This invention relates to a process for producing stigma-like tissues of saffron in a large scale by cutting the tissues of stigma (c), style (d, e, f), ovary (h, i, k), ovule (j), and petal (r) of saffron flower, and subculturing them on a liquid or solid LS medium or B5 medium containing a cytokinin and an auxin as main hormones.

Process for culturing saffron stigma tissues

A tremolo device for a guitar which includes a flat plate pivotably mounted about a fulcrum on a guitar body, a bar secured to the flat plate to receive and anchor strings of the guitar, at least one tension spring for exerting pressure against the flat plate and the bar in one rotating direction, against the tension of the guitar strings, a tremolo arm screwed into the flat plate to oscillate the flat plate and the bar to thereby produce a tremolo effect, a stabilizing plate provided on the bar to stabilize the initial position of the flat plate and the bar, and an abutting mechanism provided on the guitar body to support the flat plate and the bar through the stabilizing plate. The stabilizing plate has a dead point on the periphery thereof, and when the abutting mechanism comes into contact with that dead point, the flat plate and the bar can be most stably supported by the abutting mechanism.
