Varietal Resistance to Clover Rot in White Clover
Nature, 1967CLOVER rot, caused by the fungus Sclerotinia trifoliorum Erikss., occurs in about 70 per cent of farm crops of red clover (Trifolium pratense) in Great Britain, according to a recent survey by Lester and Large1. But there are few reports of this fungus infecting white clover (Trifolium repens).

Uptake of Phosphate by White Clover
Journal of Experimental Botany, 1978The effect of pH on the electrogenic phosphate pump in white clover roots was investigated. It was found that the pump operated between pH 3-5 and 8-0 with an optimum at 4-3. External pH changes affected phosphate uptake and PD to the same extent so that a constant relationship between them was maintained.

Yields were recorded from a potato crop grown in the first year following a grazing trial comparing four strains of white clover, previously described in this journal (2 & 3). The Kent clover strain, which was the most persistent and which had produced the greatest live‐weight increase per acre, gave the highest yield of potatoes.

The phenols and prodelphinidins of white clover flowers
Phytochemistry, 2000White clover flowers (Trifolium repens L.) contain an abundance of phenolics, namely cis- and trans-p-coumaric acid 4-O-beta-D-glucopyranoside, the 3-O-beta-D-galactopyranosides of myricetin, quercetin and kaempferol together with two new derivatives namely myricetin 3-O-(6"-acetyl)-beta-D-galactopyranoside and kaempferol 3-O-(6"-acetyl)-beta-D ...

Variation in white clover for resistance to clover cyst nematode
New Zealand Journal of Agricultural Research, 1997Abstract The clover cyst nematode (Heterodera trifolii) infects white clover (Trifolium repens) in pasture throughout New Zealand, reducing plant growth and nutrition.

Tests for resistance to white clover mosaic virus in red and white clover
Annals of Applied Biology, 1982SUMMARYA range of red and white clover cultivars was tested for immunity to white clover mosaic virus. All plants became infected although some showed no symptoms. Enzyme‐linked immunosorbent assay (ELISA) and immunosorbent electron microscopy (ISEM) revealed significant differences in virus concentration between red clover cultivars and between clones

Plant parasitic nematodes in white clover and soil from white clover pastures in Australia
Australian Journal of Experimental Agriculture, 1997Summary. Seventeen sites, including locations in all the major white clover growing regions of Australia, were surveyed for the presence of plant parasitic nematodes in autumn and spring 1993. Trifolium repens L. cvv. Haifa and Irrigation, plus 1 other cultivar, were sampled at each site and nematodes extracted from roots, stems and soil.

The levels of infection with 4 viruses in young white clover ( Trifolium repens L.) plots sown in 1991 or 1992 were monitored at a total of 17 sites across the 6 States of Australia. Tests were undertaken for alfalfa mosaic (AMV), clover yellow vein (ClYVV), subterranean clover red leaf (SCRLV) (syn.

This poem on the white clover further defines the idea of a weed for someone possessed of the garden-sentiment. "If only its name were all forgot / And 'twere giv'n its chance to grow," the white clover would be appreciated as a flower rather than maligned as a weed, the poem asserts.

The traditional method of producing white clover seed is to grow it in a mixed sward with grass, usually ryegrass. Wild white clover was originally harvested from old permanent pastures, which were heavily grazed, especially in the spring. This system has been perpetuated in the production of white clover seed from leys, and in many areas where sheep ...
