   Notes: Results of the analysis for each species is given individually. Degrees of freedom is given first for the source and then for the total. Percentage explained is the percentage of the total deviance explained by each variable.

*P < 0.05, ** P < 0.01, ***P < 0.0005

   Notes:  Percentage explained is the percentage of the total variation (sum of squares) explained by each effect. P < 0.0005 for all effects except seed type × trial, which was not significant (P > 0.3).
