文摘内容 18 clones of Populus deltoides and P. x euramericana were introduced from Italy, Turkey and domestic in 1986 and 1987 with the agreement of FAO. A completely random block design was applied and the seedling test and controlled afforestation trials had been held at Jinan City, Gaotang County and Juxian County, Shandong Province respectively. The results showed that two clones, namely S307-26 (P. deltoides cv.‘S307-26') and PE-19-66 (P. deltoides cv.‘PE-19-66’) performed well both in terms of adaptability and growth characteristics. The mean growth volumes (V) of single tree of S307-26 and PE-19-66 were 0.181 2 m3 and 0.164 9 m^3, which were 42.0 % and 29.2 % larger than that of I-69 (P. deltoides cv.‘Lux' 1-69/55 ) (CK), respectively, at the age of 5years at three experimental sites. Results of variance analyses and T test (LSD) for variables showed that above mentioned two clones were significantly different with 1-69 (CK). Further analyses found that both clones could be propagated easily and showed high resistance to poplar diseases, pests, drought, cold as well as strong wind, and had long growing period. Furthermore, mechanical properties were also better and fiber length was longer than that of 1-69 (CK). It was concluded that both S307-26 and PE-19-66 were ideal varieties for the establishment of fast growing poplar plantations, especially of the wood pulp forest plantations in the region。
