摘  要:
为了解欧美杨(Populus xeuramericana)在大连地区的抗寒性,以20个欧美杨无性系为研究对象,对其休眠枝含水量、电导率、MDA含量、Pro含量等指标进行了测定,结果表明:N177、02-01-119、03-05-156抗寒性较强,02-34-347、03-04-170、02-01-219抗寒性较差。该试验结果可以为欧美杨在辽南地区引种栽培提供理论依据。

摘  要:
In order to understand the cold resistance of Populus xeuramericana in Dalian area, 20 Populus xeuramericana clones were taken as the research objects, and the water content, electrical conductivity, MDA content, Pro content & other indicators of the dormant branches were measured. Result shows that: Populus xeuramericana ‘N177',P. xeuramericana‘02-01-119',P. xeuramericana ‘03-05-156' have strong cold resistance; Populus xeuramericana ‘02-34-347',P. xeuramericana ‘03-04-170',P. xeuramericana ‘02-01-219' have poor cold resistance; result can provide a theoretical basis for the introduction & cultivation of Populus xeuramericana in southern Liaoning Province.
