CONN S 43 no.93« WmmMS'l,:^'>l>^iv PLEASE HANDLE WITH CARE University of Connecticut Libraries Bulletin 939 October 1996 Seed Germination and Purity Analysis 1996 no.13^ BY SHARON M. DOUGLAS Official samples of 351 vegetable and 15 lawn seed were collected by inspectors from the Bureau of Regulation and Inspection of the Connecticut Department of Agriculture for testing in 1996. As the official 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 12 companies. Results are presented by plant type, variety, germination found, germination standard, and compliance with the standard. Germination standards are set by the Federal Seed Act. The categories for label compliance are: 1) seeds meet label claims for germination and 2) seeds do not meet label claims for germination within allowable tolerance. All tests were replicated twice. In addition, seedlings 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 351 vegetable seeds tested, five did not meet their claims for germination. These were not retested because of insufficient numbers of seeds. Seed samples 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 total number of samples tested and the percentage of claims in each compliance category for each type of vegetable. Table 4 shows the results of purity and germination tests for individual lawoi 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 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. Four of the 15 lavra seed samples tested met label claims for both purity and germination. Four samples did not meet claims for purity, five samples did not meet claims for germination, and two samples failed label claims for both germination and purity. In addition to germination and purity tests, label claims for the percentages of inert matter, crop seed (other than lavra seed), weed seed, and the presence of noxious weeds were also evaluated. All samples met label claims for these criteria. Analyses were performed by Mary K. Inman and Dr. Sharon M. Douglas. Samples were collected by Alton Van Dyke, Seed Control Official. The Seed Law is administered by the Seed Control Official for the Commissioner of the Department of Agriculture. Sharon M. Douglas Table 1. Germination of vegetable seeds.
