The total water content in the needles of spruce in the spruce forest Vaccinium myrtillus-sphagnum subzone of the middle taiga
The article presents the results of long-term observations of the moisture content in the needles of spruce in the spruce forest Vaccinium myrtillus-sphagnum subzone of middle taiga. It is noted, that at the beginning of the growing season overwintered needles the moisture level of low. Water content varies slightly during the growing season. Water deficit also varies slightly during the growing season and in different weather conditions. Indicators of water deficit in two to three times lower, than the known sub-lethal sizes. It is concluded, that small scope variations of water content and water deficit testify to the stability of the water regime of spruce.
