), in Illinois ( Williams, 2015b ) and Pennsylvania ( Sánchez et al., 2005 ). Using 136 edamame entries over a 3-year period, high germination of seed lots failed to account for poor seedling emergence ( Williams, 2015b ). Because of limited research

of plant growth and seed germination ( Petersen et al., 2001 ; Teasdale and Taylorson, 1986 ). Greenhouse and field studies have reported the role of brassica cover crop residues in reducing emergence and growth of weeds ( Al-Khatib et al., 1997

that may affect crop emergence is seed size. Edamame seed mass is ≈30 g/100-seed compared with 15 to 20 g/100-seed for grain-type soybean ( Bernard, 2005 ; Dong et al., 2014 ; Williams, 2015 ). The literature is inconclusive on how seed size affects

germination and seedling emergence. Therefore, temperature may be an important influence factor for germination of litchi seeds. Seed orientation and sowing depth both play important roles in seed germination and seedling emergence ( Aou-ouad et al., 2014

production to obtain optimum seedling emergence and uniformity requires high-quality seeds. Germination tests are used to evaluate the production of normal seedlings under optimal germination conditions ( Atwater, 1978 ; Geneve, 2008 ). However, these do not

Cell trays for raising vegetable seedlings on a large scale have become increasingly popular because of their low cost; however, the method yields poor emergence rates due to the high temperatures when lettuce seeds are sown in the summer

Turfbuilder samples (C and D), the partial coated seed is in the middle and the heavily coated seed is on the right. All seed coating treatments for both turfgrass species were evaluated for emergence in three soil types including the following: 1) a Captina

conditions are near optimum, the standard germination may predict relative seedling emergence potential of the lot in the field. However, field conditions are often suboptimal. Seed vigor is composed of various features of seed quality and is indicative of
