Effect of SnebYK on inducing systemic resistance to Heterodera glycines using a split root system in soybean. (A) Effect of SnebYK on the penetration and development of H. glycines in the responder root system. (B) Effect of SnebYK on the proportion of each developmental stage of H. glycines in the responder root system. Numbers of H. glycines in responder roots were counted 15 days after inoculation. J2, J3, and J4 indicate second-, third-, and fourth- stage juveniles of H. glycines, respectively. Error bars represent standard deviations, and different letters (a, b) above the bars indicate significant differences at P < 0.05 according to a t-test (n = 4).
