| Outline of Final Research Achievements |
The final objective of this research is to establish a growth control method to produce high quality saffron. Growth phase of saffron is induced by air temperature. It would be possible for far-red light to improve translocation of carbon assimilation products and to encourage the development of daughter corm. Therefore, the effects of air temperature and far-red light on the development of daughter corm and crocin content in stigmas were clarified.
In order to harvest high quality stigmas, it is necessary to select superior corms, which contain a lot of starch. A non-destructive method to measure the starch content in a corm was developed by an analysis of light scattering image of saffron surface. Though the estimation accuracy of calibration model was not sufficient for practical use, technical problems that should be solved were clarified. It is predicted that the estimation accuracy can be improved and this method would be turned into actual utilization in the future.
