Abstract

Background: Selenium (Se) is a crucial component of selenoaminoacids and selenoproteins. Therefore, Se-enriched agricultural products can reduce health complications induced by Se deficiency.

Objective: This research was carried out to investigate the effects of Se bio-enrichment on Basil grown in calcareous and non-calcareous soil systems and also to evaluate the changes in Se concentration in the soil after harvesting.

Methods: The experiment executed in two calcareous and one non-calcareous soil systems, and different Se application methods (control, soil application, seed inoculation, foliar application, and soil + foliar application) were administered. Selenobacteria, a plant growth-promoting rhizobacteria (PGPR), derived from the soil was used as a biofertilizer, compared to the other Se sources.

Results: The results showed that both soil types and the methods of Se application had significant effects (P ˂ 0.01) on root and shoot dry weights and concentrations of P, K, Zn, Fe, and Se in both of the root and shoot. Shoot dry weight of plants treated with foliar Se was maximum in the calcareous soil. Compared to the control treatment, foliar application of Se increased shoot Se content in both calcareous and non-calcareous soils by 242% and 204%, respectively. Furthermore, the increase in shoot Se concentration in calcareous soil induced by Se application increased the concentration of other nutrients in the shoot and root. Plant growth parameters and concentrations of nutrients were significantly increased by using selenobacter inoculum.

Conclusion: The application of Se-containing compounds can improve vegetable quality. Considering the daily requirement of the human body for minerals and nutrients, enriching basil with Se can play an important role in community health. Moreover, some patents have reported the effectiveness of endophyte bacteria.

罗勒蔬菜不同硒源及富硒供应方法研究(以钙质和非钙质土壤系统为例)
背景:硒是硒氨基酸和硒蛋白的重要组成部分。因此,富含硒的农产品可以减少硒缺乏引起的健康并发症。目的:研究钙质和非钙质土壤系统中硒生物富集对罗勒生长的影响,并评价采收后土壤中硒浓度的变化。方法:在2个钙质土壤系统和1个非钙质土壤系统中进行试验,采用不同的硒施用方式(对照施用、土壤施用、种子接种、叶面施用和土壤+叶面施用)。与其他硒源相比,从土壤中提取的硒杆菌是一种促进植物生长的根菌(PGPR),被用作生物肥料。结果:土壤类型和施硒方式对根、地上部干重和根、地上部磷、钾、锌、铁、硒含量均有显著影响(P值小于0.01)。钙质土壤中叶片硒处理植株的茎部干重最大。与对照处理相比,叶面施硒使钙质和非钙质土壤的地上部硒含量分别提高了242%和204%。此外,施硒增加了钙质土壤地上部硒含量,增加了地上部和根部其他养分的浓度。接种硒杆菌可显著提高植株的生长参数和养分浓度。结论:应用含硒化合物可改善蔬菜品质。考虑到人体对矿物质和营养物质的日常需求,在罗勒中添加硒可以在社区健康中发挥重要作用。此外,一些专利已经报道了内生细菌的有效性。
