抄録
内容記述 A cross-cut disk of Picea which had survived from the Tunguska event in 1908,was used to reconstruct the past vegetation before and after the occurence of the event. The annul ring width had drastically decreased since AD 1909,the next year of the event, for 4--5 year, and then increased rapidly leading the decay variation observed usually in secondary growth of coniferous trees. The formar would be caused by the serious trauma in the organs such as leaf, branch, and root system due to the blast of the event. The uniseriate traumatic resin ducts were observed in the xylem formed in 1910 to suggest the occurrence of the trauma. The latter suggests the decrease of plant-sociological competition and the eutrophication of soil by forest fire. The extreme compression wood cells with spiral thickenings and cracks inside were observed in the wide rings formed in 1909-1913 possibly indicating the sudden change of light environment. Δ ^<14>C values of the annual rings formed in 1908-1910 were measured with Tandetron accelerator mass spectrometer at Dating and Materials Research Center, Nagoya University. Δ ^<14>C values were ranging from -28.2 to -1.5‰.
