為探討摘心與MH(Maleic hydrazide）處理對於柴胡根產量及品質之影響，舉行本試驗，自1974年8月至1975年7月止。供試材料為日本型柴胡，分七個不同摘心與MH葉面撒布處理。試驗結果摘述如下：1. 摘心對地下部的不定根發生多，品質劣化，但收量增加2.99/plant（表1）。2. MH處理者根收量減少，但MH撒布後可抑制不定根的發生，故品質較好，其中以撒布5,000ppm濃度時，品質為最佳。3. 摘心可提高根中的Saponin含量（表1）。MH處理則相反，其含量有降低之趨勢。
The objectives of this experiment were to find out the effects of topping and MH (maleic hydrazide) application on the quality and root yield of a medicinal plant, Bupleurum falcatum L. The experiment was conducted at Tahshue mountain during the period of August 1974-July 1975. A Japanese variety of Bupleurum falcatum was foliar sprayed with five levels of MH plus topping and no topping treatments.
1. It was observed that the topping treatment resulted in an increase of the indefinite roots which reduced the root quality. Nevertheless, the leaf topping caused to increase the root yield at a level of 2.9 g per plant.
2. Although MH spray resulted in a reduction of root yield, however the root quality became better due to a reduction of the nember of indefinite root. The root quality was found to be the best at 5000ppm of MH concentration.
3. The root saponin content was found to be higher in topping treatment but lower in the MH foliar sprayed plots.
