- Abstract
【Objective】 The aim of this study was to compare the fruit drop dynamics, fruit characters and seed quality among three shapes of Xanthoceras sorbifolium, to study the effect of inflorescence regulation, and to explore the relationship between tree structure and fruiting characters, so as to provide reference for tree shape culture and flower and fruit management of young Xanthoceras sorbifolium. 【Methods】 The two experiment factor design was adopted, through field experiment, the results were analyzed by ANOVA, multiple comparison, principal component analysis and correlation analysis.【Results】 The number of inflorescences in the cluster of main branches shape was 33, which was significantly higher than that in the other two tree shapes, it's final fruit set percentage was 28%, which was significantly higher than that in natural open-centeralized shape, and most fruit and seed characters were better than the central leader tree shape significantly. When cut off the top of inflorescence, the fruit drop rate decreased from 56% to 41% in fruit growth period, and the thickness of shell under cut off inflorescence'top and emasculation was 6% less than remove inflorescence treatment. The tree structure indexes related to seed yield were ground diameter (r= 0.238) and branch diameter (r= 0.350), and the inflorescence flower indexes related to seed yield were inflorescence site (r= 0.204), flower number (r= 0.343) and pregnant flowers ratio (r=0.322). The tree structure index related to seed quality was branch number (r=0.351), and the inflorescence flower indexes related to seed quality were inflorescence remove rate (r=- 0.436) and pregnant flowers ratio (r= - 0.216).【Conclusion】 The tree shape has a general effect on inflorescence,fruit and seed characters of the young trees of Xanthoceras sorbifolium.The 1,000 seed weight and kernel percentage of the cluster of main branches shape are higher than that of the central leader tree shape significantly.The inflorescence regulation treatment has significant effect on reducing the fruit drop rate in fruit growth period, reducing the shell thickness and improving the seed production rate.
