摘　　要：为了给品种区化和资源的育种利用提供理论依据，于１９９５－１９９６年在辽宁熊岳作者用外渗电导法、揭变观察法和恢复生长法测定了属于中国李、欧洲李、杏李、加拿大李、美洲李、包苏里李、樱桃李和李、杏杂种的３６个代表品种和类型的抗寒性。结果表明；（１）李的抗寒性表现出丰富的多样发表一多数李品种对低温的适应能力较强；（２）起 的生态２条件与品种的抗寒性密切相关；In order to provide the oretical basis for cultivar regionalization andbreeding vtilization ofplum germplasm resources, The hardiness of 36 typicalplum cultivars or types which belong to Prunussalicina, P. domestica, P. simonii, P. nibs, P. americana, P. ussuriensis, P. cerasdera and natural hybridbetween plum andapricot respectively have been determined by means of electronic conductivity, growthreinstatement and tissue browning evaluation methods with dormant shootsin 1995 ~ 1996 at Xiongyue,Liaoning. The results indicated: 1) the hardiness of plumcultivars show a great diversity and most of themhave strong adaptability tolow-temperature; 2) the ecological condition of original areas is closely relatedic the hardiness of plum cultivars; 3) the hardiness of the main plum specieses is: P. ussuriensis>P. americana> P. nigra> P. simonii> P. cerasdera> P. demestica> P. salicina; 4) shuili 3 is the mosthardy cultivar among P. salicina cultivars tested and is agood breeding material for hardy plum.
