摘  要:
以杨凌苗圃5a生30株文冠果为试材,对其物候、开花习性和结实情况等进行了观察分析。结果表明:杨凌地区文冠果果实从形成到成熟约经历90d,与该区立地条件相同或相近的地方均可以引种至大规模发展;文冠果的孕花比例很低,平均为17.35%,可采取花性转化的调控措施;果实在树体空间分布情况:在不同冠向结果量中,南向结果量最多,占总结果量的34.8%;在不同冠位结果量中,树冠上部结果数量占总结果量的45.8%,84.3%的果实都位于树冠的中上部;在不同枝龄结果量中,1~2a生枝条结果甚少,4a生枝条结果量占比例最大。果实50%以上为单生,3裂果实占全部调查果实数量的95.3%。

摘  要:
Taking 5-year-old 30 Xanthoceras sorbifolia in the nursery of Yangling as materials,the phenophase,blooming habits and fruiting rules were observed and analyzed.The results showed that the fruit of Xanthoceras sorbifolia of Yangling need about 90 days from shaping to ripening,they could be planted to those places where had the same or similar conditions;the proportion of fertile flower was very low,only 17.35%,so the regulation and control measures of flower sex transformation could be taken;the distribution of fruits on the tree was as follows:south had the most fruits which was 34.8% of total amount;for different position of the tree-crown,45.8% of fruits were on the upside and 84.3% of them were on the upside and middle part of the tree;for different age of branches,4-year-old branches had the most while 1-year-old or 2-year-old branches rarely.More than 50% of the fruits were solitary and 95.3% of the total amount were dehiscent fruit which with three lamellas.
