Spruce Nurseries Resistance at Extreme Temperature within Isuica Plantation

Because young trees are very sensitive to the climatic conditions, special attention must be paid to the environmental temperature. The aim of this study is to emphasize the effect of the low temperature on the spruce young trees within the particular case of Isuica plantation, and the protective effect of solid barriers against frost action upon these trees. The spruce trees less affected by the low temperature (2%) were located the area in the vicinity of the larch curtain bordering the General School building, while the most affected those located at 2 hours of walking (90%). Our study emphasized the vulnerability of spruce young trees against low temperature, and also the importance of placing vegetal and solid barriers, as buildings for protecting them against frost, in areas, which record low temperatures in winter.
