Fig. 5. Length of white clover primary stolons and stolon branches in 1997 and 1998 at three locations in Pennsylvania in response to plant spacing. Data points are averages of two orchardgrass cultivars and three replications with two radii per replicate. There were no differences (P < 0.05) in slopes (b values) among locations in 1997. The slopes for the response of main stolons and first- and second-order branches at Rock Springs differed from those of Port Matilda and Kylertown in 1998. Asterisks indicate that slopes are different (P < 0.05) than zero.
