Conn. Genetic, Cytological, and Biochemical Studies on Cytoplasmic 

 Differences in Plants . To study (1) mechanism responsible for 

 cytoplasmic pollen abortion in maize through genetic, biochemical, 

 and cytological techniques; (2) extent and nature of gene-ctyo- 

 plasmic interactions, and their role in differentiation and 

 speciation. 



PI. Path., Ent., Biochem. 507 



Fla. Plant Improvement With Gamma Radiation . Study techniques 



of plant irradiation with gamma radiation and their application 

 to various plant species (l) to achieve the highest possible 

 efficiency in artificial induction of genetic variability and 

 (2) to increase range of genetic variability as source material 

 for varietal improvement.

N. Y. A Taxonomic Study of the Members of the Solanaceae, 

 (Cornell) Scrophulariaceae. Verbenaceae. Boraginaceae. Nolanaceae . To 



determine genera, species, and named varieties of above families 

 that are currently cultivated in U. S.; (2) determine correct 

 identity and nomenclature of domesticially cultivated com- 

 ponents; (3) devise techniques and devices by which horticul- 

 turists may identify cultivated members of the families; and (A) 

 provide growers and distributors with information from this study 

 as pertains to misidentifications and correct identifications of 

 materials known to be grown or distributed under erroneous names.

N. Y. Taxonomic Study of the Cultivated Members of Sixteen 

 (Cornell) Families of Economic Plants . (1) Learn genera, species, and 

 named variants of above families now cultivated in U. S.; (2) 

 learn correct identity and nomencalture of domestically cultivated 

 components; (3) devise techniques and devices horticulturists can 

 use to identify members of these families; (4) provide growers 

 and distributors with data from study as pertains to misidenti- 

 fications and correct identifications of material known to be 

 grown or distributed under erroneous names. 

 Hortorium 70 



N.Y. Windbreaks for Muck Land at Elba. New York . To determine 

 (Cornell) if the presently used willow, Salix purpurea . can be successfully 

 grown for windbreaks, when properly managed and disease free 

 stock is used, and if the attempt is not successful, to find a 

 substitute.
