The growth characteristics and active compounds of plants are influenced by various environmental factors, including light, temperature, soil, and precipitation. These factors interact with each plant in a unique way. In this study, we collected fruit and soil samples from 17 cultivation sites in October 2020 to investigate the relationship among environmental factors, growth characteristics, and active compounds of <i>H. dulcis</i> seed and fruit. We developed an optimized method for quantifying active compounds using ultra-performance liquid chromatography and performed correlation analyses with the surveyed environmental factors. Results showed that the size and fresh weight of <i>H. dulcis</i> fruits were positively correlated with exchangeable Mg, Na, and silt texture proportion in the soil. The temperature was positively correlated with sugar content in the fruits but negatively correlated with fruit weight, and precipitation was negatively correlated with fruit size. Results also showed a positive correlation between the active compounds and growth characteristics such as fruit length, seed number per fruit, and fresh weight. The results of this study can be used as basic data for the cultivation and quality control of <i>H. dulcis</i> fruits.
