Acid Toxicity

Experiments were conducted in controlled environmental chambers to determine the influence of temperature on the phytotoxicity of seven soil-applied herbicides. Diclofop {2-[4-(2,4-dichlorophenoxy)phenoxy] propanoic acid} soil incorporated or surface applied, was more toxic to wild oat(Avena fatuaL.) shoots at 10 and 17 C than at 24 C. Efficacy of diclofop was enhanced with soil incorporation. Diclofop toxicity to wild oat roots was not influenced by a change in temperature. EPTC(S-ethyl dipropylthiocarbamate) stimulated sugarbeet(Beta vulgarisL. ‘American Crystal Hybrid B’) shoot dry weight production at 10 C and caused dry weight reduction at 24 C. Atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine] toxicity to barley(Hordeum vulgareL. ‘Larker’) and alachlor [2-chloro-2′,6′-diethyl-N-(methoxymethyl)acetanilide] toxicity to oats(Avena sativaL. ‘Chief’) increased with increased temperature from 10 to 17 C. Temperatures within the range of 10 to 24 C did not affect trifluralin (α,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine) toxicity to barley or BAY-5653 [N-(2-benzothiazolyl)-N-methylurea] or chloamben (3-amino-2,5-dichlorobenzoic acid) toxicity to oats.

Influence Of Temperature On

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.

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).
