چکیده

The synthetic seed technology is becoming popular due to its wide application in germplasm conservation and for exchanges between countries in the floriculture trade. In this study, this method was used to study the germination and conversion capabilities of orchid species Dendrobium White Fairy when stored at different storage times and with different storage containers. A high germination percentage of 80% was observed for encapsulated synthetic seeds up to 150 days of storage in Petri dishes and screw capped polypropylene tubes and this percentage only began to decline gradually from 150 storage days and more. Besides that, synthetic seeds stored in polypropylene tubes were shown to germinate faster and develop into plantlets with longer shoots and roots as compared to those stored in the Petri dishes. This proved the efficiency and suitability of polypropylene tubes over Petri dishes as storage containers.
