A tale of two grass species: Temperature affects the symbiosis of a mutualistic Epichloë endophyte in both tall fescue and perennial ryegrass
(Frontiers Media SA, 2020-05-08)
Many cool-season grasses form permanent, mutualistic symbioses with asexual Epichloë endophytes. These fungal symbionts often perform a protective role within the association as many strains produce secondary metabolites ...
Which rhizobia nodulate which legumes in New Zealand soils?
(New Zealand Grassland Association, 2015)
Recent work which genotypically characterised rhizobia of native, crop and weed legumes in New Zealand and examined their cross-nodulation ability is reviewed and related to earlier work with focus on New Zealand pasture ...
A study of the regenerative ability of yarrow (Achillea millefolium L.) rhizomes
(Lincoln College, University of Canterbury, 1984)
The regenerative ability of yarrow (Achillea millefolium L.) rhizomes was studied in a series of experiments at Lincoln College during 1981-83. Factors considered were: rhizome age, NO₃ concentration, correlative inhibition ...
The effect of Neotyphodium grass endophyte on alkaloid profiles, dry matter production and botanical composition of perennial ryegrass pastures
(Lincoln University, 2014)
This study involved three key experiments to examined the effect of Nil endophtye and novel endophyte strains (AR1, AR37, Wild-Type (WT) and NEA2) of perennial ryegrass on dry-matter (DM) production, botanical compositon, ...
Edaphic adaptation in species of Chionochloa
(Lincoln College, University of Canterbury, 1971)
Species of Chionochloa are tall tussock grasses which dominate the mountain vegetation in both islands of New Zealand. In the South Island they cover more than ten million acres of high country above about 600 metres and ...
Influence of soil pH, phosphorus and sulphur on the frequency of rhizobia genotypes found in four pasture legume species grown in an acid high country soil
(Lincoln University, 2014)
South Island hill and high country soils typically have deficiencies of nitrogen, phosphorus, sulphur and molybdenum. The soils often have low pH and as such, high levels of exchangeable aluminium and manganese, causing ...
Crossing the species barrier: investigating vertical transmission of a fungal endophyte from tall fescue within a novel ryegrass association
(Lincoln University, 2017-02-28)
Many Poaceae grasses form a symbiosis with Epichloë fungal endophytes. Initially a serious problem in agriculture due to their production of alkaloids toxic to livestock, endophyte strains were identified that were less ...
Novel markers for drought resistance in white clover
(Lincoln University, 2011)
Introduction. White clover (Trifolium repens L.) is an out-crossing allotetraploid (2n=4x=32) that acts like a diploid, also called amphidiploid. White clover is a forage crop with a high level of genetic heterogeneity, ...
Heavy metal stress can prime for herbivore-induced plant volatile emission
(Blackwell Publishing Inc., 2012-07)
Heavy metals are important pollutants that can severely impact ecological foodwebs. In addition to direct toxic effects, these contaminants have been suggested to disrupt chemical communication channels between plants and ...
Rumen function and foraging behaviour of non-lactating, pregnant dairy cows wintered on kale or grass
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2019)
An outdoor grazing study conducted with 45 non-lactating, pregnant dairy cows during winter measured dry matter (DM) intake, grazing behaviour, rumen pH, ammonia (NH₃) and volatile fatty acids (VFAs) of cows fed 11 (K11) ...
