Abstract：
BACKGROUND: The rate of germination and other physiological characteristics of seeds that are germinating are impacted by deep sowing. Based on the results of earlier studies, conclusions were drawn that deep sowing altered the physio-biochemical and agronomic characteristics of wheat (Triticum aestivum L.).
RESULTS: In this study, seeds of wheat were sown at 2 (control) and 6 cm depth and the impact of exogenously applied salicylic acid and tocopherol (Vitamin-E) on its physio-biochemical and agronomic features was assessed. As a result, seeds grown at 2 cm depth witnessed an increase in mean germination time, germination percentage, germination rate index, germination energy, and seed vigor index. In contrast, 6 cm deep sowing resulted in negatively affecting all the aforementioned agronomic characteristics. In addition, deep planting led to a rise in MDA, glutathione reductase, and antioxidants enzymes including APX, POD, and SOD concentration. Moreover, the concentration of chlorophyll a, b, carotenoids, proline, protein, sugar, hydrogen peroxide, and agronomic attributes was boosted significantly with exogenously applied salicylic acid and tocopherol under deep sowing stress.
CONCLUSIONS: The results of the study showed that the depth of seed sowing has an impact on agronomic and physio-biochemical characteristics and that the negative effects of deep sowing stress can be reduced by applying salicylic acid and tocopherol to the leaves.

摘要：
背景：正在发芽的种子的发芽率和其他生理特性受到深播的影响。根据早期研究的结果，结论是，深播改变了小麦（TriticumaestivumL.）的生理生化和农艺特性。
结果：在这项研究中，将小麦种子播种2（对照）和6cm深，并评估了外源施用的水杨酸和生育酚（维生素E）对其生理生化和农艺特性的影响。因此,在2厘米深度生长的种子见证了平均发芽时间的增加，发芽率，发芽率指数，发芽能量，种子活力指数。相比之下,6厘米深的播种会对上述所有农艺特性产生负面影响。此外,深植导致MDA升高，谷胱甘肽还原酶，和抗氧化剂酶，包括APX，POD,和SOD浓度。此外，叶绿素a的浓度，B,类胡萝卜素，脯氨酸,蛋白质，糖,过氧化氢,在深播胁迫下，外源施用水杨酸和生育酚可显著提高农艺属性。
结论：研究结果表明，种子播种深度对农艺和生理生化特性有影响，通过对叶片施用水杨酸和生育酚可以减轻深播胁迫的负面影响。
