Impact 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 کاملThe effects of arbuscular mycorrhizal fungi and root interaction on the competition between Trifolium repens and Lolium perenne
Understanding the factors that alter competitive interactions and coexistence between plants is a key issue in ecological research. A pot experiment was conducted to test the effects of root interaction and arbuscular mycorrhizal fungi (AMF) inoculation on the interspecies competition between Trifolium repens and Lolium perenne under different proportions of mixed sowing by the combination trea...
متن کاملPhylogenetic 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 physical digestion of perennial ryegrass (Lolium perenne) and white clover (Trifolium repens) in the foregut of sheep.
Sheep were fed once daily with 300 or 600 g dried perennial ryegrass (Lolium perenne) or white clover (Trifolium repens). Total rumen contents were sampled once daily at various intervals up to 24 h after feeding for 6 d. Total weight of fresh rumen contents and dry matter (DM), organic matter and particulate matter concentrations were measured and the particle size distribution of rumen conten...
متن کاملEffects of water deficit and plant interaction on morphological growth parameters and yield of white clover (Trifolium repens L.) and ryegrass (Lolium perenne L.) mixtures
The effects of soil water deficit and interspecific plant interaction were studied on the dry matter (DM ) yield of white clover and ryegrass and on the morphogenesis of white clover. Plants were grown either: (1) individually (no interaction); or in a mixture of equal plant numbers with either (2) just shoot interaction, or (3) both shoot+root interaction. Plants were subjected to soil water d...
