| 总结: | The growing demand for Stevia rebaudiana Bertoni as a natural sweetener requires the search for more sustainable production systems. Phosphorus is essential in this crop, as it is involved in processes of energy transformation and biosynthesis of phytochemicals; its low availability affects production and retards plant growth. Symbiosis with arbuscular mycorrhizal fungi (AMF) represents a sustainable way to increase crop production, thanks to a better absorption of nutrients, particularly phosphorus. The objective of this study was to evaluate the effect of native AMF consortia, from the locations: Reserva Cuxtal (RC), Tizimín (TZ) and Colonia Yucatán (CY) belonging to the state of Yucatán, with percentages of phosphorus based on to its nutritional requirement, on growth parameters and photosynthesis in S. rebaudiana at the greenhouse level. A completely randomized design with a 4X5 bifactorial arrangement was used. The results indicated that, at low concentrations of phosphorus, there is greater mycorrhizal colonization. The RC+25 % P and CY+25 % P treatments increased growth, improved the aerial architecture of the plants and biomass production, derived from a higher chlorophyll content and a better photosynthetic rate compared to non-inoculated plants. |
