Abstract

The use of improved seeded bermudagrasses (SB) has increased. All new cultivars are marketed as coated seed. As germination of many of these new cultivars is less than ideal, questions arise as to the effect coatings have on germination. Five SB cultivars were selected for a series of germination studies. The first study compared coated and uncoated samples of the five cultivars for germination response to six temperature regimes. Overall, commercial seed coating did not affect SB germination. However, both temperature regime and cultivar were significant factors. In a second study, three seed treatments were investigated across three temperature regimes and five SB cultivars to evaluate enhancement of germination. Two of the three treatments improved germination at day 7 indicating increased germination rate. No treatment produced significant results in germination at day 21. Cultivar specific differences regarding treatments were present at all count intervals.
