Аннотация: The book deals with the methods of soil analysis. The methods are of importance to pepople working with soils and frequently are needed by them. The book appeals also the principles of the method, comments on such matters as limitations, pitfalls and precision and reference to sources in the literature to which readers might go for further study.

Аннотация: Pinus strobus or P. resinosa seedlings, 2 or 3 years old, were illuminated in a closed chamber for 1 hour in the presence of C14O2. This was followed by various periods up to 24 hours under different conditions of light and darkness. Then each seedling was divided into its shoot, stem, and roots, and these were extracted separately with 80% ethanol. The extracts were resolved first on resins into sugar, amino acid, and organic acid fractions and then resolved further by paper chromatography. The C14 content of various fractions and the eluted compounds was determined by plating and counting their aliquots. Ethanol-insoluble residue was oxidized and counted as BaC14O3. 8 hours after administration of the C14O2, 91 to 94% of the total C 14 was found in the ethanol-soluble fractions of shoot, stem, or root. In the shoots sugars were found to represent more than 95% of the ethanol-soluble photosynthate, with sucrose forming three-quarters of it. In stem and roots sucrose represented from 75 to 94% of the translocated photosynthate. Raffinose, glucose, and fructose were present in both stem and root.

Аннотация: The paper deals with the results of the present investigation: bark extracts from hybrid aspen and its parent species contained different sugars; if the fungus will, on the whole, establish and develop an attack inside the host, the capacity of utilizing the present sources of energy may be decisive; in experiments in vitro the effect of sucrose as a source of energy has been studied

Аннотация: Aged seeds of Scots pine left different eluate spots on the blotter in a germinator after about 24 hours' incubation. Fresh seeds do not give off such eluates. Among the leached substances were found proteins, nucleic acids, amino acids, fats, sugars, etc. The eluate spot are visible on the blotter only after development by simple biochemical methods used in paper chromatography. Possibility of using this eluate-development method as a seed viability test, and other practical aspects, are described.
