During the snow melting season of 1994, some exposed needles of Pinus pumila turned yellow in the alpine zone (2450 m) on Mt. Tateyama. However, relative water content (RWC) of the needles was far over the lethal RWC. Temperatures of soil and stems below snowpack remained near 0℃ during midday on 7...
