The University of Connecticut Libraries, Storrs -"* '-' T--T- t t t Q i;i Q n w Connecticut Agricultural Experiment Station, New Haven a Seed Germination and Purity Analysis 1990 BY SHARON M. DOUGLAS Bulletin 884 January 1991 During 1990, official samples of 342 vegetable, 10 lawn grass, and 10 agricultural seed were collected by inspectors from the Marketing Division of the Connecticut Department of Agriculture for testing. As the official state seed-testing laboratory, The Connecticut Agricultural Experiment Station performed germination and purity analyses for compliance with the Connecticut Seed Law Regulations and the Federal Seed Act. Table 1 shows the results of germination tests for individual vegetable seed samples from nine companies. Results are presented by plant type, variety, germination claim, germination found, and compliance with the standards of germination. These standards are set by the Federal Seed Act. The categories for label compliance are: 1) seeds meet label claims for germination within allowable tolerances and 2) seeds do not meet label claims for germination. All tests were replicated twice. If a seed lot failed, it was retested. In addition, seedlings from the seeds must also appear "normal", i.e., they have to be free from decay, have well- developed primary root systems, have well-developed and intact hypocotyls and/or epicotyls, and have healthy cotyledons. Of the 342 vegetable seeds tested, six did not meet their claims for germination. Seeds were also examined for prohibited noxious weed seeds. No vegetable samples contained weed contaminants. The total number of germination claims and the percentage of claims in each category for compliance are summarized for each vegetable seed company in Table 2. Table 3 summarizes the average percent germination claimed, that found, and the standard for each type of vegetable. Table 4 shows the results of purity and germination tests for individual lawn grass seed samples. These are presented by company, brand name and/or seed type or variety mixture. The categories for both purity and germination are as previously described for the vegetable seeds. Lawn seed samples that were labelled with several varieties within a species or with several species within a genus were separated by genus. Purity and germination results are therefore reported as the sum for that genus. The label claim is met as long as this sum equals or exceeds the sum of the individual components for a genus listed on the label. Of the 10 lawn seed samples tested, two did not meet label claims for purity. All samples met label claims for germination. Table 5 shows the results of purity and germination tests for agricultural seed samples. These are presented by company, brand name and/or seed type or variety mixture. The categories for both purity and germination are as previously described. Of the 10 agricultural samples tested, one did not meet its label claim for germination. Six samples met label claims for purity. Four samples were not large enough for purity analysis. In addition to germination and purity tests, label claims for the percentages of inert matter, crop seed (other than lawn grass seed), weed seed, and the presence of noxious weeds were also evaluated. All samples met label claims for these criteria. Analyses were performed by Dr. Sharon M. Douglas and Mary K. Inman. Samples were collected by Raymond Weller and Alton Van Dyke, Seed Control Official. The Seed Law is administered by the Seed Control Official for the Commissioner of the Department of Agriculture.
