Figure 4

The evolution of predawn leaf water potentials ( Ψ pd ) in the leaves of C. canephora. The clones 14, 22, 73 and 12 of C. canephora var. Conilon were grown in a greenhouse under water stress. The rate of decrease of Ψpd (RDPWP) is indicated for each clone without irrigation (NI) in MPa day-1 m-2 (A). Different small letters represent significant differences between means for drought-stressed clones by the Newman-Keuls test at P ≤ 0.05 (clone effect). Values are means ± SD of three replicates. (B) For each clone, Ψpd evolutions are presented relative to the days after water withdrawal (Δ, clone 22-NI; ▲, 14-NI; ■, 120-NI and , 73-NI).
