Seedlings: Collection are made under the mother plant when cuttings and seeds are limited. 4.Grafting and Air layering: In rare cases these methods are done directly on the mother plant when plant materials are limited. 5.Tissue culture: This method is done with the help of external laboratories, e.g: Kew Garden and Brest
