Growth enhancement of the highly prized tropical trees siamese rosewood and burma padauk

Enhancement of growth and Cannabinoids content of hemp (Cannabis sativa) using arbuscular mycorrhizal fungi

“…According to our previous studies, both AMF species showed high efficiency in enhancing plant growth and biomass in two woody legumes (Siamese rosewood and Burma padauk; Seemakram et al, 2021) and plant secondary metabolites in Jerusalem artichoke (Nacoon et al, 2021). Therefore, inoculation of these species was expected to play an important role in improving growth and production of secondary metabolites in cannabis.…”

“…Maize was grown in a greenhouse at 30–35°C with daily irrigation using tap water. After 90 days, irrigation was stopped in order to allow the plants to dry for 5 days, by which spore formation of AMF was induced ( Seemakram et al, 2021 ). Plants were subsequently cut off just above the soil surface.…”

“…In order to reduce the use of synthetic fertilizers to promote the growth and yield of cannabis, plant growth promoting microorganisms (PGPM) are of interest and they have been extensively studied due to their environmentallyfriendly nature (Andre et al, 2016;Pagnani et al, 2018). Arbuscular mycorrhizal fungi (AMF) are a group of fungi belonging to the subphylum Glomeromycotina, phylum Mucoromycota (Spatafora et al, 2016) that live in a mutualistic symbiosis with plant roots of the majority (>80%) of terrestrial plant species (Boonlue et al, 2012;Seemakram et al, 2021). AMF develop extraradical mycelia that extend the depletion zone that develops around roots, and facilitate the acquisition of nutrients of low mobility.…”

“…Smith) C. Walker BM-3 g3 and Rhizophagus prolifer (Dalpé & Declerck) C. Walker & Schluessler PC2-2 were investigated in a pot trial for their efficiency to promote growth and yield of cannabinoids. Both AMF species promoted growth in the legume family [Siamese rosewood ( Dalbergia cochinchinensis ) and Burma padauk ( Pterocarpus macrocarpus )] and the production of plant secondary metabolites in Jerusalem artichoke ( Helianthus tuberosus ) plants ( Nacoon et al, 2021 ; Seemakram et al, 2021 ). However, there is still no report investigating the effects of both AMF species on the growth and production of secondary metabolites of cannabis.…”
