泡桐新无性系在沿海地区的遗传稳定性与适应性

A study on the genetic stability and adaptability of Paulowmia new clones in coastal areas in Jiangsu/

在江苏省沿海３种立地上对１０个泡桐无性系进行了生长的遗传稳定性与适应性研究，选出了１个优良无性系。该无性系稳定性强，具有广泛的适应性，与兰考泡桐和苏桐７０相比，其材积增长分别达到５６．７％和３８．ｏ％。

tabilitv and adaptabiiity of l0 Paulownia new clones were cultivated experiment in 3 coastal sites in Jiangsu,and an elite clone with higher stability and wider-ranging adaptability was elected,compared with P. elongata and P,jiang-suensis CL ‘70’,its volume increase reached 56.7% and 38.O%。
