callitrishydraulic {lgrdata}

Cavitation resistance for Callitris branches

Description

Measurements of so-called 'percent loss conductivity' (PLC) curves on terminal twigs of Callitris trees (a member of the Cupressaceae in Australia). Twigs are subjected to increasingly negative xylem pressure (Psi, included as a positive pressure in MPa), and the loss in conductivity (i.e. the conductivity of water transport in the xylem) is measured.

Usage

callitrishydraulic

Format

A data frame with 31 rows and 3 variables:

Rep

integer Replicate - four branches are included.

Psi

double Positive-valued negative xylem water pressure (MPa)

PLC

double Percent loss conductivity (sometimes < 0)
