PASTURE DEVELOPMENT ON UNPLOUGHABLE LAND

Proceedings of the New Zealand Grassland Association (1949)

E.A. Madden G. S. Harris Judith McKee

In this paper it is not the hill-country on which cultivating implements can be used that we are concerned with; it is all that steeper country which has been regarded variously as "marginal" or "deteriorated land," and which also is the really difficult country to manage and keep in a productive state.

Seed development in ryegrass, and in red and white clover

New Zealand Journal of Agricultural Research (1959)

E.O.C. Hyde M. Allison McLeavey G. S. Harris

Summary Studies were made of the rate of development of the seeds of perennial and Italian ryegrass, and of red and white clover. Three developmental phases can be recognised; the first a period of rapid growth and constant high moisture percentage, lasting about 10 days from pollination, during which viability is nil; a second phase of 10–14 days, when growth is slower and percentage moisture falls steadily, with sudden acquisition of viability; and a final phase of 3–7 days in which dry weight is constant but moisture decreases markedly. The effect of harvesting during these three phases is discussed, and mention is made of features useful in identifying the developmental stages.

Evaluation of microwave soil pasteurization for controlling germination of perennial ryegrass (Lolium perenne) seeds

Plant protection quarterly (2007)

Graham Brodie L. Pasma Hugh W. Bennett G. S. Harris J Woodworth

Lolium species are used as a major feed-source for stock around the world. Unfortunately there are a number of ryegrass species that have inherited the ability to survive a normally lethal dose of herbicide, which has prompted renewed interest in alternative control methods. Interest in microwave soil pasteurization for weed control began in the 1970s. Two experiments were conducted. The first considered the efficacy of microwave soil pasteurization for controlling Lolium perenne (perennial ryegrass) seed germination, while the second determined the influence of soil type and microwave power setting on soil heating rates. Microwave soil pasteurization killed perennial ryegrass seeds buried in fine sandy soil to a depth of 10 cm. The half lethal temperature (T50) was 54°C in wet soil and 77°C in dry soil. Microwave heating was much more effective in moist soil and soils with higher clay content.

The periodicity of germination in some grass species

New Zealand Journal of Agricultural Research (1961)

G. S. Harris

Summary Periodicity of germination was studied in 26 species of grasses. Considerable variation from species to species was found in rapidity of germination, seasonal periodicity of germination, and length of time during which seed remained viable in the soil. The following are examples of species showing: (a) no dormancy–Hordeum murinum and Echinochloa crus-galli var. frumentacea; (b) some dormancy—Festuca rubra var. commutata and Bromus mollis; and (c) definite dormancy—Agrostis temnuis and Glyceria fluitans. The results are discussed from the viewpoints of: (a) control of weed grasses; and (b) contamination of seed crops by buried viable seeds.

Dermonecrotic factor. I. Nature and properties of a dermonecrotic factor to guinea-pig skin found in human serum.

PubMed (1969)

Alan Ebringer A. E. Doyle G. S. Harris

Serum from hypertensive patients and to a smaller extent from normotensive blood donors contains a factor, which causes necrosis when it is injected into the shaved skin of guinea-pigs. This factor is non-dialysable, and is inactivated by repeated freezing and thawing of serum, by heating to 56°, by precipitation with half saturated ammonium sulphate and by incubation at room temperature with specific anti-serum to human IgG. On separation of serum by Sephadex G-200 dermonecrotic activity is confined to the fraction containing γ-globulins. It is suggested that the dermo necrotic factor found in human serum is a γ-globulin.
