[The effect of the phenolic compounds exuded by pea roots in darkness on the reproduction of Rhizobium].
The exudation, composition, and biological activity of the phenolic compounds (PC) of pea (Pisum sativum L.) roots in the light and darkness were studied. The roots of leguminous plants grown for 5 days in darkness exuded a smaller amount of PC that displayed a weaker stimulation of Rhizobium reproduction. Moreover, the root exudates contained antimicrobial compounds, stilbenes. It is assumed that a lower PC exudation by roots and the specific features of PC composition influencing the biological activity are among the reasons causing a delayed nodulation of legumes grown in darkness.
