Résumé :
|
Orchard trials on the effect of salinity on fruit tree rootstock combinations typically call for leaving border trees between treatments, thus limiting the number of combinations that can be evaluated and making these experiments expensive and rare. Five salinity dilution ratios were applied to orchard trees through regular drip lines by different combinations of regulated in-line drippers. This enabled the construction of an orchard experiment without border trees, with the salinity increasing linearly along the orchard rows. Leaf analysis after application of salinity for approximately 150 days revealed significant correlations between the applied dilution ratio and the concentrations of Cl, Na and K in the scion leaves of some of the rootstock combinations.
