Fourier transform infrared photoacoustic spectroscopy (FTIR-PAS) was used to record the spectra of rice leaves for the effective diagnosis of nitrogen nutrition status. The band in the wavenumber range of 1680 to 1630 cm −1 was associated with amide I and that from 1570 to 1510 cm −1 with amide II. We attempted to use this information to characterize the nitrogen status in rice plants at different growth stages. The ratio of photoacoustic intensity of amide II to amide I was measured and applied as nitrogen status index, and considering the yields, the ratio showed a positive linear correlation (R 2 = 0.9) with the total nitrogen of rice leaves. The ratio at the tillering and full panicle stages were more suitable for diagnosis, a ratio of 0.4–0.55 indicated an adequate nitrogen status, ratios lower than 0.4 indicated a poor nitrogen status; whereas ratios greater than 0.55 indicated excessive nitrogen supply. Our study provides an effective and rapid strategy for nitrogen-supply assessment in rice based on FTIR-PAS, which can guide rational fertilization in rice production.","is_dataset_classified":null,"base_score":3.367295829986474,"endowment":3.367295829986474,"datacite_reuse_total":2,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"31452670","pmcid":"PMC6699123","openalex_id":"https://openalex.org/W2969524052","authors":[],"funders":[{"funder_name":"the National Key Basic Research Program of China","grant_id":"2015CB150403","title":null},{"funder_name":"the Key Research and Development Program of Jiangsu Province China","grant_id":"BE2017388","title":null},{"funder_name":"the “STS” project from Chinese Academy of Sciences","grant_id":"KFJ-STS-QYZX-046","title":null},{"funder_name":"the “STS” project from Chinese Academy of Sciences","grant_id":"KFJ-PTXM-003","title":null}],"total_grants":4,"fwci":1.9687,"citation_percentile":0.83732057,"influential_citations":0,"citation_trend":[{"year":2020,"count":4},{"year":2021,"count":7},{"year":2022,"count":4},{"year":2023,"count":3},{"year":2024,"count":5},{"year":2025,"count":3},{"year":2026,"count":2}],"oa_status":"gold","license":"cc-by","oa_locations":[{"url":"https://plantmethods.biomedcentral.com/counter/pdf/10.1186/s13007-019-0482-0","host_type":"journal"},{"url":"https://plantmethods.biomedcentral.com/counter/pdf/10.1186/s13007-019-0482-0","host_type":"publisher"},{"url":"http://link.springer.com/content/pdf/10.1186/s13007-019-0482-0.pdf","host_type":"publisher"},{"url":"http://link.springer.com/article/10.1186/s13007-019-0482-0/fulltext.html","host_type":"publisher"},{"url":"https://doi.org/10.1186/s13007-019-0482-0","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/31452670","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/6699123","host_type":"repository"},{"url":"https://doaj.org/article/3f8377f58dab40169830d63988cf3bde","host_type":"repository"},{"url":"https://plantmethods.biomedcentral.com/track/pdf/10.1186/s13007-019-0482-0","host_type":"Unpaywall"},{"url":"https://europepmc.org/articles/PMC6699123","host_type":"Europe_PMC"},{"url":"https://europepmc.org/articles/PMC6699123?pdf=render","host_type":"Europe_PMC"}],"fields_of_study":["Spectroscopy and Chemometric Analyses","Water Quality Monitoring and Analysis","Advanced Chemical Sensor Technologies"],"mesh_terms":[],"keywords":["Fourier transform infrared spectroscopy","Photoacoustic spectroscopy","Photoacoustic imaging in biomedicine","Fourier transform","Infrared","Fourier transform spectroscopy","Materials science","Nitrogen","Spectroscopy","Analytical Chemistry (journal)","Infrared spectroscopy","Chemistry","Optics","Mathematics","Physics","Environmental chemistry","Astronomy","Organic chemistry","Rice leaves","Amides","Ftir-pas","Nitrogen Status Diagnosis"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Zero hunger"}],"linked_datasets":[{"doi":"10.6084/m9.figshare.10040570.v1","title":"MOESM1 of Rapid diagnosis of nitrogen status in rice based on Fourier transform infrared photoacoustic spectroscopy (FTIR-PAS)","publisher":"figshare","resource_type":"JournalArticle"},{"doi":"10.6084/m9.figshare.10040570","title":"MOESM1 of Rapid diagnosis of nitrogen status in rice based on Fourier transform infrared photoacoustic spectroscopy (FTIR-PAS)","publisher":"figshare","resource_type":"JournalArticle"}],"clinical_trials":[],"software_tools":[],"database_accessions":[{"name":"doi"}],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-16T12:14:27.038982Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
