Radiation fears growing as govt’ finds strangely deformed trees around Fukushima — Nearly 100% have ‘morphological defects’ — “Trees did not have a top bud, without which its growth cannot continue” — Effects worsening over time — Researchers prevented from doing studies… “so little data” (PHOTOS & VIDEO)

Asahi, Aug 29, 2015: … many fir trees near the plant, as well as other areas, had undergone “morphological defects.”… Fir tree boles normally extend upward with two or so branches arising from them horizontally each year. But this was not the case… researchers have difficulty doing surveys in the difficult-to-return zone due to high radiation readings. “There had been so little data on such areas,” [Prof. Tomoko Nakanishi, University of Tokyo] said.
NHK, Aug 28, 2015: Abnormalities found in trees near Fukushima plant… At the request of the [Environment Ministry, NIRS] analyzed fir trees… The results show that Japanese fir populations in the area showed a significantly increased number of morphological defects, including deletions of leader shoots of the main branch axis. The study shows that 98 percent of fir trees in a 3.5-kilometer area from the damaged plant have defects… The institute says the results indicate that radioactive materials emitted after the nuclear accident may have caused such morphological abnormalities.
Mainichi, Aug 29, 2015: … the top buds of many fir trees in heavily contaminated areas were missing…. In the area with the highest radiation level… 97.6 percent of the observed fir trees did not have a top bud — without which the trees’ growth cannot continue… The researchers say that these abnormalities have increased in prevalence since 2012.
Scientific Reports, Aug 2015: We investigated the morphological changes in Japanese fir… populations near the F1NPP showed a significantly increased number of morphological defects… significant increase in deletions of the leader shoots became apparent in those that elongated after the spring of 2012… defects were characterized by irregular branching… with a distinct deletion of the leader shoot that normally elongates vertically… high frequency of defects was observed in S1 [~3.5 km from FDNPP], where 125 out of 128 trees showed branching defects of the main axis… Compared to the whorls of 2010… the frequency of deleted leader shoots was significantly increased in the whorls after 2012… The frequency peaked in the whorls of 2013… Similar structures were also observed in the winter buds of 2015… there was an inexplicable 2-year time lag between 2011, the year with the highest radiation dose in the environment, and 2013, the year with the highest frequency of defects… of several potential factors, ionizing radiation is most likely to have increased frequencies of the morphological defect.
