Abstract
This study was carried out at tissue culture laborotaries of ornamental plants and woody trees department and Plant biotechnology department, National Research Center (NRC) Egypt during years 2013 and 2018 to establish an in vitro protocol for micropropagation of Khaya senegalensis from seed plants and The effect of various concentrations of BA and different types of culture media at two strengths (Full and half strengths) for three repeated subcultures on Khaya shootlets proliferation was studied. For rooting stage, shootlet were precultured on different concentration of IBA for one week and incubated for one week under dark conditions. Also to establish a protocol for micropropagation of Neem tree using direct organogenesis from nodal explants and Neem tree through somatic embryogenesis from in vitro leaves (indirect) and effect of JA on growth as fresh and dry weight on callus and embryos of neem
