Two-year-old Abies mayriana seedlings were planted in November in wooden boxes and subjected to different periods of soil freezing and exposure to sun and wind. When the soil was frozen, almost all terminal buds were damaged and 42% of the seedlings died. The moisture content of seedlings in frozen soil and exposed to artificial wind (3.26 m. sec. for 2 hr. daily from 30 Jan. to March) decreased strikingly after exposure to wind, and 50% of them died.
