Abstract

Background and aims

Application of organic manure improves strawberry yield, but the underlying physiological and molecular mechanisms remain largely unclear.

Methods

Here, by integrating physio-biochemistry, metabolome and transcriptome analyses, we evaluated the effect of organic manure on the yield and quality of strawberry. Using garden waste and vermicompost as organic manure sources, five fertilization treatments were carried out in strawberry cultivation, including no fertilization, full inorganic nitrogen fertilizer, reduced inorganic nitrogen fertilizer (70% N), 70% N plus garden waste and 70% N plus vermicompost.

Results

The application of organic manure increased the yield, ascorbic acid content, nutrient levels and sugar/acid ratio but decreased the organic acid content in strawberry fruits. Furthermore, the increased organic manure accelerated the synthesis of sugars, amino acids, phenolic volatiles and flavonoids in strawberry fruits by reprogramming the regulatory network of transcripts and metabolites.

Conclusion

This study will help to ascertain the positive effects of the application of organic manure on the quality of strawberry fruits at the molecular level.

有机肥提高了草莓的产量和品质，这归因于代谢重编程增加了氨基酸、糖酸比、类黄酮和酚类挥发物

摘要

背景和目标

施用有机肥可提高草莓产量，但其潜在的生理和分子机制仍不清楚。

方法

在这里，通过整合生理生化、代谢组和转录组分析，我们评估了有机肥对草莓产量和品质的影响。以园林废弃物和蚯蚓粪为有机肥源，对草莓栽培进行5种施肥处理，包括不施肥、全无机氮肥、减量无机氮肥（70%N）、70%N+园林废弃物和70%N+蚯蚓堆肥。

结果

施用有机肥提高了草莓果实的产量、抗坏血酸含量、养分水平和糖酸比，但降低了草莓果实的有机酸含量。此外，增加的有机肥通过重新编程转录物和代谢物的调节网络，加速了草莓果实中糖、氨基酸、酚类挥发物和黄酮类化合物的合成。

结论

这项研究将有助于从分子水平确定施用有机肥对草莓果实品质的积极影响。
