ABSTRACT:
The present invention relates to a method of obtaining, on a large scale by tissue culture, tuber of potato, corm of taro, konjak, jack-in-the-culprit, rhizome of Scopolia japonica, tuberous root of Chinese yam, etc. having an enough large size to cultivate seed tubers by one cultivation in the soil. This method comprises culturing the plant itself or its slices in a liquid medium till the plant grows to a size of 15 to 30 cm on the average, sinking 90% or more of the plant in the liquid medium, while further performing cultivation, reducing the amount of the liquid medium with passage of time to such a degree that 50 to 98% of the plant is exposed into the aerial phase to thereby obtain a large amount of tuber, corm, rhizome or tuberous root in a short time.
