    Search for muon neutrino and antineutrino oscillations in the mass range 15〈Δm 2〈1,000 eV2/c4 (1985)

    Notes: Abstract A search for inclusive muon-neutrino (v µ) and muon-antineutrino $$(\bar v_\mu )$$ oscillations has been performed in the Fermilab narrow band neutrino beam using two detectors running simultanously at two distances from the neutrino source. The data show no evidence for either neutrino or antineutrino oscillations and rule out oscillations ofv µ or $$\bar v_\mu $$ into any other single type of neutrino for 15〈Δm 2〈1,000 eV2/c4 and sin2(2θ)〉0.02–0.40.

    Notes: Abstract Neutrino interactions with two muons in the final state have been studied using the Fermilab narrow band beam. A sample of 18v μ like sign dimuon events withP μ〉9 GeV/c yields 6.6±4.8 events after backgroud subtraction and a prompt rate of (1.0±0.7)×10−4 per single muon event. The kinematics of these events are compared with those of the non-prompt sources. A total of 437v μ and 31 $$\bar v_\mu $$ opposite sign dimuon events withP μ〉4.3 GeV/c are used to measure the strange quark content of the nucleon: $$\kappa = {{2s} \mathord{\left/ {\vphantom {{2s} {\left( {\bar u + \bar d} \right) = 0.52_{ - 0.15}^{ + 0.17} \left( {or\eta _s \frac{{2s}}{{u + d}} = 0.075 \pm 0.019} \right) for 100〈 E_v〈 230 GeV\left( {\left\langle {Q^2 } \right\rangle = {{23 GeV^2 } \mathord{\left/ {\vphantom {{23 GeV^2 } {c^2 }}} \right. \kern-\nulldelimiterspace} {c^2 }}} \right)}}} \right. \kern-\nulldelimiterspace} {\left( {\bar u + \bar d} \right) = 0.52_{ - 0.15}^{ + 0.17} \left( {or\eta _s \frac{{2s}}{{u + d}} = 0.075 \pm 0.019} \right) for 100〈 E_v〈 230 GeV\left( {\left\langle {Q^2 } \right\rangle = {{23 GeV^2 } \mathord{\left/ {\vphantom {{23 GeV^2 } {c^2 }}} \right. \kern-\nulldelimiterspace} {c^2 }}} \right)}}$$ using a charm semileptonic branching ratio of (10.9±1.4)% extracted from measurements ine + e − collisions and neutrino emulsion data.

    Pollen storage of Fragaria and Potentilla (1989)

    ISSN: 1573-5060

    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.

    Intergeneric crosses with Fragaria and Potentilla. I. Crosses between Fragaria moschata and Potentilla fruticosa (1985)

    ISSN: 1573-5060
    Keywords: Fragaria moschata ; Potentilla fruticosa ; intergeneric hybrids ; embryo culture ; parthenogenesis ; aneuploidy ; polyploidy ; chromosome elimination ; genetic variation

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    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.

    In tergeneric crosses with Fragaria and Potentilla. II. Crosses between the progeny of Fragaria moschata x Potentilla fruticosa and the original parents (1985)

    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.
