“…Further investigation is required to explore this mechanism since no literature was found that explained this phenomenon in rice. However, previous research has shown that the effect of maize kernel shading (40%) on %N at different stages showed a decrease in the %N content (up to 60%) compared to the control (ambient sunlight), which is not consistent with our study [27]. This crop difference suggests that plant physiological characteristics can impart significant crop variation for N uptake, retention, utilization, and isotopic fractionation.…”

“…Our results showed that dry matter accumulation was consistently and significantly reduced under the shading regimens, which was in accordance with previous observations ( Cui et al, 2015 ). Shading impaired sink strength including decreasing grains per ear and delaying development of endosperm cell ( Gao et al, 2017 ), which decreased kernel number per ear and 1000-kernel weight. Before flowering, shading affected the reproductive growth of the plant, and dry matter accumulation decreased.…”

“…With shading duration increasing, a source limitation in the reproductive stage may restrain the sink strength such as grain number 34 , 35 , which may have reduced the redistribution of stored dry matter from vegetative organs to grains after shading removal. Shading stress decreases the Pn of plants, affects the soluble carbohydrates available for transport to the spike of crops 36 , limits grain formation, and ultimately reduces grain yield.…”
