Proposed Physiologic Functions of Boron in Plants Pertinent to Animal and Human Metabolism
(National Institute of Environmental Health Sciences, 1994-11)
Boron has been recognized since 1923 as an essential micronutrient element for higher plants. Over the years, many roles for boron in plants have been proposed, including functions in sugar transport, cell wall synthesis ...
Physiological changes occurring in plant tissue as a result of stimuli administered to break the rest period
(University of Missouri--Columbia, 1914)
It is a matter of common knowledge that most of our woody plants do not grow continuously throughout the year. The fact is brought to our attention especially in spring, when we may observe the awakening of the vegetation ...
Influence of some external conditions upon infection of hosts with powdery mildews
(University of Missouri--Columbia, 1914)
It has long been observed that one condition or another of the environment is favorable to the perpetuation and spread of fungous diseases. For example, it is very easy to recognize the close relation which exists between ...
An experimental study of the rest period of plants : the effect of rest period breaking agencies upon hardwood cuttings
(University of Missouri--Columbia, 1916)
Much work has been done within the past twenty years upon forcing into growth of plants of all kinds, hard wood twigs and pot grown plants, herbaceous perennials, bulbs, tubers, seeds and vegetables by the use of such ...
Some correlation studies in maize
(University of Missouri--Columbia, 1915)
The most common method of selecting seed corn has been for many years to pick the best ears from the crib, no consideration whatever being given to the stalks on which they were borne. Within the last few years, however, ...
A study in the marketing of perishable fruit
(University of Missouri--Columbia, 1915)
The strawberry industry has been a large factor in the development of the Ozark region. Its success is dependent upon the proper solution of a great variety of problems which cannot be solved by the growers, the shipping ...
Chemotropism of fungi
(University of Missouri--Columbia, 1905)
The changing of the direction of growth of fungous hyphae is a complex phenomenon in which at least two factors, cytotropism and hyrotropism, are concerned. Since the complete elimination of neither of these factors is ...
The crown gall disease of the apple : a discussion of the malady in general as applied to Missouri : experiments with the disease
(University of Missouri--Columbia, 1903)
With ever increasing frequency for the past few years attention has been called to the existence of an affection of apple trees known as Crown Gall. This trouble, which is also known as "root gall", consists of galls or ...
Temperature as a factor modifying the toxic action of certain chemicals on the germination and development of a few fungi
(University of Missouri--Columbia, 1905)
The purpose of the experiments, the results of which are presented in this paper, was to determine what might be the modifying effect of temperature on the toxic properties of certain chemicals as shown by the effect of ...
Cytological studies on the zygospores of Sporodinia grandis
(University of Missouri--Columbia, 1912)
In recent years much interest has been aroused in the cytology of the lower fungi, and considerable work has been done upon these forms. While various members of different groups have been studied, the most definite results ...
Bacteria concerned in the making of salt-rising bread.
(University of Missouri--Columbia, 1912)
Salt-rising bread is a kind of leavened bread, which is made light not by the introduction of yeast, as with yeast cakes or by mechanical aeration or by carbon dioxide liberated from chemical compounds, such as baking ...
Physiological studies on Monascus
(University of Missouri--Columbia, 1914)
Moldy silage, because of its economic importance, has attracted considerable attention in the last few years. Certain molds, because of their general and frequent occurrence and peculiar characteristics have become of ...
Conditions modifying the effect of deleterious agents upon the fungi
(University of Missouri--Columbia, 1905)
Nageli, Dandeno and True and Oglevee have drawn the conclusion that the presence of insoluble substances in toxic solutions reduces the toxicity of such solutions. Since in the work already done along this line, phanerogams ...
Some experiments on the toxicity of various chemicals to monilia sitophila (Mont.) Sacc.
(University of Missouri--Columbia, 1911)
The influence of the mineral nutrients upon growth has been the subject of much investigation. It has been found that certain of these are absolutely necessary to all life. Nevertheless, most, if not all, of the chemical ...
Relation of the physical structure of the fruit bud of the peach to hardiness.
(University of Missouri--Columbia, 1912)
The purpose of this research is to determine the relationship of the structure of fruit buds of the peach to hardiness, and, to add to the general knowledge regarding death of plant tissue resulting from exposure to low ...
A study of conformation and the correlation of parts in ears of maize
(University of Missouri--Columbia, 1912)
Volume upon volume has been written and page after page of statistical material has been compiled in regard to the yield of corn, the various varieties, the many soil requirements and the fertilizing problems. Notwithstanding ...
A preliminary list of the rusts of Boone County
(University of Missouri--Columbia, 1913)
A complete list of the rusts of Boone County has not been published. In the year 1889 Dr. B.T. Galloway of the U. S. Department of Agriculture, published a preliminary list of the parasitic fungi of Missouri. The specimens ...
The mechanism of seed dispersal in polygonum virginianum
(University of Missouri--Columbia, 1906)
The achenes of Polygonum Virginianum Linnaeus have a particularly efficient mode of dispersal. The long two-parted styles are persistent and become lignified during the process of development. If, after maturity, these ...
The killing of plant tissue by low temperature
(University of Missouri--Columbia, 1914)
The term freezing to death is applied to a very specific set of phenomena in plants. With all plant tissues, when a certain temperature is reached very shortly after thawing, it will be found that the tissue has taken on ...
Investigation of the rest period of seeds
(University of Missouri--Columbia, 1913)
In all plants, including fungi and algae, as well as higher forms, this periodicity of growth, due to season, nutrition, environment, etc., is seen. Practically all temperate zone plants exhibit a yearly periodicity. The ...
