“…In the present research, younger plants produced lower canes and we obtained significantly higher canes for plants under covers, as in the study by Xu et al (2014). The highest canes were obtained from soil that was covered for the entire season with PP (155.4 cm) and PLA (156.5 cm) mulches.…”

A three-year experiment was set up to assess the effect of three mulch types on the growth and yield of 'Polka' autumn fruiting raspberry (Rubus idaeus L.). The experimental arrangement comprised four combinations of two parallel blocks, one of which was a field crop and the second was a covered crop in the form of a high tunnel with raised beds sides. The crop was grown on raised beds (approximately 30 cm high) covered with a mulch made of: 1) polypropylene non-woven (PP); 2) PP with a photodegradant; 3) polylactide nonwoven (PLA). A crop on a raised bed without any mulch was the control. Biometric, physiological and yield parameters were assessed and included the number of canes, plant height, chlorophyll content in the leaves, fruit yield, weight of 20 fruits and the extract content.The obtained results show that the height of the canes grown on PLA and PP mulch was significantly higher than for the PP with photodegradant. Cultivation on PP, PLA and PP with photodegradant mulch resulted in a significant increase in the weight of 20 raspberry fruits and higher chlorophyll content in the leaves compared to the control combination.Ke y wor d s: cultivation, soil cover, growth, Brix

Growing raspberries in polyethylene tunnels is becoming more and more common. We wanted to examine the effect of high tunnel growing conditions on yield and berry quality in three floricane raspberry cultivars, 'Glen Ample', 'Glen Dee', and 'Maurin Makea', under Northern high-latitude conditions. Compared to the open field, fruit yield per cane was doubled in the tunnel. Fruit bioactive properties, including phenolic compounds and antioxidant activity, were not affected by the tunnel growing conditions. Of the cultivars investigated, 'Glen Dee' fruit had the lowest concentration of total phenolics. In the open field, the total phenolics content in 'Glen Ample' berries was 48% higher than 'Glen Dee'. Berries grown in the open field had higher contents of soluble solids (°Brix) and higher titratable acidity than those grown in the tunnel. Additionally, 'Glen Ample' and 'Maurin Makea' berries were sweeter than 'Glen Dee' berries. In conclusion, raspberry production in polyethylene tunnels may provide major benefits through increased fruit yield. While fruit bioactive properties were not affected, sensory taste may be different, however, as berry sweetness and acidity were decreased in the high tunnel.

“…Flavonoids, anthocyanins and tannins are favoured, for example, in berry production, as they give flavour and colour, and are perceived to be healthy (Tomás-Barberán & Espín, 2001). It is desirable to increase tannins in tea bushes grown under shade cloth (to reduce the heat load) and flavonoids in soft fruits, which are often grown in polytunnels in northern Europe (Xu et al, 2014), and likewise tomatoes among those crops grown under cloches in southern Europe (Casilla, 2013) (Figure 2).…”

Societal Impact Statement The effective management of light is beneficial for growers of plants in greenhouses, polytunnels and under cloches. The materials and structures used to construct these environments often create light‐limited conditions for crops and change the spectral composition of sunlight they receive. Combining practical measures, drawn from knowledge of plant photobiology, allows growers to monitor, forecast and optimise conditions in their growing environment according to its geographical location and the crop grown. Improved management of light through these measures could be expected to improve food quality and yield, and potentially reduce use of energy, water and pesticides. Summary Horticultural production in greenhouses and in polytunnels expands the viable geographic range of many crop species and extends their productive growing season. These semi‐controlled growing environments buffer natural fluctuations in heat, cold and light and hold potential to improve food security with a low environmental footprint. Over the last decade, technological advances in cladding materials, smart filters, photo‐electric cells for energy production and LED lighting have created opportunities to improve the light environment within these structures. In parallel, there have been large advances in plant photobiology, underpinned by progress in identifying the mechanisms of photomorphogenesis and photoprotection, mediated by plant photoreceptors and their interactions, across regions of the spectrum. However, there remains unexploited potential to synthesise and transfer knowledge from these fields to horticulture, particularly with respect to tailoring the use of sunlight to specific locations and production systems. Here, we systematically explain (1) the value of modelling and monitoring patterns of sunlight to allow for informed design of the growth environment; (2) the means of optimising light conditions through selection of materials and structures; (3) the requirements of different crop plants in terms of the amount and spectral composition of light that will benefit yield and food quality; (4) the potential to combine this knowledge for effective management of the sunlight; and, finally, (5) the additional benefits these actions may bring to growers and society at large, beyond the crops themselves, in terms of water use and energy efficiency.
