Emergence and growth performance of Bolboschoenus planiculmis varied in response to water level and soil planting depth: Implications for wetland restoration using tuber transplantation

Morphological and Physiological Traits Related to the Response and Adaption of Bolboschoenus planiculmis Seedlings Grown Under Salt-Alkaline Stress Conditions

“…Thirty fully developed tubers of B. planiculmis of uniform size (mean dry weight 1.2 g) were selected and planted into the soil (5 cm). The pots were watered with a saline-alkaline solution to 50% soil water content to avoid inhibition of root tuber emergence and seedling growth of B. planiculmis due to flooding ( An et al, 2018 ). All the pots were then placed into the growth chambers with a 12-h photoperiod (500 μmol m –2 s –1 of photosynthetically active radiation), 25/20°C day/night temperature, and 70–75% relative humidity.…”

“…Bolboschoenus planiculmis is often found in the saline-sodic wetlands on the western Songnen Plain, where it mainly reproduces and expands its population using vegetative propagules ( An et al, 2018 ). The B. planiculmis wetlands on the Songnen Plain can provide a habitat for the migratory Siberian crane ( Grus leucogeranus ), and the root tubers of this plant are a food source for this waterfowl.…”

“…The B. planiculmis wetlands on the Songnen Plain can provide a habitat for the migratory Siberian crane ( Grus leucogeranus ), and the root tubers of this plant are a food source for this waterfowl. However, these wetlands are suffering from increased soil salinization and alkalinization, and the vegetation is being degraded ( An et al, 2018 ). Existing studies on the growth of B. planiculmis in this area under salt stress have, to our knowledge, only investigated either NaCl or water management ( Zhang et al, 2014 ; An et al, 2018 ).…”

Studies of the effects of saline-sodic stress on B. planiculmis are still lacking, greatly hindering our understanding of this species’ ecological limits.…”

Disentangling Responses of the Subsurface Microbiome to Wetland Status and Implications for Indicating Ecosystem Functions

“…In recent years, the presence of Carex tussock and Phragmites in the marsh have declined dramatically and disappeared in some parts of Northeast China due to land drainage and the intensification of agriculture [14,15]. To cope with this problem, wetland management departments in China have recently attempted to implement wetland restoration practices by restoring the artificial vegetation and effecting reconstruction by introducing the natural vegetation for recolonization after the recovery of hydrological conditions [14,16,17]. The restoration of wetlands is a promising strategy for reestablishing the ecological structure, function, and biodiversity of the aboveground part of degraded wetlands [17,18].…”
