In order to investigate the abiotic stress (drought) tolerance of oat ( L.) with silicon and sulphur foliar fertilisation treatments, and monitor the effect of the treatments on the physiology, production, stress tolerance, plant, and grain quality of winter oat varieties, a field experiment was conducted in the growing season of 2020-2021. As a continuation of our article, published in another Special Issue of Plants, in this publication we evaluate the effect of silicon and sulphur treatments on the quality of winter oats. The whole grain sulphur content was significantly different between varieties. The foliar fertiliser treatments caused greater differences in both the carbon and nitrogen, and sulphur contents in the green plant samples, compared to the differences measured in the grain. Foliar treatments had a significant effect on the sulphur content of both plant samples and grains. Significant differences in the Al, Ba, Ca, Cu, Fe, K, Mn, Mo, Na, Ni, P, Pb, Sr, and Zn contents of oat grains were measured, both between treatments and between varieties. Winter oat varieties did not respond equally to the foliar fertiliser treatments in terms of either macronutrient or micronutrient content. When P, K, Ca, Mg, and S were summarised, the highest values were in the control plots. Significant differences in protein content were identified between winter oat varieties in response to the treatments, but the varieties did not respond in the same way to different foliar fertiliser treatments. Based on our results, we recommend the use of foliar fertilisation in oats in drought-prone areas.
为了研究叶面喷施硅肥和硫肥处理对燕麦（L.）非生物胁迫（干旱）耐受性的影响，并监测这些处理对冬燕麦品种生理、产量、胁迫耐受性、植株和籽粒品质的作用，于2020 - 2021年生长季进行了田间试验。作为我们发表在《植物》另一期特刊上文章的延续，在本出版物中，我们评估了硅肥和硫肥处理对冬燕麦品质的影响。不同品种的全谷物硫含量存在显著差异。与籽粒中测得的差异相比，叶面施肥处理导致绿色植物样本中的碳、氮和硫含量差异更大。叶面处理对植物样本和籽粒的硫含量均有显著影响。在处理之间和品种之间，均测定出燕麦籽粒中铝、钡、钙、铜、铁、钾、锰、钼、钠、镍、磷、铅、锶和锌含量存在显著差异。冬燕麦品种在大量元素或微量元素含量方面对叶面施肥处理的反应并不相同。当汇总磷、钾、钙、镁和硫时，对照地块中的含量最高。在冬燕麦品种对处理的反应中，鉴定出蛋白质含量存在显著差异，但不同品种对不同叶面施肥处理的反应方式不同。基于我们的结果，我们建议在易干旱地区的燕麦种植中使用叶面施肥。
