Dr. Link had found a plant hormone called heteroauxin, previously found elsewhere, in the nodules of red kidney beans. When applied to the bean roots, a paste containing the hormone caused bending, coiling, vertical retardation of root growth, lateral acceleration of root growth, local increase in thickness of the root...
...billionth of a gram of hormone. No subject has excited plant physiologists more than this in the past decade, and it has seen its major development in the last five years. Yet it was foreshadowed a half century ago by Julius von Sachs, a brilliant German who reasoned that roots and flowers must be produced by special chemical substances, root-forming and flower-forming, elaborated in plant tissue. The foundations of the science were laid about 1910 by Fitting of Germany, and by Boysen Jensen of Denmark. The latter cut off the tip of the leafsheaves in young oats. This...
...this instance, the lag of commercial exploitation behind laboratory research was remarkably short. Indolebutyric acid, one of the Boyce Thompson stimulants, has already been placed on the market by several manufacturers as a root stimulator for cuttings. Merck Chemical Co. sells it as "Hormodin A" at a price of $2 for 15 cubic centimetres, which, diluted upwards of 6,000 times, is enough for about 1,500 cuttings. Pennsylvania Chemical Corp. markets it under the name of "Auxilin" at a price of $1 per half ounce. The prospect is that in ten years the nurseryman who neglects to stimulate...
About the current state of the New York Stock Market, whose six-week decline has been attributed by many to thinness of trading brought on by SEC regulation, Chairman Douglas dropped several broad hints: "From time to time we hope to be able to get at the root of market trends. If it is natural, economic forces, that is one thing. If it is artificially caused, that is something else. You should remember that we are not interested in prices as such. . . . We want a free market, and prices will always go up & down in a free market, depending upon...
...drop in metals pretty well completed the deflation of last spring's commodity boom, the root of current business troubles. Cash wheat was down from $1.60 to $1.23 per bu.; corn from $1.58 to $1.21 per bu. ; cotton from 15¼? to 8½? per lb.; rubber from 27? to 17¼ per lb.; steel scrap from $23.50 to $18 per ton; cocoa from 13? to 7? per lb.; turpentine from...
