摘要:

Throughout the study period (November 1985 to August 1987) the needle structure of damaged spruce trees(Picea abiesL. Karst.) was characterized by the reduction in size of chloroplasts at the cellular level and by a gradual advance of the damage at the tissue level. The injury type found in the investigated needles appears to be caused primarily by chronic exposure to a low concentration of oxone.
