In this study, we investigated the possible effects of cobalt and boron nanoparticles as an inducer of the first stages of development (germination) of hard and soft wheat when simulating flooding as one of the limiting environmental factors. We also investigated the remote effect of treating wheat grains with nanoparticles when flooding was applied already at the tillering stage. To identify the effects of nanoparticles, we used morphometric, biochemical and phenotypic parameters of seedlings and plants of two wheat species differing in origin and the response of these parameters to flooding. Positive effects were found at the germination stage, increasing quantitative indicators under stress. The sensitivity of wheat species to flooding was different, which corresponds to historical and climatic aspects of cultivation. Sensitivity to stress effects associated with loss of germination, decreased growth and photosynthesis was shown for both species. Treatment with cobalt and boron nanoparticles enhanced adaptation to stress and improved photosynthetic parameters, but the encouraging results under stressful conditions were ambiguous and in the case of soft wheat could lead to deterioration of some parameters. Thus, the use of boron and cobalt nanoparticles has potential for reducing productivity under stress, but requires a detailed assessment of the cultivation protocol depending on the genotype.
在本研究中，我们模拟洪水这一限制环境因素之一，调查了钴和硼纳米颗粒作为硬粒小麦和软粒小麦发育（发芽）第一阶段诱导剂的可能影响。我们还研究了在分蘖期已遭遇洪水时，用纳米颗粒处理小麦籽粒的远程效应。为确定纳米颗粒的影响，我们使用了两种起源不同的小麦品种幼苗和植株的形态测量、生化和表型参数，以及这些参数对洪水的响应。在发芽阶段发现了积极影响，增加了胁迫下的定量指标。小麦品种对洪水的敏感性不同，这与种植的历史和气候方面相对应。两种小麦品种对与发芽丧失、生长和光合作用下降相关的胁迫影响均表现出敏感性。用钴和硼纳米颗粒处理可增强对胁迫的适应性并改善光合参数，但在胁迫条件下令人鼓舞的结果并不明确，对于软粒小麦而言，可能导致某些参数恶化。因此，使用硼和钴纳米颗粒在胁迫下具有降低生产力的可能性，但需要根据基因型对种植方案进行详细评估。
