It has only been reported in a small number of trees (e.g., Sperry et al. 1994, Ewers et al. 2001). Diurnal refilling via root pressure has been reported in some crop species (Tyree et al. 1986, Stiller et al. 2003), but it is unclear whether trees employ root pressure for daily recovery of hydraulic conductivity.

举例来说， Sperry 等人 1994，大口水罐等人 2001 每日的再将注满经由根压力已经被在一些农作物种(Tyree 等人 1986，较静止的等人 2003)方面报告，但是它是不易了解的是否树雇用为水力导电率的每日恢复植根pe from prison 压力。
