A general introduction of propagation and micropropagation techniques of Macadamia Nut (Macadamia spp.)

Macadamia is categorized into a group of minor crop but can exhibit wide climatic adaptability. It has quick expanding industry demands for its high economic and nutritional values. Graftings, cuttings and micropropagations are the three major propagation methods of macadamia that can be utilized in a combination manner as seedlings with successful graftage can be encouraged to elongate and provide more scion woods for further multiplication such as supporting materials for cuttings. Cuttings can be sprouted to provide explant materials for micropropagation. Therefore, micropropagations are being used for commercial production of macadamia. Micropropagations are comparatively easy and convenient methods that can faster the introduction of any novel varieties into a new region, production of biotic stress tolerant plants, production of plants with greater uniformity and superior branching. Hence, this crop plant might hold an example for the other plants in the next few decades regarding much better application of advance propagation technologies and other genomic approaches.
