Vegetables & Dry Bean Seed Testing

SGS has extensive experience in testing sweetcorn, cucumber, watermelon, and garden beans in Kimpak-based sand emergence tests. We also test onions, carrots, Brassica spp., beets and numerous other vegetable species. Our flower seed experience includes marigold, petunias, zinnias and a number of other annual and perennial species. See "Native Species" for more information on wild flowers.

• Mechanical Purity and All-States Noxious Weed Examinations
• Standard Germination Tests
• Sand Emergence Test

		Mechanical Purity and All-States Noxious Weed Examinations Mechanical Purity and All-States Noxious Weed Examinations are conducted in accordance with the Association of Official Seed Analysts (AOSA) "Rules for Testing Seeds". The All-states noxious weed examination includes all states except Hawaii. Submit a representative sample for these tests.

Standard Germination Tests
Standard Germination Tests are conducted on a 400 seed sample and seedlings are evaluated in accordance with the Association of Official Seed Analysts "Rules for Testing Seeds". When we observe low germination due to ungerminated seeds, we check their viability using the tetrazolium test. We also identify fungal species and abnormalities to help explain the cause for lower viability. Sand emergence tests are available.

		Sand Emergence Test Sand Emergence Test  is conducted similar to a standard germination test with the addition of one inch of sand over the paper media. Sweetcorn, peas, and garden beans are routinely tested with sand. Sand tends to suppress fungal development and facilitates uniform water uptake.
