Severance of arbuscular mycorrhizal fungal mycelial networks in restoration grasslands enhances seedling biomass

“…Our results are contrasting with several other studies where exposure to AMF hyphal networks was documented to enhance seedling growth (Weremijewicz & Janos, 2013;Liu et al, 2014; Ó 2021 The Authors New Phytologist Ó 2021 New Phytologist Foundation New Phytologist (2021) www.newphytologist.com Wang et al, 2020). In those studies, however, all plants were of similar age, whereas in our field experiment most surrounding plants were well established.…”

Divergence in Corn Mycorrhizal Colonization Patterns Due to Organic Treatment

“…Mycorrhizal communities produce various plant benefits; these led to a positive effect on plant biomass, but also on P content of maize. A reduction in colonization was observed in plants to which P fertilizers were applied, showing that colonized plants can acquire essential nutrients and thus save P-based fertilizer, especially in fields where it has been previously applied [39]. Low concentrations of fertilizers with N and P do not significantly affect the development of colonization, but an increase in nutrient concentration acts as a restrictor for this mechanism.…”

Arbuscular mycorrhizal symbiosis increases phosphorus uptake and productivity of mixtures of maize varieties compared to monocultures

“…Moreover, another reason we selected these varieties was that they represented landrace (HMY), hybrid (ZD2) and inbred line (197) respectively. We have also executed earlier studies on genetic variation in mycorrhizal response of maize landraces, inbred lines and hybrids (Wang, van der Werf, et al, 2020). In 2013, we tested one additional maize variety, Xianyu 335 (XY335), a newly released and widely grown maize variety, which can take up P from phytate via mycorrhizal hyphae (Wang et al., 2017).…”
