2 , grain yield of the tested genotypes increased by a factor of 2.5 between 1915 and 2022 and the genotypic variability for yield was highly significant (F(13, 70) = 18.30, P < 0.001).

One key finding is that the VPD at which the initiation of TR restrictions occurred (VPD BP ) showed a negative trend with the ratio between the maximum canopy conductance (Slope1) and the plant hydraulic conductance (K plant , Fig. 7a ).
