Vt. The Role of Boron in Plant Metabolism. (1) To learn a 



specific metabolic function for B in plant nutrition. (2) 

 If a specific site of action can be shown, to use this data 

 to correlate the divergent physiological roles now ascribed 

 to B. 



Agr. Biochem. U£ 



Wash. Metabolism of Germinating Peas . To study nature of re- 



actions which take place during germination of pea seeds, 

 mechanisms by which reactions are controlled, and resulting 

 changes in constituents of plant.

Growth and Growth Regulators 



Calif. Plant Growth Regulators in Relation to the Physiology 



of Citrus . To (1) determine the manner in which mature fruit 

 drop, increased fruit size and increased storage life of 

 citrus may be regulated by the use of plant hormones, in- 

 vestigating effects of plant growth regulators on photo- 

 synthesis, respiration, transpiration, translocation, cell 

 elongation, etc.j (2) evaluate new or partially field-tested 

 materials for their effects on functioning of plants, using 

 lab and greenhouse techniques; and (3) investigate possibility 

 of extending use of plant growth regulators to control of 

 other plant processes, using information developed under (1). 

 PI. Biochem. 13U6 



Calif. The Physiology of Abscission in Horticultural Plants . 



(1) Learn environmental and internal factors affecting auxin 

 gradient at abscission zone. (2) Study associated morphological 

 phenomena. 



Bot. 1357 



Calif. Influence of Plant Regulators on Growth and Fruiting of 

 the Vine * (1) Screen for compounds that effect the vine 

 differently or which produce similar but better responses than 

 those already obtained. (2) Work on elongation of cluster and 

 their branches. (3) Study relation of plant regulators to the 

 carbohydrate nutrition of the vine. 

 Vitic, Enol. 11*21 



Calif. Factors Affecting the Abscission Process in Relation to 

 Defoliation in Cotton . To learn of the physiological factors 

 affecting abscission and to develop more reliable and efficient 

 methods of defoliating cotton.
