Samples from Mt. Koma (altitude 500–1000 m above sea level) and Taisetsu (altitude 1700 and 1910 m above sea level). n = 4 (3 for altitude site 550). Effects of temperature treatments were non-significant (Table 3).
