| Outline of Final Research Achievements |
Because the concentrations of plant hormones, IAA, iP, Z, the GA4 were highly, it was suggested to syntheses those plant hormones in the seeds. Because the endogenious concentration of Z was higher around 10 times than that of iP, it was discovered that the main cytokinine was Z.
The concentrations of intracellular solution (symplast) was a low value than a cell external solution (apoplast) in all plant hormones 150 days after full bloom. However, apoplastic concentration changed to a higher concentrations than symplast in all plant hormones 177 days after full bloom.
