摘要
在植物生产系统中,采前紫外线辐射处理已成为化学植保方法的一种有前途的替代方法,可用于预防真菌病害。在我们的研究中,芬兰中部的三个草莓(Fragaria x ananassa)栽培品种每晚都要接受通过 LED 技术(峰值为 276 纳米)提供的紫外线处理(20 秒,0.02 kJ/m²)。目的是评估紫外线处理在抑制白粉病(由 Podosphaera spp.引起)方面的效果,并评估其在连续两个生长季节中对作物产量、果实质量、坚实度、挥发性有机化合物 (VOC) 含量和叶片特性的影响。在整个试验过程中,紫外线处理成功地抑制了所有三个受试草莓品种白粉病的生长,且未对叶片造成任何可见的损害。在不影响果实大小的情况下,紫外线处理增加了上市果实的产量。对果实质量的影响因具体栽培品种、取样时间和年份而异。经紫外线处理后,冷藏 2-3 天后的果实硬度有所提高。我们的研究结果表明,紫外线处理可直接或通过病害管理间接改变水果的挥发性有机化合物含量,从而影响其香气。这些发现强调了紫外线处理在增强抗病性和提高特定水果属性方面的各种优势。这表明,将紫外线处理纳入植物生产系统,特别是在北欧地区的隧道栽培中,是改进整体作物管理策略的一种可行方法。
Impact of pre-harvest UVC treatment on powdery mildew infection and strawberry quality in tunnel production in Nordic conditions
Preharvest UVC radiation treatment has emerged as a promising alternative to chemical plant protection methods in plant production systems for preventing fungal diseases. In our study, three strawberry (Fragaria x ananassa) cultivars were subjected to nightly UVC treatment (20 s, 0.02 kJ/m²) delivered through LED technology (with a peak at 276 nm) within polytunnel conditions in Central Finland. The aim was to evaluate the effectiveness of the UVC treatment in inhibiting powdery mildew (caused by Podosphaera spp.), as well as to assess its impact on crop yield, fruit quality, firmness, volatile organic compound (VOC) profile, and leaf properties across two consecutive growing seasons. The UVC treatment successfully suppressed the growth of powdery mildew in all three tested strawberry cultivars throughout the experiment, without causing any visible damage to the leaves. The UVC treatment led to an increase in the crop yield of marketable fruits without affecting their size. The impact on fruit quality varied, depending on the specific cultivar, sampling time, and the year under consideration. Fruit firmness following 2–3 days of refrigeration improved due to the UVC treatment. Our findings suggest that UVC treatment can alter the fruit's VOC profile, either directly or indirectly through disease management, affecting its aroma. These findings emphasize the diverse advantages of UVC treatment in enhancing disease resistance and enhancing specific fruit attributes. This suggests the potential for integration of UVC treatment into plant production systems, particularly in tunnel cultivation within Nordic conditions, as a promising approach to improve overall crop management strategies.
期刊介绍:
Scientia Horticulturae is an international journal publishing research related to horticultural crops. Articles in the journal deal with open or protected production of vegetables, fruits, edible fungi and ornamentals under temperate, subtropical and tropical conditions. Papers in related areas (biochemistry, micropropagation, soil science, plant breeding, plant physiology, phytopathology, etc.) are considered, if they contain information of direct significance to horticulture. Papers on the technical aspects of horticulture (engineering, crop processing, storage, transport etc.) are accepted for publication only if they relate directly to the living product. In the case of plantation crops, those yielding a product that may be used fresh (e.g. tropical vegetables, citrus, bananas, and other fruits) will be considered, while those papers describing the processing of the product (e.g. rubber, tobacco, and quinine) will not. The scope of the journal includes all horticultural crops but does not include speciality crops such as, medicinal crops or forestry crops, such as bamboo. Basic molecular studies without any direct application in horticulture will not be considered for this journal.
