    An investigation of morphogenesis within the genus Trifolium (1987)
    Springer
    Plant cell, tissue and organ culture 11 (1987), S. 37-46

    Notes: Abstract Morphogenic responses within the genus Trifolium were investigated by culturing various explants from seedlings of 72 species. Seedlings from 32 species produced callus alone, 40 produced adventitious shoots and/or roots, of which 25 species produced only shoots and 7 species formed only roots. Seedlings within each species also varied in their response to culture. The section of these seedlings most likely to produce adventitious shoots was the original shoot with the remnants of the surrounding hypocotyl and cotyledons, followed by the excised cotyledons themselves. Inter- and intra-varietal variation was observed in T. repens. Genotypes that produced adventitious buds were selected and crossed. An improvement in the proportion of the population capable of morphogenesis was observed in one cultivar.

    Condensed tannins in Trifolium species and their significance for taxonomy and plant breeding (1993)
    Springer
    Genetic resources and crop evolution 40 (1993), S. 7-13 
    Details
    ISSN: 1573-5109
    Keywords: bloat ; chemotaxonomy ; clover ; germplasm assessment ; plant breeding

    Notes: Summary Populations of 59 Trifolium taxa were screened for condensed tannin content using the vanillin-HC1 test. Eight species (T. arvense, T. aureum, T. badium, T. campestre, T. dubium, T. micranthum, T. patens and T. spadiceum) were shown to contain tannins. These species are all found in Section Chronosemium or Section Trifolium Subsection Arvensia of the genus, and thus presence of tannins appears to have a taxonomic significance. Screening populations within species showed differences in tannin content, but no plants in these species were free of tannins.
