Figures & Tables

Gall and egg formation of Meloidogyne javanica (A and B), M. incognita race 3 (C and D), and M. arenaria race 1 (E and F) on cultivars of oilseed radish, white (Tachiibuki) and black (Pratex) oats under greenhouse conditions. Tomato cv. Rutgers was used as a susceptible host. Gall severity was assessed based on a scale 0 to 5 where 0 = no galls, and 5 ≥ 100 galls on roots. Data are the mean of two trials with ten replicates. Bars with the same letter(s) are not significantly different based on the Tukey’s test.

Representative images of roots of oilseed radish cv. Eco-Till (A) and oat cv. Pratex (B) infected with Meloidogyne arenaria at 28 days after inoculation.

Hematoxylin-Eosin stained cross sections of root tissues of oilseed radish cv. Carwoodi (A) and Eco-Till (B) infected with Meloidogyne incognita at 28 days after inoculation. N, female nematode; GC, giant cell.

Cross sections of root tissues of oat cv. Pratex (A) and Tachiibuki (B) infected with Meloidogyne javanica at 28 days after inoculation. N, female nematode; GC, giant cell.

Number of second-stage juveniles (J2), and young and adult (egg-laying) females of Meloidogyne spp_ in roots of oilseed radish (Eco-Till, susceptible; Carwoodi, resistance) at early-stage of infection (1, 3, and 5 days after inoculation; DAI) and at 28 DAI in the greenhouse_
