Abstract

Background: Sweet pepper (Capsicum annuum) is of considerable socio-economic importance and is among the most widely cultivated vegetables worldwide, occupying more than 20 000 km². Light-emitting diodes (LEDs), applied in continuous or pulsed modes, can increase yield and improve the phytochemical composition in indoor production systems. However, effective methodologies to define the optimal LED spectrum for maximizing growth across the full cultivation cycle - from seedling to fruit production - under controlled photoperiod conditions (14 h light/10 h dark) with pulsed lighting are lacking.

Results: Pepper crop performance was determined by seedling stem thickness, fruit fresh weight at harvest, and biomass development during the production stage. This was complemented by phytochemical analysis of the fruits (e.g., cinnamic acid derivatives and flavonoids). Full-spectrum LED lighting and pulsed light enhanced growth parameters in seedlings, increased phenol and flavonoid content in fruit, and improved photosynthetic activity in mature plants. In contrast, fruit yield (g per plant) and antioxidant capacity (FRAP) were significantly higher under a simple blue + red LED treatment.

Conclusion: The use of full-spectrum LED lights enhanced the growth and quality of seedling pepper plants, potentially providing a competitive edge in the market. Simple LED spectra can yield more fruit and antioxidants, whereas complete spectra can boost bioactive compounds. Pulsed light lamps can result in reduced energy costs of production, which would also benefit the profitability and sustainability of the system. © 2025 The Author(s).

连续光和脉冲光对辣椒产量和植物化学成分的影响。“Padron”。

背景：甜椒（Capsicum annuum）具有相当大的社会经济重要性，是世界上种植最广泛的蔬菜之一，占地面积超过20,000平方公里。在连续或脉冲模式下应用发光二极管（led）可以提高产量并改善室内生产系统中的植物化学成分。然而，在脉冲照明的可控光周期条件下（14小时光照/10小时黑暗），缺乏有效的方法来定义最佳LED光谱，以在整个栽培周期（从幼苗到果实生产）中最大化生长。结果：辣椒作物的生产性能由收获时的幼苗茎粗、果实鲜重和生产阶段的生物量发育决定。这是由果实的植物化学分析（例如，肉桂酸衍生物和类黄酮）补充。全光谱LED照明和脉冲光增强了幼苗的生长参数，增加了果实中酚和类黄酮的含量，提高了成熟植株的光合活性。相比之下，蓝+红LED处理显著提高了单株产量和抗氧化能力（FRAP）。结论：全光谱LED灯的使用促进了辣椒幼苗的生长和质量，可能在市场上提供竞争优势。简单的LED光谱可以产生更多的水果和抗氧化剂，而完整的光谱可以增加生物活性化合物。脉冲灯可以降低生产的能源成本，这也有利于系统的盈利能力和可持续性。©2025作者。约翰威利父子有限公司代表化学工业协会出版的《食品与农业科学杂志》。

期刊介绍： The Journal of the Science of Food and Agriculture publishes peer-reviewed original research, reviews, mini-reviews, perspectives and spotlights in these areas, with particular emphasis on interdisciplinary studies at the agriculture/ food interface. Published for SCI by John Wiley & Sons Ltd. SCI (Society of Chemical Industry) is a unique international forum where science meets business on independent, impartial ground. Anyone can join and current Members include consumers, business people, environmentalists, industrialists, farmers, and researchers. The Society offers a chance to share information between sectors as diverse as food and agriculture, pharmaceuticals, biotechnology, materials, chemicals, environmental science and safety. As well as organising educational events, SCI awards a number of prestigious honours and scholarships each year, publishes peer-reviewed journals, and provides Members with news from their sectors in the respected magazine, Chemistry & Industry . Originally established in London in 1881 and in New York in 1894, SCI is a registered charity with Members in over 70 countries.
