Effects of Phytohormones and Light on Polyamine Content and Arginine Decarboxylace Activity in Ginseng

식물호르몬과 광이 인삼의 Polyamine 함량과 Arginine decarboxylase 활성도에 미치는 영향

The effect of some phytohormones and light on the growth, ADC activity and polyamine content in ginseng was studies. In seedlings, the growth, ADC activity and putrescine content were in creased by Ghs treatment. ADC activity ann putrescine content were slightly slightly derreased by ABA, but not changed by kinetin. Light treatment increased ADC activity and putrescine content greatly. In two year ginseng leaves treated by GA3, the ADC actin$.$its reached maximum and the spermidine content reached maximum 2 days faster than in the control. Thtse results suggest the possibility that these regulators are closely related to growth and polyamine cotent. UeVo'ordsEPanaxgineng C.A.
