A Rapid Serological Bean Blight Test And Antibiotic Control Measures, Terry Dee Miller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The detection and identification of bacterial pathogens in bean tissues can be accomplished with relative ease and certainty by utilizing antiserum prepared against specific bean pathogens. This test requires only fifteen minutes to complete, and a minimum amount of equipment. In addition to speed and ease, it eliminates the difficult process of isolating the bacterial pathogens from the many contaminants that will grow in nutrient culture techniques. The advantage of this technique is primarily based on the utilization of the bacterial population already present in the diseased plant tissues.

The effectiveness of this method has been demonstrated by diagnosing beans …

The Role Of Stomata In Gaseous Fluoride Injury To Plants And Several Enzymatic Changes Associated With That Injury, Bachettira Wthappa Poovaiah

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect of fluoride fumigation on water relations and several enzymes of Glycine max and Pelargonium zonale plants were studied.

Glycine Max leaves absorbed 600 parts per million fluoride from an atmosphere of 15 parts per billion fluoride during 96 hours fumigation. Lower, fully expanded leaves were always more severely damaged than the upper younger leaves. In day versus night fumigation experiments, although daytime fumigated plants absorbed less fluoride than continuously fumigated plants, they had two to three times more fluoride than the nighttime fumigated ones and also exhibited more severe damage.

Transpiration of fumigated plants decreased markedly, presumably due …

Survey Of The Matric Potential Of Various Plant Groups, Hussain Ali Al-Saadi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Matric potentials of leaves or photosynthetic stem tissues from sixty species, including hydrophytes, xerophytes, and halophytes, were measured by the pressure membrane apparatus. The matric potentials of different families and other plant groupings were compared; the correlation between matric potentials and other properties, such as estimated drought and salt tolerance, tissue moisture content, and mineral ion composition were also determined.

High matrix potential values and tissue moisture content were measured in species of Chenopodiaceae, considered more salt and drought tolerant than species in other families.

Low matric potential values were found in the coniferous tree leaves, which also have low …

Flowering Plants: Lilies To Orchids, Robert H. Mohlenbrock

Illustrated Flora of Illinois

A continuation of “The Illustrated Flora of Illinois” series, this volume features Illinois flowering plants. This series is designed to provide a working reference for the identification and classification of all the plant forms found in the state. This series is the first of its kind, as no other study of this sort has been undertaken in any other state, and as such, is an unparalleled contribution to its field.

In his introduction to this volume, Mr. Mohlenbrock discusses some of the terms and procedures used in the identification and classification of the plants. He outlines the life histories and …

The Western Australian Herbarium, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

The new Western Australian Herbarium building opened on March 5, 1970, provides for the first time, ideal storage conditions for the State's priceless collection of plants, and adequate facilities for botanists to study them.

The unique character of Western Australia's flora has attracted world-wide interest and the State needed a single herbarium recognised by the herbaria of the world.
