Texas The Chemical Control of Plant Growth . Obtain further 



information about chemical reactions which control plant 

 growth processes as: in vivo and in-vitro biosynthesis of 

 plant growth substances, mechanism of auxin action, nature 

 of interaction of light, auxin, and mineral elements, 

 (especially Zn, Mn, Co, S, K, and Mg) in controlling flower- 

 ing, leaf expansion, elongation growth, dormancy, and seed 

 germination.

Vt. The Mode of Action of Plant Growth Hormones . Study the 



effect of (1) auxin on the metabolism of oats, corn, sunflower 

 and other plants; (2) Giberellin on metabolism of oats, corn, 

 sunflower and other plants. (3) Attempt to formulate a theory 

 on mode of action of these compounds.

Wis. Applications of Plant Growth Substances and Their Mech- 



anism of Action . To amplify present applications, develop new 

 uses for plant growth substances, determine manner in which 

 they exert their effects, and investigate their use in con- 

 trolling starch production of peas and their influence on 

 protein content of field crops.

Wyo. The Use of Growth Modifiers in Production of Alf alf a SeecL 



To (l) screen growth-modifying chemicals for influence on 

 alfalfa seed production. (2) Test promising chemicals as 

 learned under (1) on alfalfa under field conditions to deter- 

 mine practical recommendations.

Environmental Factors 



Ariz. Factors Affecting the Production of Citrus in Arizona . 



To study (1) rootstock effects and nursery management, (2) 

 adaptation of new varieties and strains, (3) soil management 

 in relation to nutrition, (U) nutritional and growth stimulating 

 sprays, (f>) citrus irrigation, and (6) low temperature effects, 

 surveys, grove heating.

Ariz. Influence of Climatic Factors on Fiber Properties in Cotton , 



To learn (1) if differences occur in fiber properties of same 

 variety of cotton grown in various climatic areas of state, (2) 

 if climatic factor or factors which may influence fiber prop- 

 erty variation between areas as well as year to year variation 

 at same time.
