“…High light radiation and temperature frequently occur during the hot summer in south China. Our previous study showed that color shading nets covering decreased internal light density and temperature [5]. Also plant growth and photosynthetic rate of flowering Chinese cabbage could be improved under red shading net covering, compared with grey, blue and black shading nets [6].…”

The effect of color shading-nets (red net, blue net and silver net) and ordinary black net on plant growth and nutrient uptake of flowering Chinese cabbage (Brassica campestris L. ssp. chinensis var. utilis Tsen et Lee) were studied, with no net shading as the control. The results indicated that, compared with the control, red net covering increased plant height, leaf area and stem diameter of flowering Chinese cabbage. Red and blue nets covering enhanced the above ground fresh weight, while the silver and black nets covering decreased the above ground fresh weight. Shading net covering significantly improved the nitrogen (N) and potassium (K) content of flowering Chinese cabbage, while it had no significant effect on the phosphorus (P) content. Red and blue nets covering enhanced mineral nutrients uptake, while it was decreased under silver and black nets covering. Red and blue nets covering promoted plant growth and nutrients uptake of flowering Chinese cabbage and could be widely applied in leaf vegetable production.

We used a portable spectroradiometer to measure solar photon flux densities in the spectral regions of 400-500 nm (B), 500-600 nm (G), 600-700 nm (R), and 700-800 nm (FR) throughout one year at Ayabe city, Kyoto (135°16´E, 35°17´N). The relationships between sun elevation and the respective ratios of the R, G, and B components to photosynthetic photon flux density (PPFD: 400-700 nm) were relatively constant when the sun elevation was higher than 20°. Under these conditions, the G/PPFD ratio was almost invariant at 0.35-0.36. The R/PPFD and B/PPFD ratios averaged 0.35 and 0.30, respectively, and varied within a wider range of ±0.05 that depended on the weather. The relationship between sun elevation and the R/FR ratio was relatively constant when the sun elevation was higher than 15°, under which conditions it was almost always within the range of 1.0-1.2 regardless of the weather.

“…Significant and negative correlations between grain protein content and cooking and eating quality have been widely observed in rice [19][20][21]. Previous studies reported a decrease in the amylose content and an increase in the protein content of rice grains under weak light at the grain filling stage [22][23][24], which showed that insufficient solar radiation during the grain filling stage led to poorer milling, a poorer appearance, and a poorer cooking and eating quality in rice. However, shading during the early growth stage reduced the occurrence of chalkiness and had no effect on grain protein content, which improved the appearance and cooking and eating quality of rice to a certain extent [25].…”

As a growing abiotic stress, light deficient conditions seriously affect the yield and quality of rice. However, few studies focus on the effects of shading on grain quality at the booting stage and the responses of different hybrid rice cultivars to shading. Field experiments involving four representative rice (Oryza sativa L.) cultivars across no shading (CK) and 40% shading at the booting (S) and grain filling stages (SS) were conducted in 2021 and 2022. Compared with CK, S reduced grain yield by 53.0% but increased the head rice rate by 11.4% averaged across varieties and years. The chalkiness degree (CD) and chalky grain percentage (CR) were reduced by 73.0% and 61.6% in S due to its 45.3% lower total spikelets m–2, 44.0% lower grain–leaf ratio and 23.5% lower dry weight spikelet production efficiency, compared with CK. The CD and CR in SS were 49.5% and 41.0% higher and HR was 7.1% lower than that in CK. Shading significantly reduced amylose content, peak viscosity and breakdown value, but increased protein content and setback value, and the effects of SS were greater than S. Y-liangyou900 and Liangyoupeijiu showed better milling quality, while Y-liangyou900 and Chuanyou6203 obtained a better appearance and eating quality than the other varieties under both S and SS. In conclusion, shading at the booting stage significantly improved the milling, appearance and nutritional quality, and did not reduce the cooking and eating quality, but led to a significant decline in the grain yield of hybrid rice. Moreover, Y-liangyou900 exhibited better rice quality but lower yield under shading treatments. Therefore, more attention needs to be focused on screening shade-tolerant varieties using both yield and quality to cope with climate change in the future.
