The oestrogenic activity of certain cultivars of subterranean clover (Trifolium subterraneum, L.) first became known through the observation of serious infertility in ewes in the early 1940's in Western Australia (Bennetts, Underwood and Shier-1946). The manifestations in commercial flocks of the syndrome "clover disease" have been dealt with in the preceding paper (Lightfoot 1974). The deleter...

The responses of selected clones of white clover (Trifolium repens) to simultaneous infection by the southern root-knot nematode (Meloidogyne incognita) and peanut stunt virus (PSV) were determined. Two white clover clones, which were resistant (NC-R) or sensitive (NC-S) to ozone injury, were evaluated. Plant growth and M. incognita reproduction were measured. Root, stolon, and top growth were ...

The genus Trifolium L. belonging to family Fabaceae is represented by about 255 species in the world. Two classifications based on sections or subgenus are commonly used researchers taxonomically evaluation of Trifolium. However, there still some confusing and complex situations taxonomy genus. For this reason, internal transcribed spacer (ITS) regions between rDNA genes nrDNA were examined for...

in a greenhouse experiment, the effects of glomus intraradices and indigenous mycorrhizal isolates from soils under plow and no-till treatments on the uptake of 32p placed at 1, 2.5 and 4 cm from the roots of white clover (trifolium repens) in 23, 37 or 46 days after planting were compared.spores of the indigenous fungi were mostly a mixture of glomus mossea, g. clarum, g. caledonium and g....

in order to estimate the nutrient value of three dominant range species; festucaovina, trifolium montanum and alopecurus textilis via proximate analyses and gas productiontechnique, samples were collected in three stages during grazing period from 26th may to 1thseptember in six areas of sabalan mountain in north west of iran. results showed thattrifolium montanum as a legume had higher values ...

in natural ecosystems, biological relationships have serious effects on system stability. allelopathic is negative or positive effect of a plant on other plant growth. today this word is used for rangelands, same as agricultural areas. because of good herbage production, medicago is most common plant in agricultural rotations and rangelands. therefore investigation of its allelopathic qualities...

BACKGROUND The hoverfly Microdon (Chymophila) katsurai Maruyama et Hironaga 2004 was speculated to be a myrmecophilous species associated with the ant Polyrhachis lamellidens based on observations of adults near the ant nest. However, there have been no reports regarding the observation of immature stages of this species in association with P. lamellidens. NEW INFORMATION For the first time, ...

The primary aim of the current study was to examine whether depleted cognitive resources might have ramifications for the formation of neutral and negative spontaneous false memories. To examine this, participants received neutral and negative Deese/Roediger-McDermott false memory wordlists. Also, for half of the participants, cognitive resources were depleted by use of an ego depletion manipul...
