Calif. Etiology of Storage and Transportation Diseases of Fresh 

 Fruit and Vegetables and Their Depressing Influence on Market 

 Values . To (l) learn cause of different types of disorders of 

 fresh fruit and vegetables in storage, and transportation! (2) 

 learn factors favoring occurrence of these disorders; (3) devise 

 ways and means of overcoming the inception and development of these 

 disorders; (A) influence producers, storage operators, and trans- 

 portation agencies to initiate improved operations by showing 

 depressing effects of these disorders on market values.

Hawaii Studies on Post-Harvest Physiology of Hawaiian-Grown Fruits, 

 Vegetables and Ornamentals as Applied to Quality, Storage Life 

 and Marketability . Investigate basic requirements of harvesting, 

 transporting, handling, and storage necessary to assure high 

 quality and marketability of various plant commodities from various 

 areas.

The Oxidative Enzyme Systems of Fungi in Relation to Their 

 Plant Parasitism and Their Sensitivity of Fungicides . To (1) 

 Evaluate methods of determining activity of several oxidative 

 enzyme systems in fungus tissue; (2) determine existence and 

 distribution of oxidative enzyme systems in variety of fungi; 

 (3) determine sensitivity of all systems studied to different 

 types of fungicides; (4) determine, by use of inhibitors, 

 necessity of certain systems in metabolism of fungi known to 

 be relatively tolerant to some fungicides; and (5) investigate 

 oxidative enzyme systems of host and parasite in specific cases 

 that seem to complement each other in host-parasite interaction.

The Physiology of Phytopathogenic Fungi . To gain better 

 understanding of physiology of fungi in relation to plant disease 

 along these lines; (l) nutritional needs of fungi in culture and 

 in the host; (2) physiological basis of variation in pathogenicity 

 and specialization in fungi; (3) nature and physiological action 

 of metabolic products of fungi, and (4) mechanism of fungicide 

 action.

Physiology of Parasitism by Plant Pathogens . To determine 

 characteristics and mechanisms which enable certain bacteria and 

 fungi to live as parasites of higher plants, hoping to find points 

 of attack that can be used in more effective control.
