“…The hydraulic resistance measured in untreated control plants was similar to those reported for wheat (Hansen, 1974;Herkelrath et al, 1977) and other herbaceous crops (Steudle, 2000). The mercury-induced inhibition of water flux (53% average) was consistent with the 66% inhibition reported for wheat, with a different experimental system, by Carvajal et al (1996).…”

“…the decrease in transverse conductivity for water across the roots during drought is in agreement with other observations 7,8,14 The recovery on rewatering is often too fast to be attributable to a rapid development of new young roots. Thus real conductivity variations must be involved, such as described by Aston and Lawlor I , Brouwer 3 and Weatherley 16 .…”

SummaryIn relation to problems encountered in the urban environment a study was made of changes in the root's permeability to water of a number of tree species during a drought period, and of water conductivity during recovery. The results suggest than an important reduction of water conductivity occurs as soon as internal water stress builds up. Recovery appears to proceed irregularly. There appear to be differences in response -both as regards extent and speed -among different species.

Root system hydraulic conductivity (Lp) (6-8, 13, 14), are relatively scarce and mostly confined to small systems and terminal root segments, which cannot be expected to reflect average conditions for the whole system. We know of no attempt to determine the relationship between the average Lp and the root system size or shoot leaf area.Our purpose here is to establish the broad outline of this relationship in bean plants and to compare the magnitude of our data with field data obtained by others. MATERIALS AND METHODSPhaseolus vulgaris L. (cv. Ouray) seeds were germinated on paper towels for 4 days then transferred to 25-cm plastic pots filed with half-strength modified Hoagland solution. The date of transfer is taken as day 0. The nutrient solution was a commercial mix available from Robert B. Peters Co., 2833 Pennsylvania St., Allentown, Pa. 18104.3 The solutions were continuously aerated and the plants maintained in a controlled temperature greenhouse (27 ± 1.5 C). Supplemental sodium vapor lamps were used resulting in a mean midday flux density over the growth period of 425 ,uE m-2 s-'. Additional plants were grown without the supplemental lighting with the result that the mean light intensity was reduced over the growth period (mean midday flux density = 320
