~ ^First year height adjusted for seed weight and germination time effects. ~ 

 ^Third year height adjusted for first year height differences. 



^Only 2 replicates were used for cotyledon number and length analyses so degrees of freedom for replicate and 

 error were adjusted accordingly. 



"** and ** indicate significance at the 5 percent or 1 percent level, respectively. For detailed analyses of 

 variance see Appendix Table 15. 



^Includes all interaction terms involving replication. 



^Pooled estimate from 30 to 50 plots with 5 to 10 seedlings per plot.
