“…In fact, sheathed com roots have higher water contents than older, bare regions (Wang et al, 1991), and rhizosheaths of Oyzopsis hymenoides have more water than the surrounding soil (Bristow et al, 1985). Increasing experimental evidence with both xerophytic and mesophytic plants indicates that water can move from their roots into the surrounding soil, pulled out, passively, by the lower water potential of the soil (Shone and Flood, 1980;van Bavel and Baker, 1985;Caldwell and Richards, 1989;Blum and Johnson, 1992;Dawson, 1993) or pumped out, actively, by the root (Schwenke and Wagner, 1992). However, the experimental design used here did not allow us to distinguish between these two mechanisms.…”

“…The tendency of root L, to change in response to water availability, i.e., for roots to behave as rectifiers, has been investigated with respect to the structural characteristics of hypodermal sleeves in Zea mays (Shone and Clarkson, 1988). Other anatomical studies, though not specifically addressing root rectification, have similarly focused on the role of the hypodermis (exodermis) in regulating radial water flow (Oleson, 1978;Clarkson et al, 1987).…”

“…Agave deserti, a perennial leaf succulent of the Sonoran Desert, was used because its roots have been shown to act as rectifiers (Nobel and Sanderson, 1984). After plants were subjected to drying and in some cases rewetting in soil, whole roots and root segments were used for concurrent determinations of changes in tissue anatomy and Lp ; Lp was measured by the technique ofvacuuminduced flow (Shone and Clarkson, 1988). Based on morphological criteria (palta and , roots were classified as old or young nodal roots, previously designated "established roots," arising from nodes at the base ofthe stem; or as lateral roots, previously designated "rain roots," arising as branches from nodal roots.…”
