The annual growth was calculated as the sum of internodal lengths produced during each annual cycle. The letters correspond to Tukey posthoc HSD multiple comparison testing for significant differences between years for each location, the same letters means no significant differences within one location (P > 0.05).
*The measurements in Thuwal-Kaust were conducted one year earlier than those at other locations.
