<Jis • Relationship of Plant Nutrition to Disease Incidence 



and Expression of Symptoms , To learn influence of various 

 (1) plant nutrient ratios and levels on visual expression of 

 certain potato virus and other diseases, (2) nutrient ratios 

 and levels on plant, susceptibility to diseases and their 

 effect on yields, (3) nutrient ratios and levels on behavior 

 of virus in plant, measured quantitatively, (U) potato virus 

 diseases on nutrient uptake by plant.

111. The Occurrence and Activity of Glycolytic Enzymes in Corn . 



To (1) determine if glycolytic enzyme system can be detected in 

 corn seeds and seedlings using methods which have been shown 

 adequate with other plants; (2) determine presence and degree 

 of activity of glycolytic enzyme system in various inbred lines 

 and hybrids of corn; and (3) isolate and characterize specific 

 enzymes such as aldolase and triose phosphate dehydrogenase 

 which play key roles in this metabolic system.

 stover and grain per plant of corn at different rates of 

 planting, (2) relation of CO2 content of air to composition 

 and to yield of stover and grain per plant of corn at differ- 

 ent rates of planting, (3) metabolism of corn plant and its
