Fungus Diseases 



Calif. Pectic Enzymes of Fungi . To determine role of yeasts and other 

 fungi in hydrolytic breakdown of pectic substances, surveying rep- 

 resentative species of yeasts as to their ability to form enzymes 

 capable of causing degradation of pectic substances, and when enzyme 

 activity is formed, investigate the mechanism of its actions on 

 pectic substances. 

 Food. Tech. 1522 



Ga. Taxonomy of the Genus Helminthosporium. — 1. Classification 



of the Graminicolous Species of Helminthosporium . To review 

 the classification of species of Helminthosporium occurring on 

 grasses and cereals. 

 PI. Path. 97 



Idaho The Biology of Sclerotinia Sclerotiorum (Lib.) Massee . To 

 determine (1) if strains of this organism exist in Idaho; (2) 

 growth, cultural characteristics and varietal susceptibility of 

 Sclerotinia sclerotiorum in Idaho vegetable growing areas; (3) 

 factors in development of sexual stage of organism and if there 

 are different sexual strains of the organism; (4) relative 

 importance of sexual spores in dissemination of organism and 

 spread of disease in Idaho; (5) effect of crop residues on formation 

 and survival of sclerotia in soils. 

 PI. Path. 205 



Ind. The Effect of Fungus Products on Plants . (1) 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 application of useful compounds discovered.

Kans. Mycological Investigations of Parasitic Fungi . To (l) identify 

 and determine distribution of parasitic fungi of agronomic and 

 horticultural crops in Kansas; (2) study life histories of parasitic 

 fungi relative to their control; (3) study nature of resistance of 

 economic crops to diseases; (4) study fungous and bacterial 

 parasites of fungi causing rust, smut, and other diseases of economic 

 importance; and (5) determine number, type, and time of appearance 

 of spores in the air. 

 Bot., PI. Path. 266 



N. T. Genetic Experiments on Primitive Organisms, Designed Specifically 

 (Cornell) to Obtain Information on Inheritance Models , In order to advance 

 the genetical and statistical theory of quantitative inheritance, 

 specific experiments need to be planned, conducted, and analyzed and 

 application of statistical procedures needs to be made on actual 

 data from a genetic experiment.
