摘　　要：对安徽省不同区域17个薄壳山核桃品种的花期进行了观测。结果表明:安徽省内薄壳山核桃的花期集中在4月20日~5月22日;薄壳山核桃雌雄异熟,多数品种的花期不遇;在17个品种(无性系)中,雄先型、雌先型分别占29.4%、70.6%,花期相遇、花期不遇分别占35.3%、64.7%;同一品种(无性系)在合肥、滁州、阜阳三地的花期受气候因子的影响较小,花期重合率在60%以上。按照异花授粉的原则,为3个区域不同薄壳山核桃品种提出了相应的授粉树配置方案。The flowering period of 17 varieties of Carya illinoensis from different areas of Anhui Province was observed.The results showed that the flowering period of in Anhui Province started April 20 and lasted until May 22.Carya illinoensis is dichogamy,and the protandrous and protogynous varieties accounted for 29.4%,70.6%,respectively.Flower synchronization and asynchronism accounted for 35.3%,64.7%,respectively.The flowering period of the same cultivar(clones)in Hefei,Chuzhou and Fuyang was less affected by climatic factors.Flowering consistency of most cultivar(clones)was more than 60%.According to the principle of cross-pollination,we proposed corresponding pollination combinations for different cultivars(clones)of C.illinoensis in Hefei,Chuzhou,Fuyang.
