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

Nitrogen (N) deficiency and weed infestation are the main factors limiting the yield and quality of organic soft winter wheat (Triticum aestivum L.). If forage legumes are associated with wheat, simultaneously or successively, they can help to reduce the

Endogenous hormones and polyamines (PAs) could interact to regulate growth and tolerance to water stress in white clover. The objective of this study was to investigate whether the alteration of endogenous indole-3-acetic acid (IAA) level affected other ...

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.

Multiple effects of secondary metabolites on amino acid cycling in white clover rhizosphere
Soil Biology and Biochemistry, 2018Secondary metabolites secreted by microbes and plants act as mediators in plant-microbe interactions including nutrient uptake. However, until now very little is known about their role in nutrient assimilation, particularly amino acids, which are ...

Improving white clover for Australasia
Crop & Pasture Science, 2012Improving the genetic merit of temperate forage legumes helps ensure profitability and sustainability of our Australasian pastoral industries. Today’s plant breeders are supported by a range of underpinning research activities including genetic resources exploration and enhancement, plant physiology, plant health, feed quality, agronomy, quantitative ...

The Journal of Agricultural Science, 1965
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 ...

Wax Microchannels in the Epidermis of White Clover
Science, 1967The application of conventional electron microscopy to the study of plant leaves and fruit readily displays the surface wax deposits, but not the wax pathways from the underlying cells. A modified freeze-etch technique shows both at the same time and indicates that wax is transported from the epidermal cells to the leaf surface in microchannels.

Coumestans in diseased white clover
Phytochemistry, 1971Abstract Four coumestans have been detected in white clover ( Trifolium repens ) infected with various foliar pathogens, and have been identified as coumestrol, 12- O -methylcoumestrol, trifoliol and 7,10,12-trihydroxycoumestan ( repensol ) by chromatographic and spectroscopic methods. Repensol has not previously been reported as a natural product.
