Effects of nematicides and plant resistance on white clover performance and seasonal populations of nematodes parasitizing white clover in grazed pasture.
Root-infecting nematodes are a major cause of white clover, Trifolium repens, not reaching its potential in New Zealand pastures. Resistance and/or tolerance are the preferred control options. Greenhouse-based, recurrent selection programs have developed resistance to Meloidogyne trifoliophila and Heterodera trifolii, and a field-based program has developed tolerance. Lines from these programs ...
متن کاملDivision of peribacteroid membranes in root nodules of white clover.
Division of peribacteroid membranes in the cytoplasm of root nodules of white clover was found, from a study of serial thin sections prepared for electron microscopy, to accompany division of the bacteroids. It was also observed that the peribacteroid membranes appeared to have adhered to various sites on the surface of the bacteroid envelope outer membranes. Wherever peribacteroid membranes we...

متن کاملThe specificity of arbuscular mycorrhizal fungi in perennial ryegrass–white clover pasture
For nitrogen to be transferred from a legume to grass through hyphae of arbuscular mycorrhizal fungi (AMF), as reported for a number of grass/legume combinations, the two species should be linked by a common hyphal network, which gives rise to the question of host–fungus preference. To examine the relative preference of perennial ryegrass and white clover for co-existing AMF, two experiments, a...
