Perennial clovers are being evaluated for their potential to reduce groundwater levels in Australian cropping zones where many soils are considered too acidic for reliable lucerne nodulation. However, the release of effective inocula for perennial clovers into such areas where sub clover is the predominant legume, could potentially compromise nitrogen fixation from this valuable annual clover if the symbiosis between the new inoculants and sub clover is not optimal. Studies were therefore designed to increase our understanding of these symbiotic interactions to optimise the management of legum

Nitrogen fertilization, however, produced greater accumulations in all evaluations. Genetic diversity among 128 isolates from the lower Caucasus was significant.

[Truncated abstract] Evolution in two genetically diverse sown populations of subterranean clover (Trifolium subterraneum L.) was examined over 16 years at Mt Barker, a long growing season site, and at Nabawa, a short growing season site, in south-west Western Australia. One population consisted of a mixture of 40 strains sown in equal proportions, while the other was a bulk-hybrid population consisting of F2 seed from 253 crosses. Seed harvested annually and kept in cold storage was grown in an irrigated common garden at the University of Western Australia Field Station at Shenton Park, alon

Red clover (Trifolium pratense L.) contains isoflavones, which are of interest because of their benefits for human health as well as their adverse effects on the fertility of farm animals. Isoflavone concentration in 10 cultivars ranged from 8923 to 12753 mug g-1 DM averaged across sites, harvests, and years. One cultivar, 'Start', distinguished itself with particularly low isoflavone levels. Concentrations varied according to plant part with leaves having the highest levels followed by stems and inflorescences, when averaged across maturity levels and cultivars (11970, 4896 and 3297 mu

The significance of motility for root colonisation and nodulation was investigated by comparing the behaviour of well-characterised motile (MNF 1000) and non-motile (MNF 1005) strains of Rhizobium leguminosarum bv. trifolii. A very small volume (5 pi) was used to inoculate clover (Trifolium subtcrrancum cv. Mt. Barker) roots to avoid mass flow of organisms. The nodulation pattern was used as an index of the colonisation of the roots; it was assessed by a grid-sectioning technique which divided the soil column into 1 cm cubes, or by gamma-ray computer assisted tomography (CAT) scanning.

This study explores the utility of these approaches for understanding the invasion of Trifolium (true clover) species in New Zealand.

Resumo:

The objective of this study was to evaluate the short-term (one-year) biomass production in red clover and to obtain an estimate of the heritability of this characteristic. Progenies from parents with high biomass had higher biomass than those from parents with low biomass or having one parent in each category. The narrow-sense heritability estimated from mid-parent offspring regression was 0.23, from parent-offspring correlation was 0.22, and realized heritability was 0.15, indicating that progeny testing would be required for successful selection of populations with greater biomass productio

Resumo:

The factors influencing senescence in white clover (Trifolium repens L.) are of considerable importance to the pastoral sector of New Zealand’s economy. The plant hormones, ethylene and the cytokinins, have been implicated as having opposing influences on senescence. This project focused on the cytokinins. The rate limiting step in cytokinin biosynthesis is catalysed by isopentenyl transferase (IPT) and the primary enzyme in the degradation of cytokinins is cytokinin oxidase/dehydrogenase (CKX). Both IPT and CKX genes are present as multi-gene families. A reduction in the level of active cytok
