Summary
This study investigates the role of arbuscular mycorrhizal fungi in supporting the acclimatization of tissue-culture-derived Agave marmorata plantlets, a species of arid-zone economic and ecological importance. The findings suggest that AMF inoculation can enhance nutrient uptake — particularly phosphorus — and improve survival and morphological development during the critical transition from in vitro to ex vitro conditions. The research contributes to optimising micropropagation protocols for agave, which is relevant to both commercial production and conservation of arid-land species.
UK applicability
This study is directly applicable to UK conditions only in a limited sense, as Agave marmorata is not a UK crop; however, the underpinning findings on AMF-assisted acclimatization of micropropagated plantlets are broadly relevant to UK protected horticulture and nursery propagation systems where mycorrhizal inoculants are increasingly considered as biostimulants.
Key measures
Plant survival rate (%); shoot height (cm); root length (cm); leaf number; nutrient concentration (N, P, K; mg/kg or %); mycorrhizal colonisation rate (%)
Outcomes reported
The study measured the effects of arbuscular mycorrhizal fungi (AMF) inoculation on growth parameters, nutrient uptake, and survival rates of micropropagated Agave marmorata plantlets during the acclimatization phase. It likely reports improvements in shoot and root development, phosphorus and nitrogen acquisition, and overall plantlet establishment compared to non-inoculated controls.
