On the Diversity of Osmanthus Fragrans Phenotypic Traits in Different Functional Areas of University Campus
In order to explore the influence of environmental factors in different functional areas on the phenotype traits of Osmanthus fragrans,and to provide a research basis for plant cultivation,applica-tion and landscape improvement.This experiment studied the leaves and seeds of Osmanthus fragrans in six functional areas of Huangshan University to study the response of phenotypic traits and environmen-tal factors.The results show that the phenotypic characteristics of O.fragrans leaves and seeds in differ-ent functional areas vary significantly;the variation coefficient of leaf dry material mass of O.fragrans leaves in different functional areas is less than 10%;the soil EC value is negatively correlated with specific leaf area,seed longitudinal diameter,seed dry weight and seed thousand grain weight,while the soil temperature is negatively correlated with seed longitudinal diameter,seed dry weight,seed mass in-dex and thousand kerner weight.O.fragrans leaves showed a significant negative correlation between specific leaf area and leaf dry mass.The results presented above indicate that the phenotypic traits of O.fragrans in different functional areas are affected by environmental factors.
