The results indicated as pH values in the range from 4.50 to 7.50, the volume and dry weight of root increased as pH values increased, as well as AAAR,TAAR. The relationship of nicotine and total nitrogen accumulation with pH values was parabola,the functions were Y=-61.429X2+391.17X-162.8 (F=l 8.45), Y=-24.3X2+154.88X+52.7 (F=14.40**) respectively. When pH value got rise to 7.50, the accumulation of nicotine and total nitrogen attained the highest .
