抄録

In this experiment, Freezing resistance was tested on 4 grass Species encased in ice. All species encased in ice suffered heavier injury than those not encased in ice by freezing treatment at -15℃ or -20℃. It was assumed that winterkilling of grasses were caused mainly by freezing injury, when they were encased in ice entirely in winter without snow cover in Nemuro〜Kushiro district.
