We compared soil-to-leaf hydraulic conductance (G (T)), hydraulic conductivity and water-relations characteristics of leaves between reiterated axes (produced by sprouting of suppressed buds) and sequential axes (produced by elongation of terminal buds) on the same branch to investigate how basal reiteration affected the hydraulic architecture of mature Cinnamomum camphora (L.) Sieb. trees. Given similar light conditions, G (T) was higher for leaves on reiterated shoots than for those on sequential shoots. However, where leaves on sequential shoots received more light, G (T) was similar to that of leaves on reiterated shoots, suggesting that some compensatory mechanism worked to increase hydraulic conductance to the more distal sequential shoots, which have higher potential for carbon gain. Both xylem- and leaf-specific conductivities were higher for reiterated than sequential shoots. Pressure-volume measurements indicated that leaves on reiterated shoots were more vulnerable to water stress, suggesting that they developed under favorable water status. Because basal reiteration occurs on lower-order branch axes, reiterated shoots have better connectivity to higher conducting xylem and this may contribute to favorable water status. As trees grow larger, hydraulic pathlength and hydraulic resistance both increase as numbers of branch junctions and nodes increase. Our results suggest that basal reiteration improves the hydraulic functional status of mature C. camphora trees by shortening the hydraulic pathway and increasing hydraulic conductance to transpiring leaves.
