英文摘要	Key message Overexploitation of Salvadoraoleoides for medicine and animal fodder along with significant habitat loss in its natural ranges is causing a continuous decline in natural populations. Although, the IUCN Red List categorizes it as data deficit, there are some reports indicating that its natural populations are vulnerable in many regions of the world indicating the need of quick action to prevent further decline. The current study is an effort to link morphological, physiological and anatomical features with heterogenic environments of its natural distributional ranges in dry regions and how these structural modifications can be exploited for its sustainable conservation and re-vegetation to maintain forest cover of desertified systems. Salvadoraoleoides Decne. is a xerophytic perennial plant species of Salvadoraceae family, widely distributed in arid and semi-arid regions of Punjab, Pakistan. Fifteen populations of this species were collected from five diverse habitats of Punjab province, i.e., roadside, river or canal banks, deserts or semi-deserts, saline land, and mountainous range to investigate their key features associated with ecological success of this species across environmental heterogeneity. Growth and biomass production, parenchyma cell size, oil glands, stomatal density on adaxial side of leaves, ionic contents, organic osmolytes (proline and glycine betaine), and antioxidants (SOD, CAT and POD) were the maximum in populations from saline areas (LAS and RUM). Desert populations exhibited specific modifications in growth attributes such as increased shoot length, leaf area and number of leaves per branch, widened metaxylem vessels, increased proportion of phloem and storage parenchyma, and high abaxial stomatal density were observed. Xeromorphy was high in populations colonizing along roadsides as evidenced by an intensive sclerification, increased epidermal thickness, formation of distinct collenchyma layer, and dense hairiness on the surface of stems. The canal or river bank populations possessed very large stem radii, vascular bundles, metaxylem vessels and storage parenchyma cells in stems. The population from the mountainous range exhibited thick leaves, greater mesophyll proportion, large vascular bundles and stomatal density on adaxial side. In conclusion, all these features reflect the tolerance capacity of S.oleoides against environmental adversities such as salinity, drought, and temperature fluctuation of the arid region. The plasticity of physio-anatomical attributes of this species with respect to adaptability to different environments can be helpful in performance of this species in arid regions under climate change in its native region as well as in desolated areas for carbon sequestration and maintenance of ecosystem services.
