英文摘要	Lasiurus scindicus Henrard is a drought tolerant grass frequently grown in arid to semiarid areas of Pakistan. However, information about the anatomical adaptations in L. scindicus under drought stress is not well known. Therefore, four naturally adapted populations of L. scindicus collected from Thal (TH) Salt Range (Kalar Kahar; KK), Chiniot (CN) and Cholistan (CH), Punjab, Pakistan were grown in pots at 40, 60, 80 and 100% water holding capacity (WHC) to examine their anatomical adaptations under drought stress. Moreover, half of soil saturation percentage was considered as 100% WHC and taken as control. Plant anatomical parameters like leaf thickness, epidermal thickness, sclerenchyma thickness, cortical cell area, metaxylem area and bulliform cell area were studied. In all populations from different ecological habitats, major anatomical modifications regarding leaves were reduced leaf lamina, well developed bulliform cells, and increased cuticle thickness under severe drought stress accompanied by thick epidermal layer for moisture conservation. Some specific root anatomical adaptations like increased lignification in pith and cortical cells, increased endodermal thickness, and size of xylem vessels were also observed under drought stress. Likewise, reduced stem, metaxylem and phloem area was also noted under drought stress, which played important role for increasing the plants capability to cope with drought stress. Due to these adaptations, L. scindicus plants markedly lowered transpiration rate and improved the additional storage capacity under drought conditions. Based on these anatomical adaptations observed in all populations under drought, these populations may be rated in order of drought tolerance as CH>TH>KK>CN. In conclusion, well-developed thick cutinized leaves, reduced metaxylem and phloem areas, and well developed bulliform cells are the major anatomical adaptations observed in L. scindicus to induce drought tolerance.
