Fruit Trees . Learn physiological mechanism controlling 

 dormancy of fruit trees. 

 Fruit Crops 877 



111. The Relation of Hormones, Ascorbic Acid, Ascorbic Acid 



Oxidase j and Other Compounds in the Development of Functional 

 fear Shoots of Corn . To (1) determine cytological and bio- 

 chemical processes involved in the development of ear shoots 

 of corn; (2) determine effects of pollination of subsequent 

 biochemical and cytological changes of ear shoots of corn; 

 and (3) investigate nature of growth regulating substances 

 involved in ear and kernel development in corn. 

 Agron. 15-370 



Ind. The Physiology of Flowering and Fruiting of Selected 



Plants" ! To (1) determine nature of physiological processes 

 responsible for flower initiation; (2) determine nature of 

 physiological processes responsible for fruit development; 

 and (3) apply these findings to horticultural crops. 

 Hort. 662 



Ind. Nature and Mode of Action of Some Germination Inhibitors 



Found in Dormant Seeds . Isolate, purify and characterize (1) 

 active antigermination factors from dormant seeds; (2) protein- 

 splitting enzymes susceptible to above factor. (3) Test other 

 proteinase inhibitors to see if antiproteinase activity is 

 capable of inhibiting germination. (U) Test products result- 

 ing from protein-cleavage on dormant or inhibited seeds to see 

 if they can induce germination,

La. Separation and Characterization of Growth Promoting 



Substances in Plant Extracts . Isolate and identify micro- 

 organisms requiring for maximum growth addition of certain 

 plant extracts to a medium containing all known B-vitamins. 

 Study chemical, physical and biological properties of sub- 

 stances. Develop methods of isolation and purification. 

 Identify or characterize isolated f actor (s).

La. Development of Techniques and Evaluation of Chemicals for 



the Defoliation and/or Second-growth Inhibition of Cotton .' 

 (1) Screen and evaluate new chemicals as defoliants and se cond- 

 growth inhibitors, (2) study process of abscission and second- 

 growth inhibition, (3) develop ground spray machines for field 

 application of defoliants and/or second-growth inhibitors, (U) 

 evaluate different nozzles and nozzle arrangements, (5) deter- 

 mine proper spray volume and rate of chemical, and (6) evaluate 

 concept of bottom defoliation as an aid to reducing boll rot.
