Abstract

Mycorrhizal symbiosis is the result of mutualistic interactions between plants and fungi. Melinjo (Gnetum gnemon) naturally associate with ectomycorrhizal Scleroderma sinnamariense and Scleroderma sp. fungi. Artificial inoculation can be applied to young seedlings (1-2 months old), before the roots contain woody material. The purpose of this study was to apply the root pruning techniques to improve gnetum mycorrhizal seedlings production. The study was conducted in a greenhouse using 7 months old seedlings. The treatments consisted of 3 root pruning levels (0, 30, and 50%) and ectomycorrhizal fungi inoculum (control, mycorrhizal seedlings, and soil inoculum). Observations were carried out for 4 months to the seedling growth and root colonization by ectomycorrhizal fungi. Height, diameter, and biomass of melinjo seedlings in all treatments were not significantly different. Thus, root pruning activities do not affect the growth of seedlings. Artificial inoculation produce mycorrhizal seedlings, whereas controls were uninfected. Root pruning increased number of root branching. Root pruning at level 50% increased mycorrhizal seedlings production, but the percentage of root colonization was not significantly difefernt at all pruning levels.

Abstract

Root pruning technique may improve new lateral growth. The purposes of this research are to analyse the combined effect of root pruning and inoculum ectomycorrizal types on the growth of gnetum seedling (Gnetum gnemon). This research using split plot design. The source of ectomycorrizhal inoculum as main plot consist of 3 types: control, infected seedling of ectomycorrhizal, and soil inoculum. The root pruning level as sub plot also consist of 3 types: 0, 30, and 50%. Observation is conducted on month 5th and 6th after treatment. The result of this research indicates that root pruning technique on 7 month seedling able to enhance melinjo seedling’s growth and increase ectomycorrhizal colonization (Scleroderma spp.) after 6 months observation. The source of inoculum was able to enhance ectomyrorrhizal colonization but had no significant to gnetum seedling’s growth on month 6th after treatment. Interaction between root pruning 30% and fungal inoculation with soil inoculum source can improve gnetum seedling growth.
