Abstract
Regrowth of encapsulated microshoots, using alginate encapsulation, of Cineraria maritima reached 82.35% following 6 months of storage. Amongst developing plantlets, 33.33% exhibited formation of multiple shoots at the onset of regrowth and 11.76% demonstrated simultaneous formation of shoots and roots. Healthy root formation was observed in plantlets following 2 weeks of their transfer to half-strength Murashige and Skoog medium containing 1.0 mg l−1 α-naphthalene acetic acid. Plants were transplanted to the greenhouse in three batches with 90% frequency of survival. Molecular analysis of randomly selected plants from each batch was conducted using 20 random amplified polymorphic DNA (RAPD) markers. Of 20 primers tested, 14 produced amplification products, and a total of 69 bands with an average of 4.93 bands per primer were observed. Of these 69 scorable bands, only 20% of bands were polymorphic. Cluster analysis of the RAPD profiles revealed an average similarity coefficient of 0.944 thus confirming molecular stability of plants derived from encapsulated microshoots following 6 months of storage.
