Abstract

Fruits and vegetables that exhibit a higher chlorophyll content, as reflected in their visual appearance, are the preferred choice of consumers. The study aimed to evaluate the effects of Light Emitting Diodes (LEDs) on the physical, chemical, and pigmentation quality of bitter gourd using white, blue, and red at 1.5 W/135 lumens (Foshan Electrical and Lighting Co., Ltd [FSL], China). Bitter gourd, with a short postharvest life of 4-5 days due to physical and chemical disorders, was harvested weighing 300–400 g and 25 x 5 cm from the farm and subjected to varying illuminations within a 4-hour period for five days, with measurements taken daily. Statistical differences between treatments were observed in physicochemical parameters such as fruit shrivelling, yellowing, visual appearance, weight loss, dry matter content, total chlorophyll, pH values, and TA. The quality and shelf-life of bitter gourd fruits were found to be improved by the white LED. The visual appearance was maintained, and fruit shrivelling and yellowing were delayed, with lower weight loss observed. Slight changes in chlorophylls and carotenoids, vitamin C, and a shelf-life of 5 days were recorded.

受光照颜色影响的苦瓜（Momordica charantia L. cv. Jadeite）采后色素组成和理化特性

叶绿素含量较高的水果和蔬菜是消费者的首选。本研究旨在评估发光二极管（LED）对苦瓜物理、化学和色素质量的影响，使用的发光二极管有白色、蓝色和红色，亮度为 1.5 W/135 流明（佛山电器照明股份有限公司 [FSL]，中国）。由于物理和化学失调，苦瓜的采后寿命较短，只有 4-5 天。从农场采收的苦瓜重量为 300-400 克，大小为 25 x 5 厘米，连续五天在 4 小时内接受不同的光照，每天进行测量。不同处理之间的理化指标存在统计学差异，如果实干瘪、变黄、外观、重量损失、干物质含量、叶绿素总量、pH 值和 TA 值。白光 LED 改善了苦瓜果实的质量和货架期。视觉外观得以保持，果实干瘪和变黄的时间推迟，重量损失减少。叶绿素和类胡萝卜素、维生素 C 有轻微变化，货架期延长了 5 天。

期刊介绍： Advances in Horticultural Science aims to provide a forum for original investigations in horticulture, viticulture and oliviculture. The journal publishes fully refereed papers which cover applied and theoretical approaches to the most recent studies of all areas of horticulture - fruit growing, vegetable growing, viticulture, floriculture, medicinal plants, ornamental gardening, garden and landscape architecture, in temperate, subtropical and tropical regions. Papers on horticultural aspects of agronomic, breeding, biotechnology, entomology, irrigation and plant stress physiology, plant nutrition, plant protection, plant pathology, and pre and post harvest physiology, are also welcomed. The journal scope is the promotion of a sustainable increase of the quantity and quality of horticultural products and the transfer of the new knowledge in the field. Papers should report original research, should be methodologically sound and of relevance to the international scientific community. AHS publishes three types of manuscripts: Full-length - short note - review papers. Papers are published in English.
