The Optimisation Of Nitrogen Content For Micropropagation Of Eucalyptus Marginata, Andrew James Woodward

Theses : Honours

The use of eucalypts for plantation timber and pulp is becoming increasingly important, as are eucalypts that are resistant to disease and insect herbivory. Where clones with desirable traits have been selected, it is important that these genotypes are preserved. Micropropagation of some eucalypts, and Eucalyptus marginata in particular, can be difficult possibly due to the currently used basal medium of Murashige and Skoog (M&S)(I 962). By examining the nitrogen utilisation and the effects of medium pH of this species, it may be possible to improve general micropropagation protocol. Six clones of the species E. marginata were obtained as shoot …

Population Processes, Kathleen H. Keeler, Anthony Joern

School of Biological Sciences: Faculty Publications

Within the prairies, myriad populations of plants, insects, small mammals, and other organisms form distinct levels of organization. The physical forces of weather and fire and the complex networks of species interactions control each species’s structure and dynamics and determine its abundance or rarity. Variation in population dynamics and interactions over time and space determine the distribution and abundance of species, and ultimately the composition and dynamics of entire prairie communities.

To the casual observer, plant populations on prairies may seem quite static, like museums containing a diverse collection of specimens that can be seen again and again on repeated …

Lichen Use By Larval Leucochrysa Pavida (Neuroptera:Chrysopidae), Penni Jo Wilson

Masters Theses

Leucochrysa pavida is a species of green lacewing (Neuroptera:Chrysopidae) that uses lichen fragments to build a larval debris "packet." The "packet" is eventually used to form a cocoon used during pupation. Only minute lichen fragments are harvested for formation of the packets which makes identification of the actual lichens utilized difficult using morphological characteristics. For this reason, thin-layer chromatography was employed. The thin-layer chromatographic process identifies acetone-soluble lichen chemicals that are formed in lichen thalli. By comparing the chemistry of lichen communities at Tower Rock Recreation Area in Hardin County, Illinois, with the chemicals identified during thin-layer chromatography of larval …

Effects Of Ozone During Soybean Seed Development On Seed Vigor, Karen A. Gerlach

Masters Theses

Soybean (Glycine max L. Merr. cv 'Essex', 'Forrest' and 'Clark') seed were obtained from Dr. Mulchi of the University of Maryland. Seed from 1989 and 1990 were from plants which were exposed to three regimes of ozone during seed development including charcoal-filtered (no ozone), non-filtered (ambient ozone), and non-filtered + 40 n11^-1 O₃. Seed from 1994 were developed with four pollutant regimes of ozone during seed development including charcoal-filtered (no ozone), non-filtered (ambient ozone), non-filtered + 40 n11^-1, and non-filtered + 500 u11^-1 CO₂. The objective of this study was to assess …

Southwest Research-Extension Center Field Day 1995

Kansas Agricultural Experiment Station Research Reports

Each Field Day report consists of individual research reports on topics specific to the region, including cultural methods for most of the major crops grown in Kansas, mitigating the effects of weeds, insects, and disease associated with those crops, and irrigation. Research is conducted and reports written by staff of the K-State Research and Extension Southwest Research Extension Center.
