STUDIES OF A GENETIC DISEASE OF TRIFOLIUM REPENS SIMULATING A VIROSIS
American Journal of Botany, 1946SEVERAL STUDIES have been made of plant diseases where genetic factors cause deformities similar to those caused by pathogenic agents. A correct diagnosis of such a condition occasionally proves difficult, particularly if the principal symptoms consist of irregular mottling of the leaves, but such cases are of especial interest to biologists, since ...

Quality characteristics of backcross hybrids between Trifolium repens and Trifolium ambiguum
Euphytica, 2002Two generations of novel backcross hybrids between white clover (Trifolium repens L.) and the related species Trifolium ambiguum,with white clover as the recurrent parent, were analysed for forage quality characteristics. Water soluble carbohydrate (WSC) levels, nitrogen concentrations (%N), and dry matter digestibility (DMD) were recorded for the ...

Cyanoglucoside biosynthesis in white clover (Trifolium repens)
Phytochemistry, 1976Abstract l -valine-(U- 14 C), isobutyraldoxime-(U- 14 C) and 2-hydroxyisobutyraldoxime-(1,3- 14 C) were fed to white clover shoots which contained or lacked cyanoglucoside. Labelling results indicated that plants which were unable to synthesize linamarin from these precursors lacked the ability to glucosylate 2-hydroxyisobutyronitrile.

Islands as refugia of Trifolium repens genetic diversity
Conservation Genetics, 2009Island populations are often thought to be more susceptible to the loss of genetic diversity as a consequence of limited population size and genetic drift, greater susceptibility to detrimental stochastic events and low levels of immigration. However the geographic isolation of islands may create refuges for native crop species whose genetic diversity ...

Transgenic White Clover (Trifolium repens)
2000White clover (Trifolium repens L.) is a perennial legume species that is an important component of many temperate zone pastoral animal production systems. In New Zealand, the United Kingdom, Ireland, Denmark, and to a lesser extent western and southern Europe, the USA, South America, and Australia, white clover is grown together with grasses, as a low ...

Interactions Between Rhizobia Nodulating Trifolium ambiguum and Trifolium repens in the Field
1998Trifolium ambiguum (Caucasian clover) is being released in New Zealand for use in regions where T. repens (white clover) growth is marginal. T. ambiguum has specific nodulation requirements and seed must be inoculated as appropriate strains of rhizobia are not found in NZ soils. T. ambiguum rhizobial strains (eg. ICC105) also rapidly nodulate T. repens

AGROTECHNOLOGICAL HARVESTING FEATURES OF TRIFOLIUM REPENS FOR SEEDS
Vestnik of the Russian agricultural science, 1970The features of the Lugovik new variety Trifolium repens seed yield formation dynamics with a different number of ripe ears were studied, and a comparative assessment of the effectiveness of methods of harvesting seed grass stand with the use of contact action desiccant based on the Reglon Super diquat in the Central Non-Black Earth Region was carried ...

Genetics of cyanogenesis in white clover (Trifolium repens)
Journal of Genetics, 19391. The presence and absence of cyanoglucoside in white clover are governed by a simple pair of factors which are designatedAc andac. 2. The cyanophoric character is completely, or almost completely, dominant to the acyanophoric. 3. The marked differences which occur between certain families, and in some cases between plants within the same families, in
