ANNUAL REPORT, 1941 7^ 



solutions, Hormodin A at 30, 45, 60, 75 BTI units, indolebutyric, indoleacetic, 

 and naphthalencacetic acids at concentrations of 10, 15, 20, 25, 30, 35, 40, 45, 50, 

 and 60 mg./lOO c. c, Roche No. 202 at unit concentrations of 25, 50, 75, 100, 

 125, 150, 175, 200; and an untreated lot. Each immersion treatment was con- 

 tinued for 16, 24, and 40 hours. 



A series of fifteen cuttings to the lot was taken in February and run in sand 

 and sand-peat at a constant temperature of 65° F. Treatments were Hormodin A 

 at 90, 105, and 120 BTI units, with additional test treatments of indolebutyric 

 acid. Results were slightly better from the sand-peat medium than from the 

 sand, and from a higher temperature of the rooting medium. Highest rooting 

 percentage was 80 with indolebutyric acid at 40 mg./lOO c. c. for 24 hours at 

 65° F. in sand-peat. Immersion treatments for 24 hours with Hormodin A at 90 

 BTI units (in sand) and at 120 BTI units (in sand-peat) gave 66 percent rooting; 

 and at 90 BTI units (in sand-peat) 65 percent rooting at 60° F. In the un- 

 treated lots a single 13 percent rooting occurred at 65° F. in the sand-peat 

 medium. Rooting from other lots was negligible.

Variety Studies. (W. H. Lachman and G. B. Snyder.) These studies are con- 

 ducted each year to ascertain the adaptability and general usefulness of the 

 newer introductions in comparison with the standard vegetable varieties. The 

 weather conditions at Aniherst during the summer of 1941 were very near to the 

 average for the last 50 years and were ideal for proper growth and development. 



Especially noteworthy was the new "Summer Pascal" celery which produced 

 a medium large plant weighing a little over two pounds and measuring about 

 20 inches in height. This variety produced a crisp, succulent stalk with an ex- 

 cellent nutlike flavor. 



There were 62 strains and varieties of tomatoes included in the trials. Particu- 

 larly outstanding were "Stokesdale," an early mid-season variety which yielded 

 well and had good shape and size, and "Rutgers," a late, high-yielding, very 

 attractive tomato which is especially valuable for canning. The varieties "Vic- 

 tor" and "Bounty" which are earlj' varieties proved a little disappointing because 

 of poor fruit color and sparseness of foliage. "Pan American," a new introduction 

 of the U. S. D. A., is reported to be highly resistant to fusarium wilt. This 

 variety has excellent foliage, but from the experience gained by limited trial, 

 large plantings are not suggested because of only a moderate yield and variable 

 fruit shape and size when grown either pruned and trained or unpruned and 

 untrained. 



During the summer, eight varieties of tomatoes were tested for vitamin C, 

 with the following results:
