Abstract:
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.
