In addition, fecundity and the collective mass of seeds of a tiller were always tightly correlated: for all years, the correlations between the collective mass of CL seeds and the number of CL seeds were all highly significant ( r 2 from 0.79 to 0.91, all P < 0.0001), as were all correlations between the collective mass of CH seeds and number of CH seeds ( r 2 from 0.82 to 0.95, all P < 0.0001).
