PLANT PHYSIOLOGY AND NUTRITION 



General 



Ala. Relationship of the Microflora to Deterioration of 



Stored Seed , To learn (1) effects of seed moisture content , 

 storage temperature and aeration on growth of various species 

 comprising microflora of stored seed, (2) relationship be- 

 tween activity of microflora and deteriorative changes in 

 stored seed, and (3) effect of microfloral inhibitors on 

 microbial growth and bioprocesses of seed.

Ariz. Pollen Substitute for Honeybees . To produce an econom- 



ical substitute for pollen fraction of diet of honeybees. 

 Biochem. 382 



Ark. A Study of Factors Affecting the Fruiting Behavior of 



Cotton . To investigate factors affecting fruiting habits of 

 cotton: initiation, intensity, fruiting pattern, cutout, etc., 

 (2) use obtained information to tailor growth of plant that 

 maximum yields may be secured from available soil and climatic 

 resources.

111. A Study of Various Factors Affecting the Thermal Resist- 



ance of" Bacterial Endospores . To evaluate and determine con- 

 ditions which affect the thermal resistance of bacterial en- 

 dospores with particular emphasis on endospores produced by 

 bacteria of importance in spoilage of thermally produced foods.

Ind. The Effect of Fungus Products on Plants , (l) Search 



among products of micro-organisms for compounds affecting 

 dormancy, growth and disease development in plants. (2) 

 Learn mode of action and properties of compounds possessing 

 such characteristics. (3) Develop techniques for applica- 

 tion of useful compounds discovered.

Kans. Physiological Studies on Crop Plants . To (1) determine 



role of wheat awn, particularly its relation to yield, test 

 weight, and kernel weight ; (2) study physiological factors 

 influencing development of chlorosis in sorghums; and (3) 

 develop or adapt chemical tests for tissue viability in 

 wheat plants subjected to temperature extremes; also com- 

 parable test for protoplasmic differences which may exist 

 between drought resistant and susceptible lines of wheat.
