In order to evaluate the relative sensitivity to water stress of several physiological responses in English walnut (Juglans regia var. Chandler on Paradox seedling rootstock), several greenhouse experiments were conducted. One experiment was conducted in September 2015 and the remaining experiments were conducted in April through September 2016. Air temperature, relative humidity, and vapor pressure deficit (VPD) were monitored continuously in the greenhouse for both experiments. Physiological responses monitored included stem water potential (SWP) stomatal conductance (Gs), transpiration (T), maximum daily stem shrinkage (MDS), leaf growth (LG), and stem growth (SG). SWP, MDS, and Gs tracked similarly with each other contrary to literature suggesting MDS as more sensitive than SWP. In order of most responsive to reductions in SWP to least responsive the physiological responses separated out as follows: SG>MDS=GS>T>LG. Surprisingly, contrary to classic water relations literature, LG was found to be least responsive to water stress. Further examination of the diurnal patterns of LG revealed that at more severe levels of water stress, leaves on the water stressed plants had a larger percentage of their total daily growth happen during the early morning than did the control leaves. Response of MDS to SWP for each individual tree suggested that use of MDS in a field setting would require individual calibration for each tree in order to estimate absolute values of water stress when using dendrometry.
