Abstract: An efficient micropropagation protocol for large scale production of hazelnut plants is required for consistent supply of elite germplasm to support the growing industry in Ontario. The main focus of current research was to develop a bioreactor based micropropagation protocol for hazelnut multiplication. An integrated approach was developed to increase the multiplication rate by optimizing the nutrient medium supplements and culture technology using a temporary immersion bioreactor system (TIS). As compared to conventional semi-solid and liquid based culture system, the Liquid LabTM temporary immersion bioreactor system (LIS) showed a significant enhancement in the number of shoots (3.3 shoots/explant), shoot height, leaf area and chlorophyll content in micropropagated plantlets. Antioxidant supplements such as ascorbic acid and melatonin along with iron (460 µM FeEDDHA) significantly increased the shoot proliferation (5.5 shoots/explant). However, a much higher shoot proliferation (10.9 shoots/explant) was observed with the addition of aspirin (10 µM) in the presence of BA (17.6 µM). Among several hazelnut cultivars, HF-16 had the highest multiplication rate followed by Geneva and Epsilon. Medium supplemented with 10 µM IBA was the best for rooting of microshoots of HF-16 and the plantlets acclimatized in the green house with 80% survival rate.
