Abstract
The influence of six boron treatments (0, 0.1, 0.5, 2.5, 5.0 and 10.0 ppm) on glucosinolates and reducing sugars was studied in tops and roots of hydroponically grown Snow Ball turnip (Brassica rapa L.). The glucosinolates were determined by quantifying their hydrolytic products, 5-vinyl-oxazolidine-2-thione (goitrin), volatile isothiocyanates, and thiocyanate ion. While growth of plants receiving no boron (0 ppm) was drastically impaired, that of plants receiving 0.1–5.0 ppm boron was equally vigorous; growth was slightly inhibited with 10.0 ppm boron. Mild boron deficiency was manifested as brown-heart in roots of fully-sized turnips from the 0.1 ppm boron treatment although there was no apparent effect on external root appearance or on foliage and plant growth. In roots of boron-deficient turnips, elevated yields of goitrin were found, accompanied by relatively high yields of thiocyanate ion and low contents of reducing sugars.
