摘　　要：以内蒙古、辽宁两省(区)16个县(市)的24份文冠果(Xanthoceras sorbifoLia Bunge.)种子为试验材料,以大田育苗为试验方法,以出苗率、苗木质量为依据分析种子来源对神东矿区文冠果育苗的影响。通过方差分析,结果证明种子来源对苗木初期生长状况有极显著的影响;以出苗率、成苗率及6月初9、月底生长量为依据,进行灰色关联分析,结果表明伊金霍洛旗新庙的文冠果种子与理想种源的关联度最大,γ=0.882 2,为参评种源中的最优种源;证明地域因素对文冠果成苗率有显著影响,因此,在条件许可的前提下,育苗时最好选择当地的种子。Collecting 24 kinds of Xanthoceras sorbifoLia Bunge.seeds from Inner Mongoli and province totally 16 districts as the research objects,Sowing the seeds directly into the field as a test method,analysis the influence of different seed sources on the cultivation of seedling of Xanthoceras sorbifoLia Bunge.in Shendong Mining Area.According to the analysis of variance showed that the seed source has the extremely remarkable influence to the early growth of seedlings;With the rate of seedlings emergence,seedling survival,and the growth at the beginning of June and at the end of September as the bases for the gray connection analysis,The result indicated that the seed source of Yijinhuoluoqi Xinmiao had the evenly high correlation with the ideal seed source,it converting station the best seed source of all with γ=0.882 2.In conclusion,the geography factor played a significant role in the rate of seedling emergence of Xanthoceras sorbifoLia Bunge.Hence,if the condition allows,the local seeds will be the best choice for the culture of seedling.
