经10年的人工有性杂交和实生选种研究,选育出了陕酮一号和陕桐二号两个泡桐优良无性系。其材积生长比兰考泡桐分别快61.6%和42.9%;丛枝病发病率比兰考桐低20—40%左右,受大袋蛾危害较轻。
After 10 years of artificial sexual hybridization and selection of seedlings, two elite clones of Paulownia were screened out. Its volume growth rate was 61.6% and 42.9% faster than that of Paulownia paulownia respectively. The incidence of witches-broom disease was about 20-40% lower than that of Lantana konjac and was less harmful to big-bagged moth.
