Outline of Final Research Achievements

The relationship between the shoot and root of root crop was investigated. This was performed through tracing the growth of each part. The parameters observed for the shoot were the percentage of the vegetation cover, chlorophyll concentration, and the yield of the photosynthesis. On the other hand, the diameter and the sugar concentration were the two parameters estimated for observing the root. The root diameter was estimated using a special device developed earlier to estimate the growth and fleshiness. Although the vegetation cover reached saturation by the end of July, the fleshiness of the root remained enlarging. It was found that amount of sugar estimated using the root parameters increased proportionally with the amount of photosynthesis estimated using the shoot parameters. Consequently, it could be concluded that there is possibility to estimate the amount of sugar in the root of crop using information obtained from the shoot parameters.
