.After TIO, AGB and plant cover values were consistently higher in the control compared to water restriction treatment (Fig. 4). Water restricted AGB at final harvest was 70.3%, 66.0% and 54.3% of control values for Sarnav, Unica and Désirée, respectively. At water restricted senescence onset, plant cover was 63%, 62.1% and 47% of the control values in Sarnav, Désirée and Unica, respectively. TB after TIO was also consistently higher under control in the three genotypes (Fig. 4G–I). Final TB under water restriction was 44.6%, 40.7% and 36.8% of the yield obtained at the control for Sarnav, Désirée and Unica, respectively.
