The purpose of this study was the elucidation of the growth characteristics of the potato. We simultaneously measured changes in stem diameter and growth of potato tuber.
We improved the old equipment that measures the perimeter of the tuber with the new equipment. A potentiometer was used to measure the changes in the diameter of the stem.
We continuously measured the relationship based on enlargement time, period, rate and volume of potato tuber and stem diameter change (information on the ground) by this system.
