Their in vitro clonal propagation would assist forest tree improvement and silvacultural research. The research efforts in clonal propagation of these three genera are reviewed with respect to plant growth regulator effects as they are related to primary explant source, multiple shoot formation, somatic embryogenesis, rooting, and transfer to soil.</style></abstract><issue><style face="normal" font="default" size="100%">28</style></issue></record></records></xml>
