Influence of drought and rewatering on the pattern of photosynthate partitioning of winter wheat

Strategic Study of CAE 2012, Volume 14, Issue 3, Pages 59-64
In 2005—2006, two experiments were carried out to study the effect of drought stress on photosynthate partitioning patterns of winter wheat, as well as ecophysiological responses of winter wheat to drought and rewatering, at the Fengqiu Agro-ecological Experimental Station, Chinese Academy of Sciences. Jimai20 and Zhoumai18, two winter wheat cultivars differing in sensitivity to drought stress, were grown in the field under a retractable awning. In experiment, plants were subjected to severe drought stress at the reviving stage, and then rewatered respectively at the jointing stage (Wr1), the booting stage (Wr2) and the flowering stage (Wr3). Rewatering had compensatory effects on losses in winter wheat biomass induced by drought stress. Rewatering at the jointing stage had the greatest stimulating effect on biomass. Compensatory growth however did not lead to a full recovery of leaf area lost during the drought period. Rewatering at first suppressed root growth, and then stimulated it. Drought stress led to reduced photosynthate allocation in leaves and spikes, and increased photosynthate allocation in the stem, leaf sheaths and roots. Rewatering at the jointing stage, the booting stage and the flowering stage boosted photosynthate accumulation in leaves, the stem and grains respectively. Rewatering at all stages allowed full recovery of drought induced yield loss, by increasing number of spikelets at the jointing stage or 1 000 kernel weight at the booting and flowering stages.

Thermal and Mechanical Properties Optimization of ABO4 Type EuNbO4 By the B-Site Substitution of Ta Article

Engineering 2020, Volume 6, Issue 2, Pages 177-184 doi: 10.1016/j.eng.2019.12.006
Ferroelastic ABO4 type RETaO4 and RENbO4 ceramics (where RE stands for rare earth) are being investigated as promising thermal barrier coatings (TBCs), and the mechanical properties of RETaO4 have been found to be better than those of RENbO4. In this work, B-site substitution of tantalum (Ta) is used to optimize the thermal and mechanical properties of EuNbO4 fabricated through a solid-state reaction (SSR). The crystal structure is clarified by means of X-ray diffraction (XRD) and Raman spectroscopy; and the surface microstructure is surveyed via scanning electronic microscope (SEM). The Young's modulus and the thermal expansion coefficient (TEC) of EuNbO4 are effectively increased; with respective maximum values of 169 GPa and 11.2×10–6 K–1 (at 1200 °C). The thermal conductivity is reduced to 1.52 W·K−1·m−1 (at 700 °C), and the thermal radiation resistance is improved. The relationship between the phonon thermal diffusivity and temperature was established in order to determine the intrinsic phonon thermal conductivity by eliminating the thermal radiation effects. The results indicate that the thermal and mechanical properties of EuNbO4 can be effectually optimized via the B-site substitution of Ta, and that
this proposed material can be applied as a high-temperature structural ceramic in future.
