| Outline of Final Research Achievements |
I could not transfer BrdU from a bottom of stem to accessory bud, which developed to aerial tuber, for calculate the division frequency. However, I could get various result about the relationship shoot and new tuber growth, which influenced the aerial tuber growth. Regression equation got from leaves dry weight to stem dry weight and from shoot dry weight to leaves dry weight were high coefficient of determination. It was cleared that shoot and new tuber growth was promoted or inhibited by amount of irrigation at each different growth stage. Further, dry weight distribution to each organ was influenced by different method fertilization. Namely, in case of lack of fertilizer, there were a lot of the distribution of dried photosynthate weight to new tuber were increasing, while, in case of sufficiently of fertilizer, there were a lot of the distribution of dried them weight were increasing. I will kept studying about aerial tuber development using above result in future.
