This study focuses on the physical properties of new growth stalk for passion fruits to find out the relationship between force and displacement in the bioyield. Furthermore, by use Instron testing machine to measure the material properties. The results show that the minimum press 0.166N/mm^2 approximately and elastic contact with a spheroid and a base by simulate to calculate forced situation of foreign claw clipping grafted seedlings. The testing results show that the maximum press 8.6Pa of the grafting clip and compress it to 14mm obtained force 6.46N by it opening maximum distance along the slide not to hurt stalk of the passion fruits.
