Trifolium subterranean

The case history of sub-clover (Trifolium subterranean) as an important pasture legume is of special interest, as an involuntary migrant from the Northern to the Southern hemisphere, the phenomenal success of which depended on inoculation.

In Australia, lambing in sheep has dropped to as little as 30% after grazing on subterranean clover. Trifolium subterraneum. The clover contains the isoflavonoids formononetin and genistein (Fig. 11.11). These compounds mimic the steroidal nucleus of the natural female hormone estrone. Alfalfa, M. sativa, and ladino clover. Trifolium repens, contain the even more potent isoflavonoid coumestrol. It is 30 times more active than genistein or formononetin, but occurs in lower concentrations in the plant (Shutt, 1976).

Many compounds with phytoalexin activity are also implicated in allelopathy between plants (Rice, 1984). For example, isoflavonoids are important phytoalexins (Ingham, 1982 Paxton, 1981 Dakora and Phillips, 1996) and allelochemicals (Tamura et al. 1967 1969) from the Leguminosae. Parbery et al. (1984) found that the isoflavonoids biochanin A, formononetin and genistein increased in subterranean clover by 62%, 123% and 75% respectively following infection by pepper spot (Leptosphaerulina trifolii). In comparison, Tamura et al. (1967 1969) isolated a succession of isoflavonoids (including biochanin A, formononetin and genistein) from the shoots of red clover (Trifolium pratense) that inhibited its own germination by 50% at concentrations of 50 ppm.

A large number of species of plants are known to contain compounds that have oestrogenic activity. Pasture plants containing these phytoestrogens are mainly of the species Trifolium subterraneum (subterranean clover), T. pratense (red clover), Medicago sativa (lucerne) and M. truncatula (barrel medic).The oestrogens in TrifoUum sp. are mainly isoflavones, whereas those in Medicago sp. are usually coumestans. 

Plant tissues/residues of wheat Triticum aestivum L. Coker 916 or 983 or Southern States 555 ), rye Secale cereale L. Abruzzi ), crimson clover Trifolium incamatum L. Tibbee ), and/or subterranean clover (T. subterranean L. Mount Barker ) were collected from litter bags half buried (i.e., the lower half of the bag was located within the soil) in the field plots (Blum et al. 1991) or from the soil surface (Blum 1997 Lehman and Blum 1997 Staman et al. 2001), freeze-dried, and stored in the dark at room temperature. The freeze-dried plant tissues/residues were ground just before analysis in a Wiley mill (20,40 or 60 mesh screen) and then extracted and analyzed by several different procedures ...
