Method of producing potato microtuber of high quality by optimizing light culture

摘要

A method to increase the productivity of microtuber potato seeds that can be directly seeded is presented. According to the method of the present invention, the amount of light at the time of tissue culture of potato stems is 130 to 180 umol/m ² /sec, the ammonium nitrate content is 800 to 1200 mg/L and the potassium nitrate content is 3000 to 4000 based on the composition of the MS medium. By culturing in a medium condition adjusted to mg/L, it is possible to improve the growth of potato plants and finally produce large amounts of microtuber potato seeds having a large size.
