1 | Sperry, John S. | Hydraulic consequences of vessel evolution in angiosperms | We tested two hypotheses for how vessel evolution in angiosperms influenced xylem function. First, the transition to vessels decreased resistance to flow--often considered the driving force for their evolution. Second, the transition to vessels compromised safety from cavitation--a constraint emergi... | Cavitation; Resistivity; Perforation | 2007 |
