N. C. Ecological Relationships of Permanent Pasture Plants . To 



(1) determine relative values and adaptations of promising 

 grasses and legumes when grown in associations; (2) determine 

 associative effects of various mixtures on the botanical and 

 chemical composition of the individual species; (3) determine 

 effects of various management systems on the survival, pro- 

 ductivity and chemical composition of certain adapted pasture 

 legumes and grasses; (h) study root interrelationships of cer- 

 tain adapted pasture legumes and grasses; (f>) study moisture 

 requirements of certain adapted pasture legumes and grasses; 

 and (6) determine best method of establishment of permanent 

 pasture mixtures including proper seeding rates, methods and 

 inoculation procedures.

Absorption and Translocation 



Calif. The Physiological Nature of the Processes of Salt Absorp- 

 tion by Roots ; Relations Between Salt Absorption, Accumulation 

 and Translocation^ and the Metabolism of the Plant, Effects of 

 Concentration and Interrelations of Salts, in Nutrient Solution; 

 Effects of Oxygen Supply to Roots and of Temperature of Culture 

 Medium . To study the factors affecting root metabolism in re- 

 lation to solute absorption, and translocation, as a basis for 

 an understanding of crop adaptations to soil and climate, and 

 of the use of soil amendments.

Minn. Movement of Natural Compounds and Agricultural Chemicals in 



PlantsT Its Direction, Modification and Mechanisms . Study (1) 

 rate and direction of movement of plant metabolites from leaves 

 to other plant organs and study effect of stage of plant develop- 

 ment and of certain environmental factors as light and tempera- 

 ture on this movement, (2) movement in plants of chemicals used 

 in agriculture as herbicides and systemic fungicides in relation 

 to normal flow of metabolites, to environmental conditions and 

 to ontogeny of plant.

N. J. Nutrient Ion Absorption — The Study of Ion Absorption and 



Accumulation in Relation to Plant Growth and Quality . To study 

 (1) external and internal factors affecting absorption and 

 utilization of Fe by plants; (2) activity of Fe-containing 

 enzymes in plants in relation to utilization and availability 

 of Fe.
