“…Studies have shown that the application of inorganic fertilizer significantly reduced AMF α-diversity, which showed similar levels to control samples after organic fertilizer [38]. In long-term field experiments, organic and inorganic fertilizers increased and decreased the development of AMF, respectively [39].…”

Heavy metal-polluted soil was collected from the Pulang copper mine in Shangri-La City, Yunnan Province, Southwest China. The effects of fertilizer (organic and inorganic) and arbuscular mycorrhizal fungi (AMF) on ryegrass (Lolium multiflorum L.) growth, root morphology, mineral nutrition and cadmium (Cd) and lead (Pb) contents were investigated by pot experiments. The results showed that both fertilizer and AMF significantly ameliorated the root morphology and mineral nutrition, reduced the Cd and Pb contents, and promoted the growth of ryegrass. Among all treatments, the combined application of organic-inorganic compound fertilizer with AMF had the highest effect, resulting in increases in root length, surface area and branch number by 2.3, 1.1, and 3.9 times, respectively; an 88% increase in plant biomass; a nitrogen content increase of 2.3 and 1.2 times, and phosphorus content increase of 62% and 68% in shoots and roots, respectively was also recorded as well as decreases in Cd content by 34% and 62% and Pb content by 47% and 34% in shoots and roots, respectively. Twofactor analysis showed that both fertilizer and AMF significantly promoted ryegrass growth (plant height, biomass, chlorophyll content, root length, nitrogen and phosphorus content) and reduced the Cd and Pb contents in roots, and there was a synergistic effect between them. Moreover, the nitrogen and phosphorus contents were very significantly positively correlated with the shoot and root biomasses but very significantly negatively correlated with the Cd and Pb contents of ryegrass. Thus, the application of fertilizer and AMF synergistically improved ryegrass growth on polluted soils in the copper mining area.

“…For species with a short lifespan, flowering is quick and the investment in terms of energy in the reproductive organs is high (Newell & Tramer 1978). Thus, species grown in low-fertility soil, besides obtaining benefits from AMF, may also have a stimulated photosynthetic rate (Yolanda et al 2012) that allows better allocation of photoassimilates and nutrients for producing flowers (Stanley et al 1993).…”

Abstract:Arbuscular mycorrhizal fungi (AMF) are an important biotic factor that influences tropical ecological succession and differently affect the woody species belonging to different successional stages. However, little is known about the influence of AMF on growth and reproduction of herbaceous and shrubby species of early phases of tropical succession. Thus, we assessed the effect of AMF on the development of 27 heliophilous herbaceous and shrubby tropical species. Plants were grown in greenhouse, in low- and high-fertility soils, with or without AMF, for 100 d. Most species grown with AMF exhibited high root infection intensity (≈80%), irrespective of soil fertility. In the low-fertility soil, non-mycorrhizal plants exhibited about 88% less shoot dry mass (SDM) than mycorrhizal plants, and AMF were crucial for the survival of most species. Non-mycorrhizal plants also had lower relative growth rate (RGR), total leaf area (TLA), leaf area expansion (LAE) and total root length (TRL). Six species flowered in the low-fertility soil, and flowering increased with AMF in one plant species and four species only flowered when mycorrhizal. In the high-fertility soil, non-mycorrhizal plants exhibited about 13% less SDM than mycorrhizal plants and also exhibited lower TLA, LAE, and nutrient concentrations in shoots. On the other hand, no major changes were observed for RGR, TRL and root dry mass for most of the species. Sixteen plant species flowered in the high-fertility soil, but most had earlier (11) and more abundant (10) flowering when mycorrhizal. Thus, AMF have different influences on the survival, growth and flowering of herbaceous and shrubby tropical species, depending on soil fertility: in low-fertility soil, AMF especially affect the survival, growth and flowering, whereas in high-fertility soil, AMF mainly influence the shoot nutrient concentrations and flowering.
