- Toyoshi mouth, make-in and russet 'microphone using Russet Burbank The effects of 2-chloroethylphosphonic acid and ethylene inlet on the mouth tube were investigated.
- Toyoshi mouth and make-in make three bottles of seedlings per bottle, and Russet 'Nokuichi Bank uses 2 * "f two bottles of seedlings (both bottle seedlings are both Japanese tobacco ⁇ ⁇ ⁇
- the culture was separated from the seedlings that had been difficult to preserve, and the culture was released under the same conditions as in starvation example 1 except that the culture medium was set to 500 ml.
- Ethylene is cultured from the 2nd and 4th week. From the 2nd week and the 4th week, a 2-L container separate from the culture container containing 500 ml of commercially available 2-chloroethylphosphonic acid (1,000 times) ⁇ ]. The pH of the 2-chloroethylphosphonic acid solution was adjusted to about 5.5 after dilution to promote 3 ⁇ 4 ⁇ of ethylene from 2-chloroethylphosphonic acid. The aeration of ⁇ containing 2-chloroethylphosphonic acid went into the sickle. In this case, ventilation was performed through this cell until culture. On the 35th day of culture, the medium was turned into female medium, and the microtuber was harvested on the 35th day.
- the method of this translation can save a lot of micro-chus in a forehead and a short time compared to the method of the thread. Also, the obtained microtube is large in size and excellent in rawness. Therefore, the present invention is not a leak. ⁇ brief description
