The genetic consequences of irradiation were studied in a Scots pine population from a region contaminated as a result of the Chernobyl meltdown. Mutations of isozyme loci were not detected in seeds collected from trees of the first post-meltdown generation in 2004. The frequency of cells with chromosome aberrations in the root meristem of seedlings grown from the seeds did not differ from the control level. A deviation from the expected ratio 1:1 was observed for some isozyme alleles in endosperms of seeds obtained from heterozygous trees.
对来自因切尔诺贝利核事故熔毁而受污染地区的苏格兰松种群的辐射遗传后果进行了研究。2004年从熔毁后第一代树木采集的种子中未检测到同工酶位点的突变。从这些种子培育出的幼苗根分生组织中具有染色体畸变的细胞频率与对照水平没有差异。从杂合树木获得的种子胚乳中，一些同工酶等位基因出现了偏离预期1:1比例的情况。
