INFLUENCE OF TEMPERATURE ON THE AVAILABILITY OF IRON TO AN OAT CROP

The availability of Fe-59 added as FeCl3∙6H2O to sandy-textured soils decreased in relation to the total amount of Fe taken up by oats when the temperature of the soil-root system was raised from 10 to 27 °C. When the soil temperature was raised to 27 °C, the ratio of Fe-59/total-Fe in the forage material of the oats decreased over the entire temperature range, even though maximum yield and total-Fe uptake occurred near 20 °C. Changing the aerial environment by lowering the dark-period air temperature from 25 to 10 °C markedly reduced the yield of dry matter and raised the concentration of total-Fe in the plant but did not consistently affect the ratio Fe-59/total-Fe. Incubating the soil for 30 days prior to adding the Fe-59 and seeding also reduced the proportion of Fe-59 in the plant material.

Influence of temperature on soil water content measured by ECH2O-TE sensorsThe aim of this study was to investigate the influence of temperature on water content value measured by ECH2O-TE sensors. The influence of temperature on measured soil water content values was clearly demonstrated. Soil water content values measured during the day apparently oscillated with oscillating soil temperatures. Average daily temperature and soil water content were calculated for selected periods. Regression relationships between deviations of soil temperature and soil water content from their daily average values were evaluated. Correlation between the soil water content and temperature deviations increase with the soil depth due to the lower influence of rainfall and evaporation at the soil surface on measured soil water content values in deeper soil layersegsoil water content oscillation was controlled mostly by oscillating temperature. The guideline values of linear regression equations (R2>0.8) were very similar, close to value 0.002 and the intercept values were equal to zero. The equation for recalculation of measured soil water content values at given temperature to reference soil water content for reference soil temperature, was propozed on the basis of this analysis.

Research was conducted to determine the influence of temperature on triallate absorption and metabolism in triallate-tolerant durum wheat (Triticum durum L. 'Monroe'), moderately tolerant Hard Red Spring (HRS) wheat (Triticum aestivum L. 'Coteau'), and susceptible HRS wheat, Alex. Uptake of 14C-triallate by the shoot was greater at 24 than at 8 °C by all species. Triallate uptake as influenced by soil temperature is a factor affecting triallate phytotoxicity to wheat. However, Monroe shoot meristematic tissue contained more 14C-label than Alex or Coteau, indicating that 14C-label content in the meristematic tissue was not related to triallate tolerance. Further, the coleoptile tissue of Monroe contained less 14C-label than Alex or Coteau. The coleoptile tissue did not prevent 14C-label entry into shoot tissue. Coleoptile tissue did not seem to be a factor influencing triallate tolerance. 14C-triallate concentration in the shoot related to triallate tolerance at both 8 and 24 °C. Triallate metabolism was apparently involved in differential tolerance among cultivars as the more tolerant Monroe and Coteau had more 14C-metabolites than susceptible Alex.

Oats (Avena sativa L. cv. Froker) were grown to initial panicle emergence in three day/night temperature regimes; H (32/26 C), W (27/21 C), and C (21/15 C). At initial panicle emergence, some plants were transferred to the other regimes until complete panicle emergence. Plants grown continuously in the W regime reached initial panicle emergence in 34 days and complete panicle emergence in 42 days. These stages were reached about a week later in C regime and about 2 wk later in H regime. As compared with plants retained at one temperature to complete panicle emergence, moving plants at initial panicle emergence from H to W or C, or from C to H or W, decreased time to complete panicle emergence by 4 to 6 days. However, complete panicle emergence was delayed 4 to 5 days when plants were moved from W to C or H. Dry matter yields and growth rates (mg/pot/day) of plants grown continuously in the same regime to initial and to complete panicle emergence were highest, and similar, in the W and C regimes, but were significantly lower in the H. As compared with plants retained at one temperature to complete panicle emergence, changing at initial panicle emergence from H to W or C increased dry matter yields and growth rates at complete panicle emergence, whereas changing from W or C to H decreased these parameters. Yields and growth were changed very little by change from W to C or from C to W.

Objective: To clarify the correlation between temperature and the COVID-19 pandemic in Hubei.Methods: We collected daily newly confirmed COVID-19 cases and daily temperature for six cities in Hubei Province, assessed their correlations, and established regression models.Results: For temperatures ranging from −3.9 to 16.5°C, daily newly confirmed cases were positively correlated with the maximum temperature ~0–4 days prior or the minimum temperature ~11–14 days prior to the diagnosis in almost all selected cities. An increase in the maximum temperature 4 days prior by 1°C was associated with an increase in the daily newly confirmed cases (~129) in Wuhan. The influence of temperature on the daily newly confirmed cases in Wuhan was much more significant than in other cities.Conclusion: Government departments in areas where temperatures range between −3.9 and 16.5°C and rise gradually must take more active measures to address the COVID-19 pandemic.

Atomic Form Factor

Temperature affects both elastic and inelastic scattering of electrons in a crystal. The Debye-Waller factor, B, describes the influence of temperature on the elastic scattering of electrons, whereas the imaginary part of the (complex) atomic form factor, fc = fr + ifi, describes the influence of temperature on the inelastic scattering of electrons (i.e. absorption). In HRTEM simulations, two possible ways to include absorption are: (i) an approximate method in which absorption is described by a phenomenological constant, μ, i.e. fi; - μfr, with the real part of the atomic form factor, fr, obtained from Hartree-Fock calculations, (ii) a more accurate method in which the absorptive components, fi of the atomic form factor are explicitly calculated. In this contribution, the inclusion of both the Debye-Waller factor and absorption on HRTEM images of a (Oll)-oriented GaAs crystal are presented (using the EMS software.Fig. 1 shows the the amplitudes and phases of the dominant 111 beams as a function of the specimen thickness, t, for the cases when μ = 0 (i.e. no absorption, solid line) and μ = 0.1 (with absorption, dashed line).

The article describes the main morphological and biological features of alfalfa varieties included in the State register of breeding achievements approved for use in the Central Chernozem zone of Russia. A total of 32 alfalfa varieties are included in the State register. This is 9 varieties of blue alfalfa (Medicago sativa L. subsp. Sativa) of domestic selection and 8 foreign, 11 varieties of variable alfalfa (Medicago sativa L. nothosubsp. varia (Martyn) Arcang.) domestic selection and 1 variety of foreign and 3 varieties of yellow alfalfa (Medicago sativa L. subsp. falcata (L.) Arcang.). It shows the average and maximum yield of varieties determined in the process of state variety testing, as well as independent evaluation in research institutions in the region. Varieties of blue alfalfa of domestic selection Kevsala, Elena, Satellite, Vavilovskaya Yubileynaya were the most productive. The average yield of dry matter of these varieties reaches 8.4–9.2 t/ha, the maximum — 15.3–17.7 t/ha. Alfalfa varieties Timbale and Galaxy were the most productive among foreign varieties: the average yield of dry matter was 8.1 and 8.3 t/ha, the maximum – 15.5 and 17.2 t/ha. Varieties of alfalfa variable Vitalina and Vela provided an average yield of dry matter of 7.6 and 9.0 t/ha, the maximum yield reached 15.4 and 18.1 t/ha.
