| Abstract:
Under Mediterranean conditions, water requirements of cherry trees are usually satisfied by the moisture stored in the soil, but irrigation improves growth and productivity. Canopy, root system and leaf water potential of five rootstocks were observed in the nursery through a growing season. Leaf water potential (ψ) differed significantly with plant spacing, the higher values being observed at larger spacing. Moderate or intense roostock pruning at planting seems to allow a higher water economy. Cab 11E was more sensitive to drought and Gisela 5 showed a better resistance, Edabriz, Maxma 14 and Prunus avium had an intermediate sensitivity to water stress. | |
