    Notes: [Auszug] In initial experiments mycelial felts grown on Raulin-Thom and Czapek-Dox media failed to produce liver lesions when fed to guinea pigs. The material so fed was also negative to the 'beaker test'. Subsequent experiments with a high-sporing strain of the fungus, grown on potato-carrot extract ...

    Notes: [Auszug] The native 'low tussock grasslands'1 of New Zealand, with Poa and Festuca spp. dominant, cover approximately 7 million acres and occur mainly in the South Island. Areas are found from sea-level to 3,000 ft. and they provide extensive grazing for sheep. Three locations were chosen for sampling, one ...

    Notes: [Auszug] A strain of Mortierella hygrophila Linn, was kindly supplied by Mrs. Turner of the Botany Department, University of Nottingham (Uni. Nott. No. 11- isolated by Claussen), and a single-spore isolation was made. The subsequent culture was employed in experiments and a subculture has been deposited at ...

    Notes: [Auszug] The present communication records the observation in the field of fungal mycelia occurring in quantity in soil, possibly associated with a measurable difference in structure. During a survey of the sand soils of the Manawatu County, a difference was noted between Himatangi sand under manuka scrub ...

    Notes: [Auszug] When heat-dried pasture samples containing the toxin are fed for 35 days, guinea pigs show liver damage. Using this tedious bio-assay technique, White2 has been able to prepare extracts containing the toxin, but progress has been delayed through the lack of a specific chemical test. Recently, ...

    Notes: [Auszug] The method used in recent experiments is described briefly as follows. Rod and tube, unassembled, were placed in a large test-tube and sterilized by dry heat (160 C. for 1 hr.). After cooling, sterile water agar was dispensed into the holes in the rod with a hypodermic syringe under aseptic ...

    Exudation of amino acids by intact and damaged roots of wheat and peas (1968)
    Springer
    Plant and soil 28 (1968), S. 193-207 
    Details
    ISSN: 1573-5036

    Notes: Summary Wheat and pea seedlings were grown aseptically in solution-culture and the total free amino nitrogen released by the roots was determined by a quantitative ninhydrin test. Amino nitrogen from wheat plants after 14 days growth was not detected by the test, indicating the release of less than 3 µg of amino nitrogen from a culture of 15 plants. Pea plants of the same age released from 2 to 7 µg per plant. Paper chromatograms of highly concentrated undisturbed solution-cultures revealed up to 13 amino compounds from wheat and 11 from pea. The pattern of amino acids in exudates was similar to that in crushed roots, except for an unidentified amino compound which was detected only in exuded material. The total amino nitrogen and relative proportions of several amino acids in the root exudates of sand-grown peas was influenced by several ratios of oxygen and carbon dioxide supplied to the root zone. Roots, experimentally damaged by swirling and rinsing in sand, released in 1 hour amino nitrogen of from 73 to 120 per cent of that released by ‘normal’ exudation over a 2-week period. Our findings suggest that experimental and environmental root damage may be responsible for a large proportion of organic materials released by growing plant roots.
