Abstract

Drought-induced tree mortality has been recently increasing and is expected to increase further under warming climate. Conversely, tree species that survive under arid conditions might provide vital information on successful drought resistance strategies. Although Acacia (Vachellia) species dominate many of the globe’s deserts, little is known about their growth dynamics and water-use in situ. Stem diameter dynamics, leaf phenology, and sap flow were monitored during 3 consecutive years in five Acacia raddiana trees and five Acacia tortilis trees in the Arid Arava Valley, southern Israel (annual precipitation 20–70 mm, restricted to October–May). We hypothesized that stem growth and other tree activities are synchronized with, and limited to single rainfall or flashflood events. Unexpectedly, cambial growth of both Acacia species was arrested during the wet season, and occurred during most of the dry season, coinciding with maximum daily temperatures as high as 45 °C and vapor pressure deficit of up to 9 kPa. Summer growth was correlated with peak sap flow in June, with almost year-round activity and foliage cover. To the best of our knowledge, these are the harshest drought conditions ever documented permitting cambial growth. These findings point to the possibility that summer cambial growth in Acacia under hyper-arid conditions relies on concurrent leaf gas exchange, which is in turn permitted by access to deep soil water. Soil water can support low-density tree populations despite heat and drought, as long as recharge is kept above a minimum threshold.

Notes

  1. The genus (Acacia) was recently split (Kyalangalilwa et al. 2013) into two different genera, Vachellia and Acacia. While the original name (Acacia = "thorn" in latin) was reserved for the Australian (thornless) Acacia trees, the new name, Vachellia, was reserved for the Acacias from the rest of the world, with thorns. Searching the web science for scientifc papers published from 2015 to June 2016 showed that only 2.6% from the 346 Acacia papers published during this periord chose to use the new name. A short survey among Israel’s botanists also demsonstrates that it is preferable to continue to use the genera name Acacia (see for example Winters et al. 2015; Nothers et al. 2017; Rodger et al. 2018). For these reasons, we chose to use the genera Acacia.

Four trees of Acacia raddiana (red) and two trees of A. tortilis (black) showed relatively large diurnal amplitude during the growing season and only small amplitude outside the season, matching growth with xylem and phloem activity. Stem shrinkage and relaxation during the light and dark hours, respectively, suggest the development of a water potential gradient during the day
