Micropropagation of Miq and Comparative Antioxidant Properties of Ethanolic Extracts of the Field-Grown Plant, In Vitro Propagated and In Vitro-Derived Callus.

In this study, an efficient micropropagation protocol was developed for and the antioxidant properties of field-grown plant, in vitroderived greenhouse-grown plant and in vitro-derived callus extracts were compared. The seeds tested using tetrazolium chloride salt exhibited 89% viability. Due to poor germination capacity of seeds, the seeds were treated with gibberellic acid (GA) or sulfuric acid (HSO).

Biochemical analyses of Sabin Blue PLBs during cryopreservation by vitrification.

Sabin Blue is an important orchid hybrid that has been grown extensively as cut flower, potted plant and is also popular for its deep purplish blue flowers.  The most efficient long term conservation method of this hybrid is through cryopreservation. Cryopreservation involving the vitrification method consists of explants exposure to highly concentrated cryoprotective solution followed by freezing rapidly in liquid nitrogen.
