Page 364 - the warranted conclusion, drawn from tests of two seasons (1901 and 1902) with formalin and the extended work of many seasons at the Station with corrosive sublimate appears to be that corrosive sublimate seed treatment does not prevent the Rhizoctonia disease to any appreciable extent, while the formalin seed treatment, as shown conspicuously by study of the growing plants and usually in the yields of tubers, does prevent the disease to a very marked extent.
Page 143 - The trees were three years old. The galls varied in size from one to two inches in diameter and were located mostly on the tap-root, but in a few cases on lateral roots. Some of the trees had several galls each. We believe the galls were typical of those commonly found on apple trees in New York nurseries. Five of the trees were dug in 1903, five in 1905 and the remainder in 1907. In no instance was there any evidence that the galls had increased in size or number, or that they had been in any way...

Page 143 - Newark, NY, set out an experimental orchard of 500 trees, mostly Baldwins, all affected with crown gall. The trees have now been set nine years. Under date of January 20, 1908, Mr. Stuart writes as follows: "These trees, to-day, show as good a growth as the trees planted the same time and free from crown ga51. The bark is smooth, healthy in appearance, and the trees look thrifty and vigorous.
Page 249 - ... heavy frosts there was an increase in the proportion of small transparent colonies. Potted soils did not show this increase even when enriched with sugars. In fact the enriched soils showed fewer organisms in the frozen than in the unfrozen samples. Harder concludes that the increase in numbers was due to mechanical transportation by moisture coming up from below during heavy frosts. Conn (1918), in his microscopic study of bacteria and soil fungi, found that there was more or less clumping of...

Page 64 - The samples were all taken from one small plot in the center of the area grown for soiling and the results of the analyses are expressed as percentages of the total dry matter present. TABLE VI. — Composition of dry matter of Sudan grass at various stages of growth As the moisture decreases and the dry matter content increases in the later stages of growth of Sudan grass, a few minor changes take place in the relative proportions of the individual constituents of the dry matter. In the earlier...
