Effect of Soil Temperature on the Reproductive Processes of Kentucky Bluegrass (Poa pratensis L. ‘Newport’)1
- M. A. Maun,

- C. L. Canode2
Kentucky bluegrass plants grown in pots for 38 weeks under field conditions were subjected to soil temperatures of 14 ± 0.5 and 22 ± 2 C in a greenhouse environment. A soil temperature of 22 C significantly increased culm height, number of spikelets per head, percentage fertility of florets, and seed production. The 22 C soil temperature also resulted in a 5- to 8-day earlier maturity of panicles compared to the 14 C soil temperature. There was no significant difference in number of heads per plant between the two temperatures.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
