“…This may be explained by the complementarity of environmental elements (nutrients vs. hydrology). Lower water levels reduce plant above-and below-ground biomass and inhibit plant height, leaf area, and root length (Bai et al, 2021). Declining biomass production and accumulation increase the relative content values of organ nutrients based on a fundamental trade-off in plant functioning between the rapid production of biomass and efficient conservation of nutrients (Garnier et al, 2001).…”

“…Related studies have shown that both N and P fertilizers can contribute to the dominance of G. spiculosa (Mao et al, 2014(Mao et al, , 2016. The responses of biomass allocation and root clonal structures of G. spiculosa under nutrient input and flooding show that it has high plasticity under environmental changes (Luo et al, 2010;Bai et al, 2021). Nevertheless, little is known about the nutrient stoichiometries of roots, stems, and leaf organs of the species, and this limits the understanding of the responses of G. spiculosa and its community succession in different agricultural interventions.…”

“…During the past decades, anthropogenic activities of wetland cultivation have significantly caused over 50% of degradation or loss of wetlands (Zedler and Kercher, 2005), consequently increasing wetland fragmentation and altering the hydrological conditions as well as soil nutrient conditions due to drainage and fertilization (Zedler and Kercher, 2005;Zheng et al, 2017;Qin et al, 2021). Further, these variations in hydrology and soil nutrients have been found to affect plant growth, reproduction, and community structures in wetlands (Li et al, 2018;Bai et al, 2021).…”

“…However, these studies tend to focus on the plant leaf or stem and neglect the belowground plant organs as plant growth and reproduction depend upon the roots to absorb and fix nutrients (Kramer-Walter et al, 2016). Given the tendency of plants to allocate nutrients among different organs to maximize soil nutrient availability (Yu et al, 2015;Di Palo and Fornara, 2017;Bai et al, 2021), the study of plant nutrient stoichiometries above-and below-ground could lead to a better understanding of wetland plant responses to agricultural interventions.…”

“…Glyceria spiculosa (Schmidt) Roshev. (Gramineae) is an emergent macrophyte commonly found in freshwater marshes and is widely distributed in China, East Russia, and North Korea (Bai et al, 2021). Related studies have shown that both N and P fertilizers can contribute to the dominance of G. spiculosa (Mao et al, 2014(Mao et al, , 2016.…”

Plant nutrient stoichiometry indicates the balance of plant internal nutrients and its nutrient-use strategies in response to environmental changes. However, the responses of nutrient stoichiometry in different wetland plant organs under agricultural intervention are poorly understood. Here, we compared the nitrogen (N), phosphorus (P), and the ratio of N:P in the plant organs (leaves, stems, roots, and root hair) of a typical helophyte plant (Glyceria spiculosa) in reference, drained, nutrient-rich, and cultivated wetlands (CW) located downstream of the Tumen River in Northeast China. Compared with that in reference wetlands (RW), the results indicate that the average N content in plant leaves, stems, roots, and root hair in nutrient-rich wetlands (NW) was significantly higher by 76, 61, 56, and 39%, respectively (p < 0.05), whereas the N content of roots and root hair in drained wetlands (DW) was significantly higher by 17 and 32%, respectively (p < 0.05). It was found that plant root P increased only in nutrient-rich and DW (p < 0.05). Interestingly, the agricultural interventions significantly affected soil N and P availability, resulting in positive effects on plant leaves, stems, roots, and root hair. Nutrient stoichiometry analysis showed the highest increase in plant leaf N:P ratio in NW, followed by that in drained and CW, but its ratio in root and root hair showed no significant changes under different agricultural interventions, which suggests that G. spiculosa allocates nutrients differently in different organs under agricultural interventions. These results imply that plant nutrient stoichiometry should incorporate various plant organs for an in-depth understanding of plant strategies against environmental changes.

Early recruitment process dominated by vegetation reproduction for wetland plant is a key life-history stage affecting species distribution. Extreme climatic events, such as extreme temperature and heavy rainfall have been predicted to become more intense and frequent under future climate scenarios. To explore the effect of temperature and ooding depth on tubers sprouting and early growth of Bolboschoenus planiculmis, we conducted two arti cial experiments in the incubator and greenhouse,
