| Abstract: | The microscopical observation and karyoltype analysis of embryo root cells of healthy Xingkai Lake pine and Xingkai Lake pine infected byCronartium quercuum were conducted. The results showed that the dividing phase of embryo root cells decreased and the viscidity of cells in dividing phase increased when Xingkai Lake pine was infected byC. quercuum. The karyoltype changed from the contract 4A to 4B, but the number of cell chromosome and karyoltype component did not change. (Responsible Editor: Zhu Hong) |
