Transcriptome analysis of cucumber roots

Here we synthesized and characterized MgFe-layered double hydroxide nanoparticles (MgFe-LDHs), and demonstrated at 1-10 mg/L improved cucumber seed germination and water uptake, with 10 mg/L optimally enhancing emergence and seedling growth under cold stress via root application. Irrigation with 10 mg/L MgFe-LDHs(LDH) at sowing enhanced root length by 12.5%, lateral root number by 45%, root fresh weight by 150.8%, aboveground fresh weight by 31.3%, and hypocotyl length by 51.7% under chilling injury. we aim to provide an approach to develop and utilizate of LDHs-based nano iron fertilizer.

本研究合成并表征了MgFe层状双氢氧化物纳米颗粒（MgFe-layered double hydroxide nanoparticles，缩写MgFe-LDHs）；研究表明，在1~10 mg/L浓度范围内，该材料可提升黄瓜种子萌发效率与水分吸收能力，其中10 mg/L浓度通过根部施加方式，可在冷胁迫下最优促进种子出苗及幼苗生长。播种时采用10 mg/L的MgFe-LDHs（以下简称LDH）进行灌溉处理，在冷害条件下可使根长增加12.5%、侧根数量增加45%、根系鲜重增加150.8%、地上部鲜重增加31.3%，下胚轴长度增加51.7%。本研究旨在为基于LDHs的纳米铁肥料的开发与应用提供可行路径。
