Frost-induced reversible shrinkage of bark of mature subalpine conifers

Temporal and spatial patterns of stem and root radius changes were continuously measured on mature, subalpine Norway spruce (Picea abies (L.) Karst.) over 2 years. In addition, freezing experiments with stem segments of saplings were carried out in a climate chamber. The dynamics of the radius fluctuations were analyzed in relation to temperature profiles of air, bark, and soil. We found that b...

Physiological Evaluation of Pistachio Frost Damage Resistant Rootstocks

On 16th of March 2008, temperature decreased to -6ºC in some parts of the Kerman pistachio plantation area that was caused the heavy damage to pistachio growers. After the damage, some rootstocks were resistance to this temperature and no damage was interned to them. In the present study five rootstocks of resistant and five rootstocks of susceptible to frost damage were selected and evaluated ...
