Taking purple passion fruit as material，the growth dynamic under greenhouse cultivation condition was studied.The results showed that，under the solar greenhouse cultivation conditions in Liaoning Xiongyue，the new shoots grew fastest in mid-June to mid-July；the leaves rapid growth time was mid to late-August about 15 d；the flowering plants in June accounted for 92% of the total annual，the beginning flowering section of level 1 tendril was more scattered，1~4 section beginning flowers accounted for 50.3%；the beginning flowering section of level 2 tendril mainly concentrated in section 6，section 11 above less；setting fruit quantity in July was 48.8% of full-year quantity；most fruit riped in September，about 50%~70% of ripe fruit throughout the year；the fruit grew rapidly in the first two weeks，fruit was strongly influenced by environmental conditions from development to maturity.
