    摘要 中英对照阅读

    Barely (Hordeum vulgare L.), an essential crop accounting for roughly 15% of global caloric consumption, confronts substantial risks from toxic metal pollution, especially drought stress, (Pb) and mercury (Hg) stress, endangering global food safety. The current research sought to examine synergistic impacts of abovementioned stressors and efficacy of 5-ureidohydantoin, rhizobacteria and non-wood-based biochar in promoting barley growth. Experimental design... ...点击完成人机验证后继续浏览

    大麦（Hordeum vulgare L.）是一种重要的农作物，占全球热量摄入的大约15%，面临着有毒金属污染特别是干旱、铅(Pb)和汞(Hg)压力的严重风险，威胁着全球食品安全。当前的研究旨在考察上述压力因素的协同影响以及尿素基二氢嘧啶（5-ureidohydantoin）、根际细菌和非木质生物炭在促进大麦生长中的功效。实验设计包括了24种处理组合，这些组合涵盖了干旱压力、铅压力（5 mg/kg）和汞压力（250和500 mg/kg），并使用不同剂量的生物炭和5-ureidohydantoin进行施用。根际细菌与5-ureidohydantoin结合可以促进大麦生长，通过促进根系发育、增强营养吸收和提高整体活力来实现这一点，其中5-ureidohydantoin有助于细胞分裂和伸长，而根际细菌则增强了营养的可获取性和根系完整性，从而加快了发芽过程、开花时间和产量。TJ-70大麦种子经过Agrobacterium rhizogenes处理后，在铅压力为5 mg/kg时，其根长达到了10.01 cm（对照组为6.31 cm）。该处理使根和茎的鲜重分别增加了23.7% 和 25.71%，而叶绿素含量在铅压力为5 mg/kg时达到最大值2.69 mg/g。研究表明，接受过根际细菌和5-ureidohydantoin处理的植物在发芽率（超过85%）、根长（平均27 cm）和茎长（平均29 cm）以及总生物量方面都比对照组有了显著提升。同时施用5-ureidohydantoin和黄麻生物炭可以在提高改良植株的叶绿素水平并减少电解质渗漏(EL)的情况下，增强大麦对金属和干旱压力的抵抗能力。此外，在铅压力下，电解质渗漏降低至11.4%，活力指数提升到1601.09。这些数据显示，生物炭和5-ureidohydantoin的使用可以缓解环境压力对大麦的负面影响。将此研究扩展到各种作物中进行评估，将有助于确定其更广泛的相关性；从而促进结合刺激剂如根际细菌和5-ureidohydantoin与有机及无机改良剂一起使用的综合作物管理策略的实施，最终增强农业韧性并保障全球食品安全。
