Abstract

Protected cultivation systems, such as high tunnels, have gained popularity for their ability to enhance growth conditions and extend the growing season of horticultural crops. The choice of the covering film in these systems can significantly impact crop productivity and quality while influencing pest and pathogen incidence. This study aimed to evaluate the yield, physiological responses, and nutritional quality of green and purple basil grown in high tunnels using different plastic film covers. The study was conducted in Central Pennsylvania using twelve research high tunnels covered with four alternative polyethylene films with varying light diffusion and ultraviolet (UV) radiation transparency levels: TuffLite IV (TIV), KoolLite Plus (KLP), UV-transparent (UVT), and UV-opaque (UVO). Green ‘Genovese Compact Improved’ and purple ‘Amethyst Improved’ basil (Ocimum basilicum L.) cultivars were grown as test crops. The plastic covering film had a significant effect on the growth of both basil cultivars, with a significant interaction between the film and basil genotype. Green basil generally exhibited higher fresh and dry biomass compared to purple basil, and the film effect varied with the basil genotype. Leaf area, stem, leaf, and total plant biomass were influenced by the plastic cover, with UVO and UVT films resulting in higher biomass production. The plastic covering films showed varying effects on the mineral content, total chlorophyll, carotenoids, total phenolic compounds, and antioxidant activity, with UVO and UVT films often resulting in improved nutritional quality compared to traditional films. Furthermore, covering films influenced the downy mildew severity on both cultivars and the UVT film consistently limited the severity of the foliar disease in both genotypes. Overall, this study highlights the importance of selecting appropriate plastic covering films with varying levels of UV transparency in high tunnel production systems.

无土栽培的绿紫苏对高温室光选择性覆盖膜的反应

高架隧道等保护性栽培系统能够改善生长条件，延长园艺作物的生长期，因此广受欢迎。在这些系统中，覆盖膜的选择会极大地影响作物的产量和质量，同时还会影响病虫害的发生率。本研究旨在评估使用不同塑料薄膜覆盖物在高垄隧道中种植的绿色和紫色罗勒的产量、生理反应和营养质量。研究在宾夕法尼亚州中部进行，使用了 12 个研究型高架隧道，覆盖了四种不同光扩散和紫外线（UV）辐射透明度的聚乙烯薄膜：TuffLite IV (TIV)、KoolLite Plus (KLP)、紫外线透明 (UVT) 和紫外线不透明 (UVO)。试验作物为绿色的 "Genovese Compact Improved "和紫色的 "Amethyst Improved "罗勒（Ocimum basilicum L.）。塑料覆盖膜对这两种罗勒栽培品种的生长都有显著影响，薄膜与罗勒基因型之间存在显著的交互作用。绿罗勒的新鲜生物量和干生物量通常高于紫罗勒，薄膜的影响随罗勒基因型的不同而变化。叶面积、茎、叶和植物总生物量受塑料覆盖物的影响，UVO 和 UVT 薄膜的生物量更高。塑料覆盖膜对矿物质含量、总叶绿素、类胡萝卜素、总酚类化合物和抗氧化活性的影响各不相同，与传统薄膜相比，UVO 和 UVT 薄膜通常能提高营养质量。此外，覆盖膜对两种栽培品种的霜霉病严重程度都有影响，而 UVT 膜则持续限制了两种基因型的叶面病害严重程度。总之，这项研究强调了在高隧道生产系统中选择适当的、具有不同紫外线透明度的塑料覆盖膜的重要性。

期刊介绍： Horticulturae (ISSN 2311-7524) is an international, multidisciplinary, peer-reviewed, open access journal focusing on all areas and aspects of temperate to tropical horticulture. It publishes original empirical and theoretical research articles, short communications, reviews, and opinion articles. We intend to encourage scientists to publish and communicate their results concerning all branches of horticulture in a timely manner and in an open venue, after being evaluated by the journal editors and randomly selected independent expert reviewers, so that all articles will never be judged in relation to how much they confirm or criticize the opinions of other researchers.
