不同种植模式下的菌根网络对狼尾草生长与耐碱性的影响
Effects of common mycorrhizal networks on the growth and alkali tolerance of Pennisetum alopecuroides under different planting patterns
土壤丛枝菌根(AM)真菌可以通过公共菌根网络(CMNs)连接不同植物根系介导植物之间养分传递和资源分配影响植物间互作。然而,在土壤盐碱化严重威胁草地生态系统可持续性的背景下,CMNs在碱环境下对供体植物生长和耐碱性的影响仍不明确。本研究以接种AM真菌的狼尾草为供体植物,采用不同的种植模式:分隔网另一侧无相邻受体植物(无邻体植物种植)、相邻受体植物分别为未接菌的狼尾草(同种植物种植)和未接菌的车前(异种植物种植),通过分室盆栽试验,探究碱胁迫下CMNs对供体植物狼尾草的作用。结果表明:1)碱胁迫下邻体植物(尤其同种植物)显著提高了狼尾草的定殖率和定殖强度;2)碱胁迫下接菌处理中邻体植物为同种植物的处理组狼尾草菌根依赖性和易提取球囊霉素相关土壤蛋白(EE-GRSP)含量显著高于无邻体植物处理组和异种邻体植物处理组;3)碱胁迫显著抑制狼尾草生长,CMNs的建立缓解了该胁迫效应;4)碱胁迫下CMNs显著提高狼尾草的光合能力、渗透调节物质及抗氧化酶活性,降低丙二醛和超氧阴离子自由基含量;5)隶属函数分析表明,碱胁迫下接菌处理中邻体植物为同种植物的处理组耐碱性最强。研究表明AM真菌驱动的CMNs可能通过介导植物互作促进供体植物狼尾草生长并增强其耐碱能力,特别是与同种植物形成的CMNs对狼尾草的促进作用更显著。
Arbuscular mycorrhizal (AM) fungi connect the roots of different plants via common mycorrhizal networks (CMNs), mediating nutrient transfer and resource allocation among plants and influencing plant interactions. Soil salinization threatens the sustainability of grassland ecosystems, but the impact of CMNs on donor plant growth and alkali stress tolerance in alkaline environments remains unclear. In this study, Pennisetum alopecuroides inoculated with AM fungi served as the donor plant. Different transplanting patterns were established using compartmentalized pot experiments: no adjacent receiver plant on the other side of the root barrier mesh (neighborless plants), an adjacent uninoculated P. alopecuroides receiver plant (conspecific planting), and an adjacent uninoculated Plantago asiatica receiver plant (heterospecific planting). This experiment was designed to investigate the role of CMNs under alkali stress on the donor plant P. alopecuroides. The results demonstrate that: 1) Under alkali stress, the presence of neighboring plants (particularly conspecific neighbors) significantly increased the mycorrhizal colonization rate and colonization intensity in P. alopecuroides. 2) Under alkali stress and AM inoculation, P. alopecuroides in the conspecific neighbor treatment exhibited significantly higher mycorrhizal dependency and soil easily extractable glomalin-related soil protein content compared with both the neighborless and heterospecific neighbor treatments. 3) Alkali stress significantly inhibited the growth of P. alopecuroides, but the establishment of CMNs alleviated this effect. 4) Under alkali stress, CMNs significantly enhanced the photosynthetic capacity, levels of osmotic adjustment substances, and antioxidant enzyme activities in P. alopecuroides, while reducing malondialdehyde and superoxide anion radical contents. 5) A subordinate function analysis indicated that under alkali stress and AM inoculation, the conspecific neighbor treatment conferred the strongest alkali tolerance upon P. alopecuroides. The results of this study demonstrate that AM fungus-driven CMNs can promote the growth of P. alopecuroides and enhance its alkali tolerance by mediating plant-plant interactions. Notably, CMNs formed with conspecific neighbors had the most pronounced beneficial effect on P. alopecuroides.
