生物基磺酸盐改良剂对盐碱土的改良效果及油葵生长的影响 [PDF]
, 2018 为研发生态导向型盐碱地治理修复技术解决黄河河套宁夏平原土壤盐碱化,设计不同水平生物基磺酸盐改良剂用量(0、750、1 500、2 250、3 000kg·hm-2)进行盆栽试验。结果表明,生物基磺酸盐改良剂可有效降低盐碱土pH和全盐质量分数,促进油葵生长发育,但施用量过高会起到相反作用。当生物基磺酸盐改良剂施用量为2 250kg·hm-2时改良效果最佳:油葵蕾期土壤pH、全盐质量分数最低达到9.63和0.77g·kg-1,较对照（CK）分别下降6.14%和62.07%;油葵叶片抗氧化保护酶过氧化氢酶 ...

Advances in Salt Tolerance Ability of Arbuscular Mycorrhizal Fungi-plantSymbionts [PDF]
, 2016 土壤盐碱化严重制约农业发展并影响生态环境.丛枝菌根真菌(AMF)与植物形成的共生体作为生态系统的有机组成部分,因其形成的广泛性,可增强植物抗盐碱胁迫的能力,具有不可忽视的生态调节作用.本文从盐胁迫对AMF发育的影响、盐胁迫下AMF对植物生长的影响、AMF增强植物耐盐性的内在机制等3个方面阐述了丛枝菌根真菌-植物共生体耐盐性的机制 ...

Shuitu Baochi Xuebao, 2019 以文冠果（Xanthoceras sorbifolia）1年生幼苗为研究对象，通过控制条件下的盆栽试验，研究不同盐碱胁迫条件对文冠果幼苗的水力学特征和碳素分配的影响。结果表明：（1）盐碱胁迫显著降低文冠幼苗存活率、株高和基径、不同部位生物量、凌晨水势、根水力学导度、光合速率和气孔导度；（2）随盐碱胁迫强度增加，植株各部位非结构碳含量均先升后降，且碱性盐胁迫对植株的伤害显著大于中性盐胁迫和混合盐碱胁迫，盐度和pH有显著的交互增强效应，碱性盐比例增加会加重胁迫危害；（3）盐碱胁迫显著限制幼苗根系吸水能力 ...

Comparative Proteomics of Proteins in Sinonovacula constricta Hemolymph under Low Salinity [PDF]
, 2004 应用双向聚丙烯酰胺凝胶电泳技术及图像分析技术寻找缢蛏在低盐环境压力下血淋巴内40kD以下小分子蛋白质组差异,制成肽质指纹图谱,MALDI-TOF-MS测序,通过数据库检索快速鉴定蛋白质或多肽。研究结果表明:低盐压力下,缢蛏血淋巴内有多种蛋白质发生变化,共鉴定出包括磷脂酶A2(Phospho lipaseA2)、锌指蛋白(ZincFingerProtein)等6种蛋白或多肽,其功能涉及营养、基因表达及蛋白合成调控等方面,说明其血淋巴在缢蛏的防御体系中具有关键性作用。The differences of ...
