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 ...
The growth of lucerne following defoliation
(Lincoln College, University of Canterbury, 1970)
Much agricultural research has been directed towards maximizing pasture and crop yields. This has involved the identification of factors limiting growth and the formulation of management systems which will assist swards ...
Some aspects of the biology, population dynamics and economic status of Wiseana cervinata (Walker) (Hepialidae: Lepidoptera)
(Lincoln College, University of Canterbury, 1973)
Entomology, like many other biological disciplines has developed into a quantitative science in nearly all aspects of the subject. Insect ecology is no exception, and in fact, has probably received more attention recently ...
A comment on fisheries and agricultural trade relationships between New Zealand and Japan
(Lincoln College. Agricultural Economics Research Unit, 1978-02)
The primary objective of this paper is to assess the validity
of New Zealand's negotiating strategies with Japan over the question
of improved access for New Zealand's agricultural, forestry and fish
products in the ...
Population dynamics and pest assessment studies of grass grub (Costelytra zealandica (White), Melolonthinae) in the North Island of New Zealand
(Lincoln College, University of Canterbury, 1975)
Studies of the common grass grub (Costelytra zealandica (White)) covered two major aspects, population ecology and pest assessment. The object or these studies was to investigate the feasibility of developing models, ...
Hydrology and stream sediments in a mountain catchment
(Lincoln College, University of Canterbury, 1978)
New Zealand attitudes to soil and water conservation have their origins in
Europe and North America where legislation for the conservation of soil
and water resources preceded research by 20 - 30 years.
In the 1930's ...
New Zealand agriculture and oil price increases
(Lincoln College. Agricultural Economics Research Unit., 1979)
This paper is based on the assumptions that world oil
resources are finite and that world oil production will peak sometime
in the 1980s or 1990s (Hughes & Mesarovic 1978 : 139).
Such a scenario is now widely accepted ...
