Table 2.
Estimates of mortality rates (with standard errors given in parentheses) per day (log-scale for viability), expected life span, and expected median life span for varied strains (our bd, wild type (WT), FGSC bd, lag-1, lag-1,bd, and bd,ccg-2p:luc (Gooch et al. 2008)) over 9 days. The R2 is the fraction of variation in an ANOVA (see Table1) explained in a regression of log viability on day, conidial size, and strain. The number of time points or sample size is n.
