Stimulation Effect of a Soft Ferrite Ceramic Powder on Growth in Plant Cell and Tissue Cultures

연자성 세라믹 분말에 의한 식물세포 및 조직의 생장촉진 효과

The addition of the ceramic powder as state of bare in culture medium has stimulated the growth of Achyranthes japonica in both the disorganized cell and the plantlet. The grwoth rate of Hyoscyamus niger adventitious root and Pylatycodon grandiflorum hairy root was enhanced up to 100 and 250%, respectively, even though Scopolia parviflora hairy root and Hyoscyamus albus adventitious root were not. The ceramic powder has enhanced the growth of H. niger adventitious root even in a test tube immersed into its culture medium to irradiate alone without any direct contact. The ceramic powder seems to have a significant role on both the growth and the physiological action of some plants.
