Fig. 4. Nematode infection assays in –7, –3, and 0 P. indica-treated and control plants. (A) Number of nematode infection sites per cm
of root length at 3 dpi. (B) Number of developed nematodes per cm root length at 15 dpi. (C) Number of second-stage juveniles hatched
from single cysts at 60–75 dpi. (D) Average length of syncytia associated with female nematodes at 10 dpi. Values are mean ± SE
(n = 3); different letters indicates significant difference (Tukey test, P < 0.05).
