Editing Cavitation (section)

===Vascular plants===
Cavitation can occur in the [[xylem]] of [[vascular plants]].<ref>{{cite journal |last1=Caupin |first1=Frédéric |last2=Herbert |first2=Eric |title=Cavitation in water: a review |journal=Comptes Rendus Physique |date=2006 |volume=7 |issue=9–10 |pages=1000–1017 |doi=10.1016/j.crhy.2006.10.015|bibcode=2006CRPhy...7.1000C }}</ref><ref name="Sperry96" /> The [[sap]] vaporizes locally so that either the vessel elements or [[tracheid]]s are filled with water vapor. Plants are able to repair cavitated xylem in a number of ways. For plants less than 50&nbsp;cm tall, root pressure can be sufficient to redissolve the vapor. Larger plants direct solutes into the xylem via ''ray cells'', or in [[tracheid]]s, via osmosis through [[plant cell|bordered pits]]. Solutes attract water, the pressure rises and vapor can redissolve. In some trees, the sound of the cavitation is audible, particularly in summer, when the rate of [[evapotranspiration]] is highest. Some deciduous trees have to shed leaves in the autumn partly because cavitation increases as temperatures decrease.<ref name="Sperry96">{{cite journal |author1=Sperry, J.S. |author2=Saliendra, N.Z. |author3=Pockman, W.T. |author4=Cochard, H. |author5=Cuizat, P. |author6=Davis, S.D. |author7=Ewers, F.W. |author8=Tyree, M.T. |date=1996 |title=New evidence for large negative xylem pressures and their measurement by the pressure chamber technique |journal=Plant Cell Environ. |volume=19 |pages=427–436|doi=10.1111/j.1365-3040.1996.tb00334.x }}</ref>
