Phylogenetic diversity of bacterial communities differing in degree of proximity of Lolium perenne and Trifolium repens roots
The rhizosphere of Trifolium repens and Lolium perenne was divided into three fractions: the bulk soil; the soil adhering to the roots; and the washed roots (rhizoplane and endorhizosphere). After isolation and puri®cation of DNA from these fractions, 16S rDNA was ampli®ed by PCR and cloned to obtain a collection of 16S rRNA genes representative of the bacterial communities of these three fract...
متن کاملThe Growth-rate of Weaner Sheep on Irrigated Pastures
Groups of six to nine Merino Summary lambs were weaned in September (May drop) and December (September drop) on to three types of irrigated perennial pastureperennial ryegrass (Lolium perenne), Ladino white clover (Trifolium repens) and lucerne (Medicago sativa), and one irrigated annual pasture-subterranean clover ( Trifolium subterraneum) . The weight gain of the weaners on white clover was s...
متن کاملFoliar zinc biofortification effects in Lolium rigidum and Trifolium subterraneum grown in cadmium-contaminated soil
Zinc (Zn) is an important micronutrient that can alleviate cadmium (Cd) toxicity to plants and limit Cd entry into the food chain. However, little is known about the Zn-Cd interactions in pasture plants. We characterized the effects of foliar Zn application and Cd uptake by ryegrass (Lolium rigidum L.) and clover (Trifolium subterraneum L.) grown on Cd-contaminated soils; all combinations of fo...
متن کاملImpact of cadmium and zinc on root system of Lolium perenne and Trifolium repens.
Urbanization, industrialization and agricultural practices have resulted in soil contamination with heavy metals in many world areas. Phytostabilization is an emerging solution to limit pollutant dispersion out of the contaminated area without expensive costs (Vangronsveld et al., 2009). However, because of the heavy metal phytotoxicity, the implementation of a plant cover could be jeopardized....
متن کاملImpact of defoliation intensity and frequency on N uptake and mobilization in Lolium perenne.
The aim of the study was to evaluate the impact of defoliation intensity, defoliation frequency, and interactions with N supply on N uptake, N mobilization from and N allocation to roots, adult leaves, and growing leaves. Plants of Lolium perenne were grown under two contrasted N regimes. Defoliation intensity treatments consisted of a range of percentage leaf area removal (0, 25, 50, 75, or 10...
