Genetic Transformation of Orchid Dendrobium Sonia-17 Using the Biolistic Method

The ever-changing tastes and preferences of orchid consumers initiated the need to create new and better varieties. Progress in molecular biology has allowed genetically well defined characteristics to be added to the gene pools, thereby increasing the potential for genetic improvement. However,...
