Anthracnose Kernel Rot Of Maize Caused By Colletotrichum Graminicola (Ces.) Wils.: Mode Of Entrance Into And Disease Progression In Ears, Claude Nankam, D. C. Foley

Journal of the Iowa Academy of Science: JIAS

The mode of establishment of Colletotrichum graminicola in maize ears to cause kernel infection was studied for two types of infective propagules and three sites of penetration. Shank inoculations with either oat-grain inoculum or spores induced a greater percentage of infected kernels than inoculations of the husk or kernel area with an infected oat grain or inoculations of the silks with an oat grain or a spore suspension in 1985. But in 1986, a spore suspension in the kernels ranked first among all the treatments based on the basis of disease severity on the kernels. However, a large percentage of …

The Taxonomy And Biology Of Strauzia (Diptera: Tephritidae), W. Bryan Stoltzfus

Journal of the Iowa Academy of Science: JIAS

The North American genus Strauzia is revised. Five new species are included with keys to adults of the 12 known species. Host plant, important larval characteristics, and life cycle information are given for 11 of the species. The evolution of the genus is discussed and 14 host plants are reported. All species bore in the stems of Asteraceae, pupariate in the crown area or in the soil, and are univoltine.

Catalogue Of The Living Collection Of The Iowa State University Botany Department Greenhouses, Richard W. Pohl, Deborah Q. Lewis

Journal of the Iowa Academy of Science: JIAS

The Botany Department greenhouses at Iowa State University are a rooftop facility including 17 separate houses, divided into three temperature zones. Some illuminated houses are provided to encourage good plant growth during the winter. One greenhouse is operated as a short-day facility and provided with curtained chambers for short days. Summer cooling of the greenhouses is effected by evaporative coolers.

The living teaching and research collections include over 800 plane taxa, ranging from bryophytes to orchids and composites. Propagation materials, as available, may be provided to other educational institutions for teaching or research.

Annual Report Of The Iowa Academy Of Science, 1987-88, James G. Macmillan

Journal of the Iowa Academy of Science: JIAS

Since 1975 when a history of the Iowa Academy of Science was written for the centennial of the founding of the Academy, an Annual Report has acted as a continuing record of the Academy’s activities.

This report encompasses the year beginning July I, 1987 to June 30, 1988 and is based on minutes of committee meetings, Board minutes and recollections of the author. Each part represents a major activity of the Academy.

An Industry Perspective On The Benefits Of And Regulation Of Genetically Engineered Plants, Nicholas M. Frey

Journal of the Iowa Academy of Science: JIAS

The seed industry has routinely incorporated new technology into its research and development programs. Plant generic engineering is the most recent technology to be utilized for seed product development efforts. New sources of herbicide, insect, and disease resistance are being incorporated into crop plants using cellular and molecular biology techniques.

New regulatory guidelines have been developed which require regulatory approval before genetically engineered plants can be reseed in the field and ultimately marketed. The impact of these regulations on product development is unclear. Hopefully a dialogue will develop among industry, government agencies, and the public such that reasonable and appropriate …

Agronomic Performance Of Sorghum Hybrids Produced By Using Different Male-Sterility-Inducing Cytoplasms, A. J. Maves, R. E. Atkins

Journal of the Iowa Academy of Science: JIAS

Experiments were conducted in three environments in Iowa to obtain information on the effects of different cytoplasms on agronomic characters in grain sorghum (Sorghum bicolor L. Moench) hybrids. Compared with A1 cytoplasm, A2 and A3 cytoplasms delayed flowering; reduced the percentage of fertile pollen, the number of seeds per panicle, and grain yield; and increased 100-seed weight of the hybrids. Hybrids with A2 or A3 cytoplasm did not differ (p ≥0.05) from those in the A1 cytoplasm for plant height, panicles per plant, or for length, width, and area of the third and fourth leaves from the top of …

A Vascular Flora Of The Swaledale Railroad Prairie In North Central Iowa, Thomas L. Eddy

Journal of the Iowa Academy of Science: JIAS

"Railroad prairies" are remnant native grasslands that grow along railroad right-of-ways. The Swaledale railroad prairie, which is in north central Iowa, occurs along the Chicago and Northwestern Railroad Company right-of-way in Cerro Gordo County.

The railroad right-of-way and an abandoned sand pit, which lies adjacent to the railroad embankment, harbor a collection of tallgrass prairie remnants. The sand pit supplied earthen fill which was used to elevate the original railroad embankment, circa 1887. It is noteworthy that the method of excavation for fill material helped to preserve earthen knolls that are covered with original tallgrass prairie.

Plant collections were acquired …

A New Name For A Continuing Publication, Marilyn D. Bachmann, Roger W. Bachmann

Journal of the Iowa Academy of Science: JIAS

With this issue, the former Proceedings of the Iowa Academy of Science becomes The Journal of the Iowa Academy of Science, a change which coincides with the l00th annual meeting of the Academy. This concludes a process started in 1971 when the Proceedings became a quarterly periodical which also included papers that had not been presented at the previous annual meeting.

Impact Of Biotechnology On Agriculture Productivity, Roger A. Kleese

Journal of the Iowa Academy of Science: JIAS

Biotechnology is a diverse array of technologies which today are in various stages of evolution and development. To understand them and the potential application of these technologies to agriculture, it is helpful to consider them in a historical perspective. In addition, it is important to understand the interdependence of biotechnologies on traditional, well developed technologies. The commercial development of biotechnology is more difficult than imagined even as recently as five years ago. Also, the problems being addressed generally demand a much better understanding of the physiology and biochemistry of the plant and animal systems under study. Nonetheless, there is a …

Biotechnology: A Dilemma For Land-Grant Institutions, A. David Kline

Journal of the Iowa Academy of Science: JIAS

There is at least a prima facie moral tension between universities asserting land-grant principles and simultaneously sponsoring biotechnology. The core of the problem is the likely deleterious economic effects of biotechnology on rural communities -- the very constituency whose welfare is supposedly promoted by land-grant institutions. Considered are a number of responses to this tension including efforts to show that the tension is only apparent or that it can be eliminated through various public policies. It is argued that these "solutions" fail.

The upshot is that if the land-grant label is to be taken seriously, those institutions should begin allocating …
