    Notes: Abstract The rate of neutrino- and antineutrino-induced prompt same-sign dimuon production in steel was measured using a sample of μ−μ− events and 25 μ+μ+ events withP μ〉9 GeV/c, produced in 1.5 millionv μ and 0.3 million $$\overline {v_\mu }$$ induced charged-current events with energies between 30 GeV and 600 GeV. The data were obtained with the Chicago-Columbia-Fermilab-Rochester (CCFR) neutrino detector in the Fermilab Tevatron Quadrupole Triplet Neutrino Beam during experiments E 744 and E 770. After background subtraction, the prompt rate of same-sign dimuon production is (0.53±0.24)×10−4 perv μ charged-current event and (0.52±0.33)×10−4 per $$\overline {v_\mu }$$ charged-current event. The kinematic distributions of the same-sign dimuon events after background subtraction are consistent with those of the non-prompt background due to meson decays in the hadron shower of a charged-current event. Calculations ofc $$\bar c$$ gluon bremsstrahlung, based on improved measurements of the charm mass parameter and nucleon structure functions by the CCFR collaboration, yield a prompt rate of (0.09±0.39)×10−4 perv μ charged-current event. In this case,c $$\bar c$$ gluon bremsstrahlung is probably not an observable source of prompt same-sign dimuons.

    Notes: Abstract Structure functions obtained from high energy neutrino and antineutrino scattering from an iron target are presented. These were extracted from the combined data of Fermilab experiments E616 and E701; these utilized narrow band beam runs between 1979–1982. The structure functions are used to test the validity of quarkparton model (QPM) predictions and to extract the QCD scale parameter Λ from fits to the Altarelli-Parisi equations.

    Notes: Summary Slash pine seedlings on Bladen, Leon, and Lakeland soils responded differently to P and N fertilization. Seedling growth was increased by all treatments on Bladen soil, whereas responses by seedlings on the other soils were nil. All soils were low in extractable P with both Bladen and Lakeland yielding 0.85 ppm P. Growth response to fertilizer was positive on Bladen soil because soil and tissue levels of P were raised above “critical” levels and other nutrients were present in adequate quantities. Tissue analyses indicated, and subsequent experiments utilizing macro- and micronutrients proved, that excess P applications reduced certain micronutrients to growth-limiting levels on both Leon and Lakeland soils. Best growth on Leon soil occurred when P and N were supplemented with Cu. On the Lakeland soil macronutrients supplemented with Cu, Mn, or Zn produced greatest growth. Toxicity levels of five micronutrients on the latter soil also were determined.

    Notes: Summary Crosses between Fragaria moschata (2n=42) and Potentilla fruticosa (2n=14) produced many seeds; about half of these germinated, but only nine plants were obtained from 554 seedlings. Five plants died without flowering, and four were vigorous but sterile. Four plants had the expected chromosome number (2n=28), one plant had 21 chromosomes, and four were aneuploid with 23, 24, 25 and 27 chromosomes respectively. Response to growth substances giving elongated stem internodes and swollen but not succulent receptacles provided evidence that two of the plant were hybrids. It is suggested that all nine plants originated from a normal fertilisation which was followed in some cases by chromosome elimination at an early stage of embryo development.

    Notes: Summary Low temperature and humidity were used for the storage of pollen of four species of Fragaria (2n=14, 42 and 56) and two species of Potentilla (2n=14). The stainability of Fragaria pollen was assessed over a number of years by use of aceto-carmine stain and its viability by cross-pollinations; stainability of Potentilla pollen was assessed by acetocarmine. Fragaria pollen so stored remained stainable for seven years and showed the ability to set seed for three years. over the latter period, aceto-carmine staining gave a reasonable prediction of seed set produced by the stored pollen of Fragaria and so is of value in estimating pollen viability in that genus. Potentilla pollen remained stainable for three years.

    Notes: Summary An aneuploid hybrid (2n=23) of Fragaria moschata (2n=42) and Potentilla fruticosa (2n=14) was backcrossed with pollen of both parents, separately and combined in a pollen mixture. Seven vigorous progeny were obtained. The origin of the exeptional chromosome numbers, 2n=44, 49, 63, 63, 65, 67, 67, is discussed, and it is shown that each of the numbers could be produced by the fertilisation of unreduced and double unreduced gametes of the hybrid by normally reduced gametes of one of the parental species.
