Conversely, significant differences occurred with nematodes Originally sampled in Morelos: at 1.5 h after assay initiation, more virulent J2s raised root tips compared to avirulent ones ( P = 0.038); this trend was reinforced and became highly significant ( P < 0.0001) at 3, 4.5, and 6 h (Fig. 3 B).
