Abstract: Haloxylon ammodendron (C.A.Mey) Bunge ex Fenzl, (Saxaul forest) is a small tree and shrub belonging to the genus Amaranthaceae. We measured shoot water potential of saxaul trees, indirectly determined the current status of shoot water potential of natural forests and planted trees, the adaptability of planted trees, and assessed the adaptation of natural saxaul trees to drought. The study was conducted Bayanzag region, Umnugobi province, Mongolia. The assimilation shoot water potential was measured in natural trees differing in their age classes: adult tree (≤200 cm), young tree (80-200 cm), and juvenile (≥80 cm) according to their stem height classes. Meanwhile, planted trees were classified as 50 cm, 100 cm, and 140 cm in by stem height, and stem diameter and tree height were measured. The comparative measurements of shoot water potential revealed that young and juvenile trees are more subject to water stress than adult trees, which shows their adaptation performance in drought conditions. Similar patterns were observed in planted juvenile trees (up to 80 cm), either planted by seedlings or direct seeding. As young trees grew taller, their susceptibility to water stress decreased. Natural forest trees had lower shoot water potential values or were more susceptible to water deficit than regularly watered planted trees. In the case of the planting and watering method, hole planting and watering may be more effective than direct seeding and furrow watering, as measured by the shoot water potential measurements.
