Figure 3:

Effect of temperature and light on A. glacialis embryonic growth inside seeds from Mt Stilwell-low (1927 m above sea level; a) and Mt Stilwell-high populations (2037 m above sea level; b), prior to germination. Data are plotted until germination begins, at which point sample size declines and the length of embryos inside remaining, ungerminated seeds was deemed not necessarily representative. Verticle bar in panel (a) denotes least significant difference.
