Haloxylon ammodendron is a commonly used sand-fixing species in the desert area of northwestern China; it has been abundantly planted in areas where annual precipitation is about 120 mm in the Hexi Corridor since the 1970s. Spatial patterns and associations of an H. ammodendron plantation in five stages of community development were analyzed in an oasis-desert ecotone to gain insights into popu...
The xerophytic desert shrub Haloxylon ammodendron (C. A. Mey.) Bunge. is distributed naturally in Asian and African deserts, and is widely used for vegetation restoration in the desert regions of Northern China. However, there are limited long-term chrono-sequence studies on the impact of changed soil properties and vegetation dynamics following establishment of this shrub on mobile sand dunes....
Haloxylon ammodendron, a perennial xero-halophyte, is an essential species for investigating the effects of drought on desert tree. To gain a comprehensive knowledge on the responses of H. ammodendron to drought stress, we specially performed the molecular and physiological analysis of H. ammodendron in response to -0.75 MPa osmotic stress for six and 24 h in lab condition via RNA-seq and digit...

BACKGROUND AND AIMS China is one of the countries most severely affected by desertification. Haloxylon ammodendron (Amaranthaceae) is an ecologically important component of the desert ecosystem and is one of the main tree species used for restoration, yet we know little about its genetic structure. METHODS Genetic variation within and between nine populations of H. ammodendron from two region...

نمونههای گیاهی جمعآوریشده متعلق به بخشAmmodendron از جنس Astragalus موجود در هرباریوم پژوهشکده علوم گیاهی دانشگاه فردوسی مشهد مورد بررسی قرار گرفتند. نتایج حاصل از این بررسی، نامگذاری و معرفی گونههای A. qohestanicus و A. khonikensis به عنوان آرایههای جدید برای دنیا است. شواهد ریختشناسی تعلق این گونهها را به این بخش نشان میدهد. این گونهها از شمال شرقی ایران، استان خراسان جمعآوری شده...
A vast area of Iran is covered by sand dunes. Biological control is an appropriate method for sand dune fixation. So, it is essential to recognize characteristics of psammophyte plant species and introducing suitable species for sand dunes. Ammodendron persicum is one of the important and compatible species in desert ecosystems. The current research was carried out to investigate the effect of ...
