Relationships between soil water retention and soil composition
(Lincoln University, 1991)
Relationships between soil water retention and physical composition have been examined in this study, using a database of two independent sets of soils from two regions in New Zealand: Canterbury in the South Island (Set ...
The ryegrass endophyte in a cool-moist environment
(Lincoln University, 1996)
The endophytic fungus (Acremonium lolii) of perennial ryegrass (Lolium perenne) was studied in a field grazing experiment in a cool-moist environment, supplemented by more detailed glasshouse experiments on its interaction ...
Applying a land systems approach to describe and partition soil and forest variablility, Southern Mamaku Plateau, part of Kinleith Forest, New Zealand
(Lincoln University, 1999)
Kinleith Forest is a P. radiata dominated plantation forest situated on the edge of the Taupo Volcanic Zone in the central North Island, New Zealand. Approximately 35 000 ha of the forest is situated on the southern Mamaku ...
Role of mycorrhizae in rhizosphere processes and phosphorus dynamics
(Lincoln University, 2010-01)
The increased soil organic phosphorus (P) mineralization observed under trees compared to pasture has been attributed to the contrasting mycorrhizal associations of the two systems but to date, little work has been conducted ...
Assessment and management of hare impact on high-altitude vegetation
(New Zealand Department of Conservation, 1999-06)
Enhancement of the efficacy of the parasitoid, Microctonus hyperodae Loan (Hymenoptera: Braconidae) by provision of floral resources to improve biological control of its host, the Argentine stem weevil (Listronotus bonariensis) (Kuschel) (Coleoptera: Curculionidae)
(Lincoln University, 2005)
In this study, conservation biological control principles were applied to increase the efficacy of Microctonus hyperodae Loan (Hymenoptera: Braconidae), a parasitoid of the Argentine stem weevil (Listronotus bonariensis ...
Studies of Alfalfa mosaic virus in subterranean clover red leaf virus
(Lincoln College, University of Canterbury, 1978)
AMV was shown to be transmitted by sap, aphids and through lucerne seed but not by Cuscuta. Virus source and test plant influenced transmission frequency. Sap-inoculation tests showed that twenty species of plants were ...
Genotypic evaluation of Trifolium ambiguum
(Lincoln College, University of Canterbury, 1979)
A number of morphological, floral, rhizome, root and herbage characteristics were studied in order to describe genetic variation and environmental responses in T. ambiguum. From each of six lines, 30 genotypes were clonally ...
The reproductive seasonality and morphology of Argentine stem weevil Hyperodes bonariensis Kuschel (Coleoptera: Curculionidae) and the effect of host grasses on its pre-reproductive development
(Lincoln College, University of Canterbury, 1979)
In order to improve understanding of the phenology of Argentine stem weevil (Hyperodes bonariensis Kuschel), samples were collected at regular intervals from the field and the changes in their reproductive morphology ...
A study of the biology and population dynamics of Synanthedon tipuliformis (Clerck) (Lepidoptera: Sesiidae) in Canterbury, New Zealand
(Lincoln College, University of Canterbury, 1975)
The study covered the period August 1971 to February 1975 and was conducted in three blackcurrant plots. One plot comprised mature bushes that were pruned but not sprayed during the course of the study; the other two plots ...
