In all other lots, both treated and untreated, the total percentages germi- nated after 21 days are not much larger than after the first five days. As is seen in Table 3, many of the seeds that did not receive acid treat- ment failed to germinate after 21 days
. Annual report of the New York State College of Agriculture at Cornell University and the Agricultural Experiment Station. New York State College of Agriculture; Cornell University. Agricultural Experiment Station; Agriculture -- New York (State). 304 Bulletin 312 untreated seed after the same time showed an average of only 48 per cent. In all other lots, both treated and untreated, the total percentages germi- nated after 21 days are not much larger than after the first five days. As is seen in Table 3, many of the seeds that did not receive acid treat- ment failed to germinate after 21 days between moist blotters. On examination, a few of these non-germinated seeds were found to be dead, being soft and somewhat decayed. Most of the non-germinated seeds, however, were bright in color, and the seed coats were hard and firm. Practically all of these bright-colored seeds were really alive, as ^was. Fig. 81—Red clover seed I-5-5. One hundred seeds of red clover treated with concen- trated sulfuric acid for 60 minutes. Ninety-one per cent germinated after 5 days. Nine " hard seeds " remain shown by the subsequent tests given them. In order to further test these hard, bright-colored seeds, they were taken from between the moist blotters and treated at once with concentrated sulfuric acid for 30 or 60 minutes, after which they were thoroughly washed and again placed in the germinator between moist blotters. The number of seeds from each lot thus treated is shown in Table 4, in the column " Number of ; Thus, from the lot in Table 3 marked I-i-i, 72 seeds were taken for the further treatment shown in Table 4. These 72 seeds, as indicated in Table 4, had received the " previous treatment " of being soaked in water 2 hours and remaining between moist blotters in the germinator for 21 days. After treatment with concen-. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readabili
