“…Alginates from seaweed extracts promote the growth of beneficial fungi, significantly increase hyphal growth, and increase the length of roots [75]. As with our findings, previous studies have documented the positive impact of AMF and SWE co-application on the N, K, P, and other micronutrients content of several plant species, including garlic (Allium sativum) [76], date palm (Phoenix dactylifera) [26], and Pinus greggii [77]. SWE fertilizer provides the crop with a complete range of macronutrients and micronutrients, such as polysaccharides, amino acids, vitamins, and other active substances, which help the plant to build a strong root system, but also improve the uptake of the nutrients, water and gases [78], as we showed also in our experiment.…”

Beneficial plant–microbe interaction for enhancing crop yield and quality is a sustainable way to achieve eco-friendly, desirable agricultural productions. The main objective of this experiment was to evaluate the individual and combined effects of an arbuscular mycorrhizal fungus (AMF) strain (Funneliformis mosseae) and a seaweed extract (SWE) derived from Ascophyllum nodosum, on the growth and physiological responses of lettuce (Lactuca sativa L.). Lettuce plants were inoculated with commercial AMF inoculum (5 g kg−1 soil), and SWE foliar application was done at three levels (0.5, 1.5, and 3 g L−1). The findings revealed that AMF along with SWE generated the greatest impact. In fact, co-application of AMF inoculation and 3 g L−1 SWE considerably enhanced root colonization, chlorophyll a, chlorophyll b, total chlorophyll, carotenoids, and mineral content in the shoots and roots (N, P, K, Ca, Fe, Zn, and Mn content) of lettuce plants. This combination improved initial fluorescence (F0), photochemical efficiency of PSII (FV/Fm) and Y(NO) and total antioxidant activity (TAA), whereas the maximum fluorescence, (Fm) and Y(II), showed the highest increase in lettuce plants treated with AMF and 1.5 g L−1 SWE. Furthermore, AMF inoculation along with SWE, at concentrations 1.5 and 3 g L−1, considerably enhanced variable fluorescence (FV) and the activity of water decomposition in electron donor photosystem II (FV/F0). As a result of these findings, it can be stated that the co-application of AMF and SWE positively improves the growth and development of lettuce plants.

“…Franco) seedlings showed no difference in biomass with AM colonization (Smith et al 1998), and Arizona longleaf pine (Pinus engelmannii Carrière) and Gregg's pine (Pinus greggii Engelm.) showed positive growth responses to AM inoculation (Montes-Rivera et al 2001;Franco-Ramírez et al 2021). Therefore, the overall effects of AM fungal interactions with members of the Pinaceae are context dependent and not fully understood.…”

Effects of dual mycorrhizal inoculation on Pinus strobus seedlings are influenced by soil resource availability

Mycorrhizal interactions can drive plant productivity, diversity, and ecosystem function; however, gaps remain in our understanding of interactions among plants and different mycorrhizal types. Species in the Pinaceae primarily associate with ectomycorrhizal (ECM) fungi; however, some species can be colonized by arbuscular mycorrhizal (AM) fungi as rudimentary hosts. Interactions between plants and mycorrhizal fungi are expected to change along the mutualism-parasitism spectrum with changes in resource availability; however, the impacts of AM fungi on rudimentary hosts under different resource conditions are unknown. METHODSIn this study, we assessed the individual and interactive effects of ECM and AM inoculation on Pinus strobus seedlings under factorial combinations of low, medium, or high nitrogen (N) and phosphorus (P) supply. RESULTSNo AM colonization was observed at the end of the experiment; however, seedlings inoculated with AM fungi showed signi cantly reduced growth. AM inoculation also had the greatest effect on P. strobus tissue nutrient concentrations under low N fertilization including increased P and reduced Mn and N:P ratio. ECM colonization bene ted P. strobus growth and P uptake, especially under low P availability, but ECM colonization rate itself was limited by low P. ECM colonization also improved seedling regulation of N:P ratio near optimum compared to uncolonized seedlings. CONCLUSIONWe conclude that the effects of ECM and AM inoculation on P. strobus are context dependent, which may have important implications for regeneration and early growth of P. strobus in natural and managed forests.
