“…Cucumber leaf area and dry matter were affected by UV blocking material, showing an increase when they were grown under UV exclusion conditions [52,60]. The same positive reaction was also evident in tomato [25], guar, urad and mung beans [36], eggplant [27], radish and welsh onion [44], broccoli and turnip (Brassica rapa L.) seedlings [47], soybean [49] and roses [54].…”

Plant Responses to UV Blocking Greenhouse Covering Materials: A Review

Pure polyethylene (PE) is enriched with several additives to make it a smart application material in protected cultivation, as a cover material for either greenhouses or screenhouses. When this material completely or partially absorbs ultraviolet (UV) solar radiation, then it is called UV blocking material. The current work presents a review on the effects of the UV blocking covering materials on crop growth and development. Despite the passage of several years and the evolution of the design technology of plastic greenhouse covers, UV blocking materials have not ceased to be a rather interesting technique for the protection of several vegetable and ornamental species. Much of the research on UV blocking materials focuses on their indisputable effect on reducing the activity of pests and viral-related diseases, rather than on the effects on the crop physiology itself. In the present paper, representative studies dealing with the effect of the UV blocking materials on the agronomic factors of different crops are presented and discussed. The results reveal that UV blocking materials have mainly positive effects on the different plant physiological functions, such as photosynthesis and transpiration rate, and on growth characteristics, while they might have a negative effect on the production and content of secondary compounds, as anthocyanins and total phenolics.

“…Plant responses alter leaf traits to block attractiveness to herbivores and entrance on host cells ( Caputo et al, 2006 ; Foggo et al, 2007 ; Mazza et al, 2013 ). On the other hand, reduction of UV light in plant growth facilities may disrupt visual cues that can decrease populations of insects in different crops ( Díaz et al, 2006 ; Legarrea et al, 2012 ; Gulidov and Poehling, 2013 ; Elfadly et al, 2016 ). Competitors of insects were reportedly less affected than their targets by altered UV exposure, and UV-exposed plant tissues may be capable of releasing increased levels of volatile compounds that are more efficient in attracting parasitoids ( Foggo et al, 2007 ; Legarrea et al, 2014 ; Dáder et al, 2015 ).…”

“…Competitors of insects were reportedly less affected than their targets by altered UV exposure, and UV-exposed plant tissues may be capable of releasing increased levels of volatile compounds that are more efficient in attracting parasitoids ( Foggo et al, 2007 ; Legarrea et al, 2014 ; Dáder et al, 2015 ). Depending on specific target plant–phyllosphere interactions, strategies for plant growth may include moderate exposure of plants to UV-B at early growth stages to induce defense mechanisms and not affect plant growth and yield, and later suppression of UV light to restrict insect entrance and herbivore attack ( Elfadly et al, 2016 ; Dáder et al, 2017 ). Each situation should be evaluated on a case-by-case basis, considering as well plant specific tolerance to UV irradiance and the tight control of UV conditions, including the spectrum provided by selected shading or light bulbs, and the intensity.…”

Influence of Light on Plant–Phyllosphere Interaction

Plant–phyllosphere interactions depend on microbial diversity, the plant host and environmental factors. Light is perceived by plants and by microorganisms and is used as a cue for their interaction. Photoreceptors respond to narrow-bandwidth wavelengths and activate specific internal responses. Light-induced plant responses include changes in hormonal levels, production of secondary metabolites, and release of volatile compounds, which ultimately influence plant–phyllosphere interactions. On the other hand, microorganisms contribute making some essential elements (N, P, and Fe) biologically available for plants and producing growth regulators that promote plant growth and fitness. Therefore, light directly or indirectly influences plant–microbe interactions. The usage of light-emitting diodes in plant growth facilities is helping increasing knowledge in the field. This progress will help define light recipes to optimize outputs on plant–phyllosphere communications. This review describes research advancements on light-regulated plant–phyllosphere interactions. The effects of full light spectra and narrow bandwidth-wavelengths from UV to far-red light are discussed.
