摘要：

The phenolics released by red mulberry (Morus rubra L.) roots at different growth stages within a season were quantified and the makeup of phenols analyzed by reverse-phase high performance liquid chromatography (RP-HPLC). The data show that total phenols released into the soil solution increased continuously from an early vegetative stage to leaf senescence, indicating their accumulation in the rhizosphere. From the RP-HPLC analysis of the butanol-extractable phenolics at various growth stages, there appears to be a massive release of an assortment of less polar phenolics into the rhizosphere at the end of the season accompanying leaf senescence. The rhizosphere phenolics may create an environment suitable for the biodegradation of recalcitrant environmental pollutants, by selectively fostering the growth of some, while inhibiting the growth of other microbes.
