In field pea(Pisum sativum) grown in temperate region of western Japan, low temperature under late seeding condition should be considered as a limiting factor for early growth. Of inhibition mechanisms, decreasing flavonoid compounds released from legume roots for nod gene activation might be of importance. Root nodule formation was investigated after inoculation in both flavonoid priming and the control. Root nodule numbers per plant were higher in flavonoid priming than the control. Plants inoculated with primed rhizobia showed alterative root structure such as reduction of the number of the second order lateral roots and the continuous nodule formation along the root axis. These results suggest that priming treatment of rhizobia with flavonoid might induce earlier formation of root nodules due to inhibiting lateral root differentiation, indicating that root system development of pea plants occurs with a trade-off between the nodulation and lateral branching under unsuitable environmental conditions.

在日本西部温带地区种植的豌豆（Pisum sativum），晚播条件下的低温应被视为早期生长的限制因素。在抑制机理中，减少豆科植物根系释放的类黄酮化合物对nod基因激活可能具有重要意义。接种后，在类黄酮引发和对照根瘤形成进行了研究。单株根瘤数在类黄酮引发中高于对照。接种根瘤菌的植株根系结构发生改变，二级侧根数量减少，根轴沿着形成连续的根瘤。这些结果表明，引发处理的根瘤菌类黄酮可能会诱导早期形成根瘤，由于抑制侧根分化，表明豌豆植株的根系发育之间的平衡发生在不适当的环境条件下的分枝和分枝。
