Abstract/Contents:"Kentucky bluegrass (Poa prantesis L.) is the most widely used cool-season turfgrass in athletic fields, but it is slow to germinate from seed. The objective of this experiment was to determine the germination rate among several Kentucky bluegrass cultivars. Twenty-one cultivars or genotypes were tested with seed stored at 4°C for >2 weeks prior to germination tests. Standard germination tests using blotter paper, petri dishes, and a seed incubator set at alternating 25/15°C (day/night) temperatures and an 8 h d-1 photoperiod were used for the test, consistent with the recommendations of the Association of Official Seed Analysts. The germination test lasted 28 d, and the blotter paper was moistened with a 0.2% KNO3 solution as needed every 2-3 d. Each cultivar was tested with four replications and two separate seed lots. Germination was most rapid among the experimental genotype PST-T15-44 and the commercial cultivar After Midnight, as they took the fewest days to reach 50% germination in only 7.9 or 8.8 d, respectively. Cultivars Tirem and Volt required >12 d in both runs to reach 50% germination (12.0 to 13.7 d). These results point to a 5 d to 6 d difference in germination, depending on the cultivar a turf manager selects. By identifying rapidly germinating cultivars, it may be possible for athletic field managers to repair damaged turf areas more quickly in between events."
