为了验证植物胁迫相关诱导子顺式茉莉酮（cJ）在大豆豆荚中提供对吸种蝽害虫英雄美洲蝽（Euschistus heros）的保护的假设，使用3个昆虫敏感性不同的大豆品种，即BRS 134（敏感）、IAC 100（抗性）和Dowling（抗性），研究了英雄美洲蝽在cJ处理的豆荚上的生长。当饲喂CJ处理的Dowling时，英雄美洲蝽表现出体重增加减少，而当饲喂其他处理的品种时，没有观察到对体重增加的影响。使用方差分析，观察到黄酮苷大豆苷和染料木苷及其相应的苷元、大豆苷元和染料木黄酮浓度之间存在三因素（品种x处理x时间）相互作用。在CJ处理的Dowling中，染料木黄酮和染料木苷浓度分别在处理后144和120 h增加。与BRS 134和IAC 100相比，在Dowling中观察到更高浓度的丙二酰大豆苷和丙二酰染料木苷，与时间无关，在CJ处理的种子中观察到最高浓度。与Dowling相比，BRS 134和IAC 100中的大豆球蛋白和丙二酰大豆球蛋白水平更高。典型变量分析表明，大豆黄酮（在前两个典型变量）和染料木素（仅在第一个）是重要的判别变量。这些结果表明，CJ处理导致未成熟大豆种子中潜在防御性雌虫水平的增加，但对英雄雌虫表现的负面影响取决于品种。大豆豆荚的顺式茉莉酮处理改变类黄酮水平，并以品种依赖性方式对英雄美洲蝽生长产生负面影响。顺式茉莉酮（cJ）影响大豆未成熟种子中防御类黄酮的水平。吸种蝽害虫，英雄美洲蝽的体重增加，减少cJ处理的CV喂养时。只有道林。CJ处理对英雄绒螯蟹生产性能的负面影响是品种依赖性的。
To test the hypothesis that the plant stress related elicitor cis-jasmone (cJ) provides protection in soybean pods against the seed-sucking stink bug pest, Euschistus heros, the growth of E. heros on cJ-treated pods was investigated using three soybean cultivars differing in insect susceptibility, i.e. BRS 134 (susceptible), IAC 100 (resistant) and Dowling (resistant). E. heros showed reduced weight gain when fed cJ-treated Dowling, whereas no effect on weight gain was observed when fed other treated cultivars. Using analysis of variance, a three factor (cultivar x treatment x time) interaction was observed with concentrations of the flavonoid glycosides daidzin and genistin, and their corresponding aglycones, daidzein and genistein. There were increases in genistein and genistin concentrations in cJ-treated Dowling at 144 and 120 h post treatment, respectively. Higher concentrations of malonyldaidzin and malonylgenistin in Dowling, compared to BRS 134 and IAC 100, were observed independently of time, the highest concentrations being observed in cJ-treated seeds. Levels of glycitin and malonylglycitin were higher in BRS 134 and IAC 100 compared to Dowling. Canonical variate analysis indicated daidzein (in the first two canonical variates) and genistein (in the first only) as important discriminatory variables. These results suggest that cJ treatment leads to an increase in the levels of potentially defensive isoflavonoids in immature soybean seeds, but the negative effect upon E. heros performance is cultivar-dependent. cis-Jasmone treatment of soybean pods changes flavonoid levels and negatively affects Euschistus heros growth in a cultivar dependent manner. cis-Jasmone (cJ) affects levels of defence flavonoids in immature seeds of soybean, Glycine max. The weight gain of the seed sucking stink bug pest, Euschistus heros, is reduced when fed on cJ-treated cv. Dowling only. The negative effect of cJ treatment upon E. heros performance is cultivar dependent.
