| 中文摘要 | 莖葉類蔬菜（HLVs）是養活全球許多人的重要園藝作物。全球人口的增加要求更多的種植系統，導致肥料過量使用和土壤鹽化等壓力，降低了作物的生產力和農業的可持續性。因此，開發能夠同時減少肥料使用和增加作物收穫的永續農業策略，對於農業來說是迫切的。一種具有生產吡咯喹啉醌（PQQ）能力的內生細菌Burkholderia seminalis 869T2被用作蔬菜幼苗的生物刺激劑，在溫室或田間條件下進行了應用。兩種全球重要的HLVs，包心菜和萵苣，被初步測試，並在兩個不同的季節進行了田間種植的進一步檢驗，以建立一個內生生物刺激劑（EBs）輔助的萵苣生產系統。在本研究中，我們確認了B. seminalis 869T2是HLVs的多功能EBs，它可以顯著促進植物生長，並通過增加收穫的頭部重量、大小和營養成分，提高作物的品質。此外，收穫時間提前了兩週，同時產品品質更高，每公頃的肥料成本節省了50%。我們的研究提供了一種田間EBs輔助的萵苣生產管理，可以降低成本，增加產品的價值。研究結果突出了內生細菌的重要性，它們因其與寄主的共生關係和在農業中的潛在用途，值得進一步研究。 |
| 英文摘要 | Heading leafy vegetables (HLVs) are essential horticultural crops that feed many people worldwide. An increasing global population demands more cropping systems, leading to stresses such as fertilizer overuse and soil salination, decreasing in crop productivity and agricultural sustainability. Hence, developing those eco-friendly farming strategies that could simultaneously reduce fertilizer usage and increase crop harvest is urgent for agriculture. An endophytic bacterium Burkholderia seminalis 869T2 with pyrroloquinoline quinone (PQQ) producing ability were applied as biostimulant for vegetable seedlings under greenhouse or field conditions. Two globally important HLVs, cabbage and head lettuce, were preliminarily tested, and further examinations under in-field farming during two different seasons were carried out to develop an endophytic biostimulants (EBs)-assisted lettuce production system. In this study, we confirmed that B. seminalis 869T2 is versatile EBs for HLVs, which significantly promote plant growth and enhance the qualities of crops by increasing the harvested head weight, size and nutrient composition. Nevertheless, the harvest was accelerated by two weeks, together with higher product qualities and 50% fertilizing cost savings per hectare. Our study provides an in-field EBs-assisted management for lettuce production that could decrease costs and increase the product’s value. The results highlight the importance of endophytic bacteria that deserve further investigation due to their enigmatic symbiotic relationships with their hosts and potential usage in the agro-industry. |
