  • Developmental mutants of Phaseolus vulgaris L.

    Creator:
    Shii, Chou Tou
    Abstract:
    Hybrids with abnormal development were obtained when particular genotypes of Phaseolus vulgaris L. were crossed. The phenotypic aberrations of the F₁s included retarded growth, chlorosis of the trifoliate leaves and the formation of adventitious roots on the hypocotyls. The expression of the abnormalities was dependent on the temperature. At high...

  • Aroma comparison of 'Marion' (Rubus sp. L.) and 'Thornless Evergreen' (R. laciniatus L.) blackberries

    Creator:
    Klesk, Keith
    Abstract:
    'Marion' and 'Thornless Evergreen' blackberry volatiles were analyzed by capillary gas chromatography-flame ionization detection (GC-FED) and GC-mass spectrometry (GC-MS). Based on total percentage of FID area 'Thornless Evergreen' contains significantly more alcohols, hydrocarbons, and phenols than the 'Marion'; 'Marion' contains more acids and esters. Both cultivars contained comparable amounts of...

  • Perenniality in Poa annua L.

    Creator:
    Gibeault, Victor A.
    Abstract:
    Experiments were conducted to determine identification methods that could be used to differentiate annual and perennial plant types within the species Poa annua L. Thereafter, Poa annua plants were collected from numerous turfed areas in three Northern Pacific Coastal regions and identified as annual or perennial biotypes. It was found...

  • The developmental cytopathology of Prunus persica Batsch. and P. avium L. infected with X-disease and Albino disease respectively

    Creator:
    Florance, E. R.
    Abstract:
    In 1967, Doi et al. proposed the hypothesis that 'yellows type diseases' are caused by mycoplasma. Since then more than 60 yellows diseases have been associated with mycoplasma-like bodies (MLB) (Maramorosch, 1973). The majority of these associations are based upon electron microscopic observations of mycoplasma-like bodies in situ. However, little...

  • Correlations between horticultural characteristics and Fusarium root-rot resistance in Phaseolus vulgaris L.

    Creator:
    Wang, Theodora
    Abstract:
    To study the association between Fusarium root-rot resistance (Fusarium solani f. sp. phaseoli) and economically inportant characteristics of beans, 2259 lines each consisting of 30 plants were used. The lines were randomly selected for root-rot reaction, but were selected for differences in vigor and differences in plant and seed pigments,...

    Creator:
    Lynn, Jackson
    Abstract:
    Polypeptidyl derivatives of bovine pancreatic ribonuclease (RNase) containing two or three tyrosine chains with an average of two to three residues per chain have been prepared. The effects of various perturbants such as neutral salts, ethanol, urea and guanidine hydrochloride on the thermal transition of the derivatives have been studied....
