摘　　要：为扩大珙桐在城市绿地中的应用,开展了珙桐在苏州地区的引种驯化研究。结果表明,珙桐在苏州地区的引种栽培取得了一定进展,引自恩施、雅安、绵阳的珙桐苗木成活率有差异,引自绵阳的珙桐苗木成活率较高;储藏1年后,珙桐种壳于3月中旬自然腐烂,发芽率达65%;引自这3个区域的珙桐苗木物候期趋于一致;引种的珙桐共出现金龟子、蜗牛、蜘蛛、茎腐病、烂根等5种病虫害。In order to expand the application of Davidia involucrata in urban green space,the study on introduction and domestication of Davidia involucrata in Suzhou area was carried out.The results showed that the introduction and cultivation of Davidia involucrata had made some progress in Suzhou area.The survival rate of Davidia involucrata seed-lings from Enshi,Ya′an and Mianyang were different,and the survival rate of Davidia involucrata seedlings from Mianyang was higher.After a year of storage,the Davidia involucrata seed shell rotted naturally in mid-March,with a germination rate of 65%.The phenological period of Davidia involucrata seedlings from these three regions tended to be the same.Five kinds of pests and diseases were found in the introduced Davidia involucrata,such as beetle,snail,spider,stem rot and root rot.
