| Abstract: | Cold-resistance,pest & disease-resistance of Populus deltoides cv.‘Liaoyu 3’ were determined.The results show that the variety can resist the low-temperature of-47.84~-43.93 ℃.The incidence of resisting Dothiorella gregaria sacc.is lower than Populus×xiaozhuanica W.Y.Hsu Liang and get the most significant differences with control.The resistance of Cryptorrhynchus lapathi L.is obviously higher than parents and CK. |
