BACKGROUND AND AIMS Populus euphratica is a light-demanding species ecologically characterized as a pioneer. It grows in shelter belts along riversides, being part of the natural desert forest ecosystems in China and Middle Eastern countries. It is able to survive extreme temperatures, drought and salt stress, marking itself out as an important plant species to study the mechanisms responsible ...

گونۀ پده (Populus euphratica Oliv.) در مناطق وسیعی از ایران به‌طور طبیعی انتشار یافته و بومی مناطق خشک و نیمه‌خشک است. تنوع جغرافیایی و اقلیمی در گسترۀ انتشار این گونه سبب شده که اختلافاتی به لحاظ مورفولوژیکی و ژنتیکی میان درختان در رویشگاه‌های مختلف پدید آید. صفات مورفولوژیکی بذر ممکن است در تمایز ژنتیکی پده نقش مهمی داشته باشد. در این بررسی با استفاده از صفات مورفولوژیکی، بذر درختان ...

Salt stress is one of the most crucial factors impacting plant growth, development and reproduction. However, information regarding differences in tissue-specific gene expression patterns, which may improve a plant's tolerance to salt stress, is limited. Here, we investigated the gene expression patterns in tissues of Populus euphratica Oliv. seedlings using RNA sequencing (RNA-Seq) technology....

Riparian plants in arid regions face a highly variable water environment controlled by hydrological processes. To understand whether riparian plants adapt to such environments through plastic responses, we compared the root traits, biomass allocation and growth of Populus euphratica Oliv. Seedlings grown in lysimeters filled with clay or clay/river sand sediments under inundation and varying wa...

Litter decomposition plays a critical role in carbon and nutrient cycling terrestrial aquatic ecosystems. However, the effects transient flooding soil covering have on leaf litter remain unclear. The changes of mass loss stoichiometric ratio C:N (the to nitrogen), C:K potassium), C:P phosphorus), N:P nitrogen N:K potassium) fresh Populus euphratica (P. euphratica) leaves surface, flooding, trea...

Microscopic understanding of tree xylogenesis processes and their relationships with environmental factors is important for conservation. To assess the relationship between Euphrates poplar (Populus euphratica) radial growth on short time scales, micro-core samples were collected in lower Tarim River northwest China 2020. We analyzed intra-annual variation P. euphratica its environment. Our res...

This study aimed to compare the hydraulic characteristics of different vitalities of Populus euphratica to reveal the differences in their water use strategies and water consumption to provide useful data to scale water use of riparian poplar forests in the lower reaches of the Tarim River, Northwestern China. Our results showed that the sapwood area of P. euphratica could be estimated based on...
