| Abstract/Contents: | "Seedling 'Tennessse Natural' peach [Prunus persica (L.) Batsch] trees were grown in a series of five greenhouse experiments to determine how peach root development was affected by the interaction of soil pressure potential and the presence of Kentucky-31 (K-31) tall fescue (Festuca arundinaceae Schreb.). Peach trees were grown in split-root rhizotrons that had four separate root growth sections. When two of the four sections had live sod (LS) and two remained bare soil (BS), there was no effect of the LS on peach root development when the trees were irrigated daily. Peach root development was reduced in BS and LS treatments when soil pressure potential was less than -0.06 MPa. In contrast, when trees were grown in rhizotrons that had all four sections with either LS or a killed K-31 sod (KS), peach root development was reduced in the LS treatment compared to the KS treatments when irrigated daily or when soil pressure potential reached -0.03 MPa. The apparent root surface water potential of peach trees in the LS treatment was -0.4 MPa lower than that in the KS treatment under daily irrigation due to the interference of the K-31 tall fescue. In two additional experiments using peach trees with BS in all four sections, we maintained three sections at field capacity and allowed one section to dry to -0.06 to 1.5 MPa. During the night, when transpiration was low, water was transferred to the dry soil section via the peach root system from the three wet soil sections. It appears that the root system of peach can maintain root development in the presence of tall fescue by transferring water from regions of high water availability to those of low availability. |
