Abstract:: Watermelon cultivars ‘Sugarlee’ was used as material，the main vane length，fruit longitudinal diameter，fruit transverse diameter and fruit weight in the growth development period were measured.Growth and development regulation of main vane and fruit were reserched,mathematical model of growth and development of main vane and fruit were established in order to supply reference for high yield and high efficiency cultivation for watermelon.The results showed that there were two growth stages during the growth period.One was rapid growth stage，one was slow growth stage.There were five growth stages during the growth period，and exhibited slow-fast-slow-fast-slow rhythm.There were two growth peaks during the fruit growth period.Regression equation of days after flower and main vane，fruit longitudinal diameter，fruit transverse diameter and fruit weight were established by software.It showed that four regression equations coefficient correlation were high，and credibility was 99.99%.
