摘要： 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.

摘要： Disclosed are bacteria and methods for promoting growth of Racomitrium canescens, tobacco, barley and soybean. The bacteria are selected from the methanol-utilizing bacteria deposited under Accession numbers FERM BP-11078, FERM BP-11079, FERM BP-11080 and FERM BP-11071, respectively which bacteria belong to the genus Methylobacterium. The methods are a method for promoting growth of protonemata of Racomitrium canescens which method is characterized by culturing the protonemata in the presence of the bacteria and a method for promoting growth of a seed plant selected from the group consisting of tobacco, barley and soybean which method is characterized by culturing seeds of the seed plant while contacting the seeds with the bacterium deposited under Accession number FERM BP-11078 which is one of the above-mentioned bacteria.
