Data underlying the article: Chilling Tolerance of Basil Is Not Affected by UVB/C: A ¹H NMR Study

Basil (Ocimum basilicum L.) is susceptible to chilling injury (CI), leading to significant postharvest quality loss. This research aimed to improve basil’s chilling tolerance during cold storage through the application of supplemental UVB and UVC light at the end-of-production (EoP). Plant growth parameters (fresh weight and dry weight) were measured at harvest. The overall visual quality (OVQ) of basil leaves were scored and the maximum quantum yield of photosystem II (Fv/Fm) were measured to represent chilling damage at- and postharvest. Metabolite profiles of basil (cv. Dolly) leaves stored at 4 °C for up to 12 days were quantified by 1H NMR.<br>Light treatment: Control (red-white LED with no supplemental UV light), EoP-UVB (red-white LED with supplemental UVB light), EoP-UVC (red-white LED with supplemental UVC light)Postharvest storage time: 0, 3, 6, 9, and 12 days<br>

罗勒（*Ocimum basilicum* L.）易受冷害（chilling injury, CI）侵扰，会引发严重的采后品质损失。本研究旨在通过在生产末期（end-of-production, EoP）施加补充UVB与UVC光照，提升罗勒在冷藏过程中的耐冷性。收获阶段测定植株生长参数（鲜重与干重）；对罗勒叶片的综合外观品质（overall visual quality, OVQ）进行评分，并测定光系统II的最大量子产额（Fv/Fm），以此表征采前与采后的冷害程度。针对在4℃下贮藏长达12天的罗勒栽培品种‘Dolly’的叶片代谢物谱，采用1H NMR技术进行定量检测。
光照处理：对照组（无补充紫外光的红白LED光源）、EoP-UVB组（施加补充UVB光照的红白LED光源）、EoP-UVC组（施加补充UVC光照的红白LED光源）
采后贮藏时间：0、3、6、9及12天
