White clover (Trifolium repens L.) is an important perennial legume forage and ornamental plant, widely distributed cultivated in the world. Recently, white plants showing symptoms of leaf mosaic redding were observed Hohhot, Inner Mongolia China. In this work, flexuous filamentous viral particles about 700 × 13 nm size symptomatic samples. The infection yellow vein virus (ClYVV) was confirmed ...

Shade-avoidance is a major adaptive response of plants, and is usually considered to be controlled by phytochromes through the perception of changes in the red:far red light ratio. However, few studies on the effects of blue light (BL) and of light intensity [photosynthetically active radiation (PAR)] on light-grown plants have been conducted, especially concerning changes in PAR at constant BL...

Methane is a major constituent of greenhouse gas (GHG) emissions from ruminants, and mitigation strategies are needed to alleviate this negative environmental impact while maintaining the other benefits grazing systems. Forages containing plant-specialized metabolites (PSM), particularly condensed tannins, may help reduce enteric methane (CH4) emissions. However, information on in vivo CH4 cows...

Cereal-legume intercropping is important in many low-input agricultural systems. Interactions between combinations of different plant species vary widely. Field experiments were conducted to determine yield formation regularities and competition effects oat (Avena sativa L.)–black medick (Medicago lupulina L.), oat–white clover (Trifolium repens oat–Egyptian (T. alexandrinum L.) under organic f...

The aim of the present study was to analyze effects two arbuscular mycorrhizal fungi (AMF), Funneliformis mosseae and Paraglomus occultum, on leaf water status, root morphology, sugar accumulation, abscisic acid (ABA) levels, malondialdehyde (MDA) content, antioxidant enzyme activities in white clover (Trifolium repens L.) exposed well-watered (WW) drought stress (DS) conditions. results showed...

1. Two experiments are described in which kinetic aspects of calcium metabolism were studied in housed lactating sheep consuming different fresh herbage species. The importance of protein supply was also investigated. 2. In Expt. 1, two groups (n 4) were offered, ad lib., a freshly cut ryegrass (Lolium perenne L.)-white clover (Trifolium repens L.) pasture containing 5.48 g Ca/kg dry matter (DM...
