Selection of Drought-Resistant and Salt-Tolerant Plant Species in the Taklamakan Desert

Abstract

Abstract: The drought-resistances of 16 representative sand-fixing plant species in the Taklamakan Desert area are analysed by comprehensive evaluation method,and the salt-tolerances of 6 plant species are observed through pot experiment irrigated with different salt concentration water.The 16 drought-resistant plant species can be ranked by their resistance to drought as:Tamarix hohenackeri>Haloxylon ammodendron>T. austromon-golica>H. persicum, Caragana korshinskii, Artemisia arenaria, Calligonum leucoladum,C. rubicundum>C.angustifolia>Halimodendron holodendron>Atraphaxis pungens, C. roborovskyi>Populus euphratica>Elaeagnus angustifolia>Populus simonii; while the 6 salt-tolerant species can be ranked as:Tamarix hispida>T. ramosissima>Nitraria sibirica>Haloxylan ammodendron>Halimodendron haloden-dron>Ammodendron argenteum. The habitat adaptability of different sand-fixing plants are also discussed.

Key words: wheat, FACE, flag leaf, photosynthetic pigment, grain mass.
