摘要

本研究的目的是评估UV-C光对扁豆（Lens culinaris）的影响及其对螺旋藻的调理作用。主要发现是：（i）与对照（T0）和UV-C（T10=10分钟）照射的扁豆样品相比，扁豆的亮度呈现出显著的轻微变化（9%）。（ii）与T0（42.07μg mL-1）相比，总黄酮在10分钟内（49.18μg mL-1）增加了17%。（iii）用UV-C处理扁豆（0、5和10分钟）和用螺旋藻在水中吸收（0、0.5、0.75和1.5%）在幼苗中产生显著的统计差异（p≤0.05）。螺旋藻蓝细菌的引发提高了对UV-C辐射损伤的生理品质。（iv）小扁豆由于辐射而发生形态变化，发现由于UV-C的应用而导致的外种皮（外部保护层）区域（第1行）的损伤，其随着辐射暴露的增加而增加。紫外线照射10分钟后，细胞壁和蛋白体均受到损伤。然而，淀粉没有明显的损伤。（v） FT-IR表明，UV-C辐射没有引起淀粉化学结构的任何变化，但在3000至3 600 cm-1范围内强度的降低表明其含水量不同，而在1 600至1 700 cm-1之间的降低则归因于蛋白质二级结构的重组。

Effects of UV-C light and Spirulina maxima seed conditioning on the germination and the physical and nutraceutical properties of lentils (Lens culinaris)

. The aim of this research was to evaluate the effects of UV-C light on lentil ( Lens culinaris ) and its conditioning by Spirulina . The main findings were: (i) Lentil brightness presented a significant slight variation (9%) when compared to the control (T 0 ) and UV-C (T 10 =10 min) irradiated lentil samples. (ii) The total flavonoids tended to increase by 17% at 10 min (49.18 μg mL -1 ) compared to T 0 (42.07 μg mL -1 ). (iii) The conditioning of lentils with UV-C (0, 5, and 10 min) and the imbibition in water with Spirulina (0, 0.5, 0.75, and 1.5%) generated significant statistical differences (p ≤ 0.05) in the seedlings. The priming cyanobacte - ria Spirulina improved the physiological quality against damage caused by UV-C radiation. (iv) Morphological changes occurred in the lentils due to radiation, damage in the testa (protective layer on the outside) area (row 1) due to the application of UV-C was found, which increases with higher exposure to radiation. Through the application of UV-C for 10 min the cell wall and protein body were damaged. However, no damage to the starch is visible. (v) FT-IR indicates that the UV-C radiation did not induce any change in the chemical structure of the starch but, decreases in intensity within the range of 3 000-3 600 cm -1 indicated differ - ences in their water content, while those between 1 600-1 700 cm -1 were attributed to the reorganization of the secondary structure of proteins.

期刊介绍： The journal is focused on the soil-plant-atmosphere system. The journal publishes original research and review papers on any subject regarding soil, plant and atmosphere and the interface in between. Manuscripts on postharvest processing and quality of crops are also welcomed. Particularly the journal is focused on the following areas: implications of agricultural land use, soil management and climate change on production of biomass and renewable energy, soil structure, cycling of carbon, water, heat and nutrients, biota, greenhouse gases and environment, soil-plant-atmosphere continuum and ways of its regulation to increase efficiency of water, energy and chemicals in agriculture, postharvest management and processing of agricultural and horticultural products in relation to food quality and safety, mathematical modeling of physical processes affecting environment quality, plant production and postharvest processing, advances in sensors and communication devices to measure and collect information about physical conditions in agricultural and natural environments. Papers accepted in the International Agrophysics should reveal substantial novelty and include thoughtful physical, biological and chemical interpretation and accurate description of the methods used. All manuscripts are initially checked on topic suitability and linguistic quality.
