| Abstract: | "741","303","106" are superior white poplar clones which were bred and selected by hybridization.The regional tests at 8 selected sites that were monitored for 4 ~ 9 years show that "741" possesses the advantages of fast growth,high stability and wide adaptability while "303" and "106" possess fast growth in some regions.Improving the fertility of soil is an important measure to promote the growth of clones. |
