Abstract

The purpose of this study was to determine the effects of several organic growth factors on the growth of the potato bud and root. Each potato bud was excised from the tuber in the form of a one inch cube. The cube was actually mostly tuber tissue with the bud on the surface. Each cube was placed in a flask with modified White's growth medium and water soluble vitamins. The flask was capped and the bud allowed to grow for seven days. Careful attention was paid to proper sterilization procedures. The vitamins used were p-aminobenzoic acid, pyridoxine, ascorbic acid, thiamine hydrochloride, niacinamide, riboflavin, and calcium pantothenate. All the vitamins except one were placed in each medium. Thus, seven media were prepared; each one had a different vitamin omitted. An eighth containing all the vitamins was the complete group. After the seven day growth period had elapsed, measurements were taken of the bud growth, the weight of the plug, the number of roots, and the length of the longest root. It was suggested by this study that the omission of p-amino-benzoic acid enhances the increase of total wet weight. Changes in the Bud/Root Ratio in the absence of riboflavin were observed. This indicates the influence of riboflavin on the pattern of growth.
