川芎喷施青霉素研究初报

Preliminary Study on Spraying Penicillin on Ljgusticum chuanxiong Hort.

川芎喷施青霉素后，降低了植物组织水势，增强了吸水能力；提高了叶绿素含量并抑制其降解，有利于光合产物的形成；增加了营养根，提高了根冠比值，经济产量得到了较大提高；控制川芎根腐病发病在５％以下。

t has been proved that penicillin spray on Ligusticum chuanxiong can contribute to the growth of the plant inthe following ways:cutting down the tissue water potential,strengtkening the capability of sucking moisture,in-creasing the contents of chlorophyll and restraining its degradation to facilitate the formation of photosyntheticcompounds,enriching the nutrition root and increasing the root-shoot ratio. All these help to keep the stem tuber-ot under 5%so as to guarantee higher economic yield of the plant.
