Research Abstract

Seedless expression derived from 'Mukaku Kishu' is not directly related with plan growth substances. A mechanism of seedless expression derived from 'Mukaku Kishu' is released by high temperature and the seeds are developed. It is suggested that the high temperature during 0 to 4 weeks after flowering would be related with a release of the seedless expression mechanisms.
