Relation of Hydrophilic Colloids to Hardiness in Cabbage, Brussels Sprouts, and Alfalfa Plants as Shown by the Dye Adsorption Test

Effect of Lime and Fertility Levels on the Chemical Composition and Winter Survival of Alfalfa1

“…He found that the extent of coagulation varied directly with the decrease in temperature and .inversely with increasing winter hardiness of the plant. Dunn ( 5) found that the content of hydrophylic colloids in the macerated plant tissue, as measured by the dye adsorption test, was to a con- 1 Part of a thesis submitted to the faculty of the University of Wisconsin by the senior author in partial fulfillment of the requirements for the degree of Doctor of Philosophy.

Drought Resistance and Constancy of Osmotic Ascension caused by Wilting in Soybeans

“…Fortunately some of these samples were studied to see the regulation of osmotic value by subjecting them to wilting. Temporary wilting is believed to give the plant drought resistance (16, 42), like the temporary cold resistance (30,31,35,39,40).Whether the experience of former drought, which has influenced to increase the cell sap concentration (6, 7,34,36,43) still effects osmotic ascension or not on the part produced from the growing point after the soil moisture is regained is a problem not yet investigated. …”
