Temperature Effects On Germination Characteristics And Traffic Tolerance Of Newly Established Stands Of Nineteen Commercially Available Cultivars Of Seeded Bermudagrass, Michael Todd Deaton Jan 2012

Temperature Effects On Germination Characteristics And Traffic Tolerance Of Newly Established Stands Of Nineteen Commercially Available Cultivars Of Seeded Bermudagrass, Michael Todd Deaton

Theses and Dissertations--Plant and Soil Sciences

Nineteen bermudagrass (Cynodon dactylon (L.) Pers.) cultivars were evaluated for field emergence, establishment rate, traffic tolerance, post-harvest seed coating, germination velocity, and total germination under varying temperature regimes. Two cultivars were evaluated for thermal modeling, day/night temperature fluctuations, day lengths, and effects of fluridone on speed and percentage of total germination.

The effect of cultivar was highly significant for visible field germination, time to 100% cover, and traffic tolerance in both 2010 and 2011. Riviera was the slowest or equivalent to the slowest for visible germination. Casino Royale was the fastest or equivalent to the fastest for visible germination. …
