供試材料為日本種三島柴胡，以缽栽及田問試驗同時進行，生長調節劑以CCC及SADH各分為3,000, 5,000, 7,000 ppm 單寧酸（TA）分為500, l,000, l,500 ppm 和對照區（摘心）等10處理。以探究該等生長調節劑對抑制柴胡植株地上部生長，促進主根之肥大，減少不定根的發生之效果；藉以提高柴胡根收量及品質。茲將研究結果摘述如下：
缽栽試臉部份：1. 鮮很收量以CCC 5,000 ppm 處理為佳，比對照（摘心）處理可增加1g/plant，亦即可0提高收量14%；但不定根發生多，品質劣化。SADH各種濃度處理對根產量有降低之趨勢，但在Saponin方面，濃度愈低則Saponin 含量愈高。2. 單寧酸濃度高（1,500 ppm ) 時不定根發生少，且可抑制不定很的發生，但收量有減收的傾向；單寧酸濃度低（500 ppm）時對Saponin含量有提高之趨勢，比對照（摘心）處理可增加1.1%。
田間試瞼部份：1. SADH 5,000 ppm濃度處理時對品質及Saponin含量均有提高之趨勢，其Saponin較對照 （摘心）處理可增加2.3%，但收量較低。而在不司CCC濃度處理下對品質、Saponin含量及收量較無效果。 2. 單寧酸濃度低（500 ppm）時，對Saponin含量，色澤，收量均可增大，但不定根較多且無柔軟性；單寧酸濃度高（1,500 ppm）則對品質及Saponin含量有益，但收量較低。
This study was to investigate the inhibitory effects of plant growth regulators on the overgrowth and the occurrence of adventitious roots in Bupleurum falcatum L. plants, in order to improve the yield and quality through promoting the growth of main root. A japanese variety, San-two, was selected for experiments. CCC (2-chioroethyltri methylammonium chloride) and SADH (Succinic acid 2, 2-dimethyl hydrazide) each at concentrations of 3,000, 5,000 and 7,000ppm, and TA (tannic acid) at concentrations of 500, 1,000 and 1, 500ppm were foliar-applied separately four times in both the pot and field experiments with topping as the check treatment.
In pot experiment, CCC (5,000 ppm) increased root yield by 14% but lowered saponin content and produced more adventitious roots. A significant decrease in root production was observed in SADH treatments, however, saponin content was increased when the concentrations were low (3,000 and 5,000 ppm). The application of TA also tended to decreased root yield and saponin content 1.1% higher than the check treatment was recorded at the concentration of 500 ppm.
Compared with topping, all the treatments gave a lower number of adventitious root but also a lower yield per plant in field experiment. on the contrary, saponin concentration was significantly higher in most treatments. Experimental results showed that root yield was correlated positively (at 1% level) with plant height and diameter and length of roots but negatively (at 5% level) with tiller number. Saponin concentration was negatively correlated with plant height, root diameter and yield at significant levels.
