“…Lu et al (2017) showed that the increase in plant uniformity can increase the light interception in the canopy. The radiation use efficiency during the vegetative period of maize was usually higher than that during the reproductive period (Shi et al, 2022), but increasing the light interception during the postsilking period can significantly increase the yield of maize (Zhou et al, 2021). Xiao et al (2020) simulated the future climate by 33 global climate models and two Representative Concentration Pathways, the results of which showed that the annual mean daily radiation decreased in the NCP, and the similar results also were found in the Northeast China (Koimbori, Wang, et al, 2022).…”

Under climate change background, long shady days during the summer maize growing season reduce the yield potential of this crop in the North China Plain. Optimizing the canopy structure can increase light interception to mitigate the negative effects of climate change. The spatial arrangement of each leaf along the stem affects the light interception that was influenced by cultivar characteristics. Field studies were carried out to select cultivars to optimize canopy structure in maize (Zea mays L.).Results indicated that the middle-upper canopy above the ear and two leaves below the ear position play a more important role than that of the lower canopy below the ear in deciding the final grain yield. The middle-upper canopy layer had larger leaf photosynthetic potential decided by the larger net photosynthesis rate and leaf area, as compared with the lower canopy. Larger FIPAR (the fraction of the photosynthetically active radiation) and less PAR (the photosynthetically active radiation) observed below the ear position were beneficial for yield improvement. Therefore, optimizing the middle-upper canopy structure by selecting cultivars to construct an ideotype plant in maize should be adopted for higher grain production.Abbreviations: DAS, days after sowing; FIPAR, fraction of the photosynthetically active radiation; FIPAR a , FIPAR of above the ear; FIPAR b , FIPAR of below the ear; FIPAR t , the total FIPAR; LA, leaf area; LPP, leaf photosynthetic potential; NCP, North China Plain; PAR, photosynthetically active radiation; PAR e , PAR above the ear canopy; PAR g , PAR at the ground level; PAR t , PAR of the whole canopy; P n , net photosynthesis.

“…Wang et al [ 32 ] reported that the WPSC cultivar of Yunuo_7 had better leaf appearance rate at high growing temperature (37.5 °C, southwest of China) than other corn cultivars adopted to northeast and north plain of China. Furthermore, there was an effect of solar radiation on growth components which were proportional to gross photosynthesis [ 33 ]. Results of Tollenaar et al [ 34 ] showed that more than a quarter of DM yield of corn was attributable to solar brightening during 1984 to 2013 in the US Corn Belt.…”

Little information exists on the variation in morphological characteristics, nutritional value, ruminal degradability, and molecular structural makeup of diverse whole-plant silage corn (WPSC) cultivars among different growing regions. This study investigated the between-regions (Beijing, Urumchi, Cangzhou, Liaoyuan, Tianjin) discrepancies in five widely used WPSC cultivars in China (FKBN, YQ889, YQ23, DK301 and ZD958), in terms of 1) morphological characteristics; 2) crude protein (CP) chemical profile; 3) Cornell Net Carbohydrate and Protein System (CNCPS) CP subfractions; 4) in situ CP degradation kinetics; and 5) CP molecular structures. Our results revealed significant growing region and WPSC cultivar interaction for all estimated morphological characteristics (P < 0.001), CP chemical profile (P < 0.001), CNCPS subfractions (P < 0.001) and CP molecular structural features (P < 0.05). Except ear weight (P = 0.18), all measured morphological characteristics varied among different growing regions (P < 0.001). Besides, WPSC cultivars planted in different areas had remarkably different CP chemical profiles and CNCPS subfractions (P < 0.001). All spectral parameters of protein primary structure of WPSC differed (P < 0.05) due to the growing regions, except amide II area (P = 0.28). Finally, the area ratio of amide I to II was negatively correlated with the contents of soluble CP (δ = -0.66; P = 0.002), CP (δ = -0.61; P = 0.006), non-protein nitrogen (δ = -0.56; P = 0.004) and acid detergent insoluble CP (δ = -0.43; P = 0.008), in conjunction with a positive correlation with moderately degradable CP (PB1; δ = 0.58; P = 0.01). In conclusion, the cultivar of DK301 exhibited high and stable CP content. The WPSC planted in Beijing showed high CP, SCP and NPN. The low rumen degradable protein of WPSC was observed in Urumchi. Meanwhile, above changes in protein profiles and digestibility were strongly connected with the ratio of amide I and amide II.

Our results revealed that significant difference were observed on growing region and WPSC cultivar interaction for all estimated morphological characteristics (P < 0.001), CP chemical profile (P < 0.001), CNCPS subfractions (P < 0.001) and CP molecular structural features (P < 0.05). Except ear weight (P = 0.18), all measured morphological characteristics varied among different growing regions (P < 0.001). Besides, WPSC cultivars planted in different areas had remarkably different (P < 0.01) CP chemical profiles and CNCPS subfractions. All spectral parameters of protein primary structure of WPSC differed (P < 0.05) due to the various growing regions, except amide II area (P = 0.28). Finally, the area ratio of amide I to II was negatively correlated with the contents of soluble CP (δ = -0.66; P = 0.002), CP (δ = -0.61; P = 0.006), non-protein N (δ = -0.56; P = 0.004) and acid detergent insoluble CP (δ = -0.43; P = 0.008), in conjunction with positively correlated with moderately degradable CP (PB1; δ = 0.58; P = 0.01). In conclusion, the current study suggested that even for the same WPSC cultivar, the morphological characteristics, protein nutritional values and rumen degradability significantly varied among different grown regions due to distinguished molecular structures.
