Figure 1:
Numbers of Meloidogyne incognita remaining inside roots, egressed from roots into the vermiculite, and total counts on four cotton isolines that differ in M. incognita-resistance genes in three experimental trials. DAI = days after inoculation. Different letters over bars within a sampling date indicate significant differences at α = 0.05. Bars with no letters showed no significant difference within a sampling date.
Figure 2:
Percentage of Meloidogyne incognita inside and outside of the roots (egressed into the vermiculite) of four cotton isolines that differ in M. incognita-resistance genes in three experimental trials. DAI = days after inoculation. Different letters over bars within a sampling date indicate significant differences at α = 0.05. Bars with no letters showed no significant difference within a sampling date.
