Abstract
In this study the root hydraulic conductivity (RHC) of five peach rootstocks was tested on one-year-old potted plants.
The rootstocks were: GF 305 (peach seedling), GF 677 (almond x peach hybrid), Hansen 536 (peach x almond hybrid), GF 43 (P. domestica), GF 655/2 (P. insititia, S. Julien d’Orleans). The RHC was determined after cutting the plant four cm above the crown, applying a 0.3 MPa pressure to the roots for 14 minutes.
The liquid was collected during three periods of three minutes each.
The data show significant differences in the RHC (μg s-1 MPa -1m -1 root length) among the rootstocks, and Hansen 536, GF 305 and GF 43 had the highest values.
Roots, shoots and leaves of each rootstock were analyzed to determine their composition in total N, P and K.
