Text Appearing Before Image:
; infection in 13 days. - Not presoaked. *Not treated. * Soaking started at 35° 0., and the water was then allowed to come to room temperature; germinationand infection in 8 days. Table 3 shows that the long presoaking period is more desirable.In each case the 15-minute treatments at 54° C. gave the best results,in both seed germination and fungus control. Further tests were made by soaking seed of Honduras rice fromLouisiana at 54° C. for 15 minutes, after presoaking 16 hours and 50minutes in tepid water, and then sowing it along with untreated seedand seed of the same variety which was grown in California. Soilfrom a field where rice had never been grown was placed in large cans(16 by 16 inches and 15 inches deep), and the 50 and 100 seeds weresown in each can. The soil was in excellent condition, so the seedgerminated readily, and none of the seedlings showed signs of blight.Table 4 gives the results of the germination of this seed. Bui. 1116, U. S.
