36 | Water Potential | TZ | 2001-03-01 - Present | Bi-weekly during green leaf season | Oak tree leaf water potential | Leaf water potential using a pressure bomb to force water out of sprigs of oak leaves (some pine too) have been measured by many different people over the years. Generally three trees have been used (102, 255 and 92 aka Liu Kang's tree) although some times the tree ids were not recorded (2010, 2011, 2012). Also young and old pine trees but again not always recorded. Usually small sprigs of multiple oak leave were cut from the tree in multiple (sunlit, shade, different height) locations and immediately measured. Midday is the most prevalent measurement time, but many predawn measurements were done, and occasionally multiple times throughout the day. Sometimes only qualitative times of "predawn" and "midday" were recorded these were assumed to be 30min before sunrise and solar noon. |
