Research Abstract	Availability of short pruning system for mango production with heated-greenhouse in Japanese warm temperate zone, with short bearing shoots replaced every year on opposed two main stems, was studied. Lateral current shoots developed directly on main stems were used for fruit production. After the harvest, they were cut near the base with 2 or 3 lateral buds to form new productive shoots for next season; renewal productive shoots for next season can be got easily. Enough number of inflorescence for fruit production was got on the short pruning trees. Additional studies about the usage of parthenocarpic fruit formed in an insulated greenhouse at a flowering were also conducted. The application of gibberellin for stimulation of seedless fruit growth is a possible method to resolve this problem.
