| Abstract: | The contents of nutriment and some secondary metabolites in fibrous roots of soybean seedlings were determined at 17 days after inoculation with race 4 of Heterodera glycines. The results showed as follows; The content of total sugar in infected roots of susceptible control, Ludou 1, was 46. 01% higher than that in healthy one, meanwhile the contents of total sugar were 24. 91% and 37. 77% lower in the roots of two resistant varieties, Huipizhihei-dou and Yuanboheidou, respectively. Compared to their corresponding healthy roots, the contents of fructose, maltotetrose increased 144. 30% and 62. 90% in infected roots of cultivar Ludou 1 respectively, whereas they decreased or increased to a smaller extent in the roots of resistant cultivars. After inoculation, the increasing percentages of the concentrations of total free amino acid as well as arginine, glutamic acid, alanine, aspartic acid, leucine, valine in roots of cultivar Ludou 1 were higher than that in the roots of two resistant cultivars. The contents of cystine either in infected roots or in healthy roots of the two resistant cultivars were all zeros. In response to inoculation, the increases of the contents of total phenolics, chlorogenic acid and fer-ulic acid in the roots of resistant cultivars, Huipizhiheidou and Yuanboheidou, were one time to several times more than these in the roots of susceptible control, Ludou 1. At the same time, the contents of flanvonoid and lignin varied diversely between resistant cultivars and susceptible one, which increased in infected roots of resistant cultivars and decreased in infected roots of Ludou 1 after inoculation. |
