Automation of Transplanting

Diagnosis of recovery of roots from transplanting damage

Abstract

In recent years, the need for the greenery, such as flowers and green plants, in the office or home has been increasing. The need for hydroculture has also been increasing because of the aesthetic and sanitary aspects. When a plant is transplanted from soil culture to hydroculture, the roots are damaged. If the plant is sent as a product before recovering from the damage, the plant may not survive. The plants should be cured under a protected environment until the plant has recovered from the transplanting damage. From the viewpoint of cost, the curing time should be as short as possible. The main goal of this study was to develop a method to diagnose when the root sufficiently recovered from the transplanting damage. The light intensity was varied and resulting plant responses, such as changes in diameter and vapor transpiration, were measured. Cross-correlation function were calculated, and showed the significant differences between the plants during the recovery.
