Global climate change is characterized by asymmetric warming,i.e.,greater temperature increases in winter,spring,and nighttime than in summer,autumn,and *** experiments were conducted using four wheat cultivars,namely‘Yangmai 18’(ym18),‘Sumai 188’(SM188),‘Yannong 19’(YN19),and‘Annong 0711’(AN0711),in the two growing seasons of 2019-2020 and 2020-2021,with passive night warming during different periods in the early growth *** treatments were night warming during the tillering-jointing(NW_(T-J)),jointing-booting(NWJ-B),and booting-anthesis(NWB-A)stages,with ambient temperature(NN)as the *** effects of night warming during different stages on wheat yield formation were investigated by determining the characteristics of dry matter accumulation and translocation,as well as sucrose and starch accumulation in wheat *** wheat yields of all four cultivars were significantly higher in NW_(T-J)than in NN in the 2-year *** yield increases of semi-winter cultivars YN19 and AN0711 were greater than those of spring cultivars ym18 and *** NW_(T-J)increased wheat yield mainly by increasing the 1,000-grain weight and the number of fertile spikelets,and it increased dry matter accumulation in various organs of wheat at the anthesis and maturity stages by increasing the growth rate at the vegetative growth *** flag leaf and spike showed the largest increases in dry matter ***_(T-J)also increased the grain sucrose and starch contents in the early and middle grain-filling stages,promoting yield ***,night warming between the tillering and jointing stages increased the pre-anthesis growth rate,and thus,wheat dry matter production,which contributed to an increase in wheat yield.

Metal-based surface plasmon resonance(SPR)plays an important role in enhancing the photonic spin Hall effect(SHE)and developing sensitive optical ***,the very large negative permittivities of metals limit their applications beyond the near-infrared *** this work,we theoretically present a new mechanism to enhance the photonic SHE by taking advantage of SiC-supported surface phonon resonance(SPhR)in the mid-infrared *** transverse displacement of photonic SHE is very sensitive to the wavelength of incident light and the thickness of SiC *** the optimal parameter setup,the calculated largest transverse displacement of SiC-based SPhR structure reaches up to 163.8 ym,which is much larger than the condition of ***,an NO_(2) gas sensor based on the SPhR-enhanced photonic SHE is theoretically proposed with the superior sensing *** the intensity and angle sensitivity of this sensor can be effectively manipulated by varying the damping rate of *** results may provide a promising paradigm to enhance the photonic SHE in the mid-infrared region and open up new opportunity of highly sensitive refractive index sensors.
