摘要:杨树良种‘南杨’是通过人工控制授粉选育而成,雄株,为美洲黑杨种内杂种,其母本为50号杨,父本为36号杨。6年生平均胸径20.70cm,平均树高15.0m,单株材积0.1834m3,比对照中林46杨和I-69杨材积生长量分别提高22.3%和14.7%。树干通直,窄冠,速生,抗光肩星天牛,耐桑天牛,耐水涝。
P.deltoides ‘Nanyang’ , male clone and intraspecific hybrid of Populus deltoides hybid, was selected from the progeny of Populus deltoides CL.55/65’×P. deltoides CL. ‘2KEN8’ by the way of artificial control cross pollination. Average DBH, height and volum of six-years‘Nan’were 20.70 cm, 15.0 m and 0.183 4 m3, which were 22.3% and 14.7% more than ‘Zhonglin 46’ and I-69. The elite variety has the fine characteristic of up straight trunk, narrow crown, fast-growing, high resistance to Anoplophora glaberipennis, moderate resistance to Apriona germari and waterlogging tolerance.
