Samuelson et al. -LRB-[2004]-RRB- showed a lag effect in the response of foliage to large changes in precipitation by correlating current growth of loblolly pine (Pinus taeda) with the previous year's LAI, and Sperry et al. -LRB-[2002]-RRB- explained how combinations of soil texture and xylem can impose «hydraulic limits» on the ability of the foliage to maintain adequate pressure potentials to support
a continuous water column.
