This study was conducted to analyze the correlation between cultivation environment, cropping system, and the quality of cut flower in autumn-winter season chrysanthemum‘Jinba’, and to suggest the cultivation factors that can improve the quality of cut flower. It was examined for cultivation environment such as average day and night temperature, average day and night relative humidity, average day and night vapor pressure deficit (VPD), and integrated solar radiation of 4 farms planted in mid-October. Also, it was surveyed for cropping system such as cutting condition, growth period, irrigation method, soil chemical properties. Chrysanthemum ‘Jinba’ was harvested in order to investigate the quality of cutting of four farms, and then growth, chlorophyll content, and vase life of cut flowers were investigated. Based on these data, it was analyzed for the correlation between cultivation environment, cropping system, and quality of cut flower elements. In correlation between cultivation environment and quality of cut flower, the average night temperature showed a negative correlation with the growth of cut flower, and it was no correlation with other environmental factors. The vase life showed a negative correlation with the average day and night temperature and VPD, and a most positive correlation with the average day and night humidity. In correlation between cropping system and quality of cut flower, the cutting length, period of vegetative growth, daily irrigation amount, and total irrigation amount showed a less positive correlation, and leaf number of cutting and soil pH showed a most positive correlation with growth of cut flower. On the other hand, soil EC showed a less negative correlation, and days to flowering after light out showed a most negative correlation with growth of cut flower. The vase life of cut flower was not correlated with the cropping system factors.
