To investigate the light conditions required for the growth and development of Cucurbita ficifolia.and clarify the photoperiod required for its reproduction in northern regions,this study aims to facilitate its genetic improvement and breeding utilization in different regions,especially in northern regions.In this study,different photoperiod treatments were applied to C.ficifolia seedlings to investigate their effects on the strong seedling index,root-to-shoot ratio,soluble protein content,chlorophyll content,and late flowering habits.The results showed that the C.ficifolia seedlings in the 16 h long-day group had the highest strong seedling index.The soluble protein content was highest in short-day treatment of 8 h and 30 d.Short day treatment of 8 h and 20 d significantly increased the chlorophyll content,medium day treatment of 12 h and 20 d promoted the development of female and male flowers of C.ficifolia.In summary,long-day treatment is beneficial for cultivating strong seedlings of C.ficifolia,while middle-day and short-day treatments are beneficial for the formation and development of the flower organs.The optimal treatment is 12 h of light per day for 20 d.
